laptop making a whirring noise after downloading Ubuntu ISO file

[Adam]

Laptop making whirring noise after downloading Ubuntu ISO file.

Thought the HDD might be the problem. Took out the HDD and cloned it. Quiet. No problem.

Blew compressed air to clean the fan. Not much dust.

Put everything back together. The whirring noise is still there.

What else can it be ?

Thanks, but there's no info about removing/replacing optical drive in User’s Manual...

Found some YouTube videos...

Look for the manuals for your machine not videos of what someone
is doing with a similar machine.

YouTube videos are good for simple problems.
CD drives are easy to remove generally. Usually held
by a single screw and friction.

Again, no info in User's Manual about removing/replacing optical drive.
YouTube video was the next best thing (despite being off by a revision or two) I could find.

Got the optical drive out through the HDD bay after removing two screws from
the outside holding the optical drive in place. Saw an optical drive screw hole from
the HDD bay. Got leverage of the screw hole with a phillips screwdriver and pushed the optical drive out.

Here's a pic of the "old" optical drive...

Using basic Linux features is not too bad, advanced Linux configuration can get quite gnarly. :-)

I'm still at Level 2-ish. Highest Level 5 is for gurus (like Paul, et al). :-)

You over-interpreted CaseYin's message.

The answer you got was to:

1) Press the eject button located on the optical drive tray.
2) The optical drive tray opens a fraction of an inch.
Laptop optical drives do not have full motor assist
and long-travel trays. Just the spring releases and
the tray must be manually moved open with your fingers.
3) Now, grab the exposed portion of the tray and open the
tray just a little bit, to check for a mini-CD or a
regular-sized piece of media.

Media placed in a laptop drive, usually has an interference-fit.
The media presses the hub and compresses it a bit.
To remove the media, requires the hub to "let go" of
the center hole. You have to ease the CD or DVD or mini-CD
off the hub.

Once the media is removed, close the tray again.

The tray motor does not rotate if no media is present.

If the tray motor does not rotate, there will be silence.

If the optical beam detects an obstruction in the way
that is interpreted as media, then the motor spins the
media so that the laser can go and find the groove.

The motors that rotate such things, tend to be three-phase.
Rather than media being rotated by stepper motors. Three
phase motors have low torque ripple, giving "smooth data bits".

Three phase motors, there's a motor controller chip, and
it makes three sine waves that are out of phase. The motor
controller can vary the frequency of the since waves, it
can vary the amplitude. This allows a motor controller to
accelerate or decelerate the media. Since optical media
does things like CAV (constant angular velocity) or CLV (constant
linear velocity), the equipment is full of tricks. By
varying the frequency, the media can spin screaming-fast
at 48X ("whoosh" noise), or movie-slow at 1X (barely audible).
This is why the noises that come out of there, can vary a lot.

But without media in there, it would be a defect for the
motor to start spinning. It would require a detection
defect, for the motor to rotate when no media is present.
The motor may "blip" a bit, at the instant the tray
closes, but it should not stay running.

CaseYin did not want you to do "surgery". That's not the request.

Simply open the tray and check for media! That was the answer.

Thanks, Guru Paul !!

Because the tray was already empty, I got his hint that
the problem may be optical drive-related. So, going one step further,
I removed the optical drive entirely.

Anyways, got the optical drive out through the HDD bay after removing two screws from
the outside holding the optical drive in place. Saw an optical drive screw hole from the HDD bay.
Got leverage of the screw hole with a phillips screwdriver and slid the optical drive out.

Here's a pic of the "old" optical drive...

https://i.postimg.cc/L8JNK1Cb/IMG-0079.jpg

It's old so I'll replace it. How about an external USB Lite-On Optical Drives EBAU108-01 ?
Internal optical drives are harder to match. Maybe I'll disable the optical drive via BIOS and
stick the old optical drive back in to fill the hole.

After removing the optical drive, the laptop is still quite noisy.
What else can be the cause ?

I'm getting nervous and have been planning to move to a newer laptop.
Specs are different so simply inserting the HDD in the newer laptop didn't work.
Had graphics issues because video is different [ATI Mobility Radeon (old) vs Intel HD Graphics (newer)].
Is there a workaround ? Or, do I need a new install of Ubuntu ?

I don't see a price, but depending on whether this seller ships to
where you are, you might see a price.

There's no real reason to pull the drive if it's not the
noise source.

Maybe the machine has two cooling fans.

*******

If using non-proprietary video drivers (nouveau or similar),
the OS should probe at boot time and select the driver that
matches the current crop of hardware.

That's how my Linux Mint USB stick (the one I use all the time
for forensics), is able to boot on the various machines. It won't
boot on the first computer, because it doesn't have the memory for it.

When the OS is installed, it's still transportable. In fact, that's
how I got Linux running on one of the machines (which doesn't know
how to boot a DVD and the USB is only USB 1.1). I installed on a
more capable machine (32 bit version), then moved the hard drive
over to the machine in question and it booted.

So there is transportability.

*******

If you had a stethoscope, you could press that on the
surface and search for "peak sound" :-) Sound questions
are pretty tough to solve from a distance, even with
a sound sample.

They make array microphones, but I don't know if there
is the right kind of software to use with them. There
is a very expensive array microphone, that has "beam steering",
and allows extracting "tracks" from a live recording.
You can record a band, use the software, and extract
a "drum track", a "lead singer track" and so on, and
it's all done by beam forming of the signals,
as a step in post. Then if another sound engineer
wants to mix down the tracks, they can take the
artificially produced tracks and use them.

Without the beam steering, the recording would already be mixed
in the broad sense (each individual microphone, only
hears what one ear on your head would hear. But using
maths and phase relationship, it's possible to "point"
the microphone array in a virtual sense and extract
just a portion of the soundscape. The more microphones
used, the tighter the virtual beam can be. Like, with
two microphones (the way the human head works), it's
still possible with neural processing, to pick out
a particular conversation in a crowd. The software
phased array approach, is just less clever.

Some little academic projects, the grad students
use 64 microphones. As proof how bored they are.
When you do that, attention to detail counts, and
the recording chips need to be sampling using
a common clock and synchronization. Just buying 64
USB microphones off Amazon might not work so well.

By using technology like this, it's possible to
scan an item (in post-processing) and determine the
locus of the sound source. A stethoscope is cheaper.

Yes, you both (Azigni) might be right about the fan shifting into high gear.
When I put my ear (stethoscope :-) closer to the keyboard,
the sound was more toward the center-left of the keyboard away from
the drives, HDD & optical, on the right half of the keyboard).
Maybe the CPU thermal compound/paste got toasted after
downloading the Ubuntu ISO file ? Yikes !!

Here's a pic of the motherboard...

https://i.postimg.cc/cCdBxkmh/IMG-0091.jpg

Center-left of the keyboard would be right over the CPU.
Now that's what I call surgery. :-)

Why did Dr. Fauci have to go and make Fry's close ?

Then, the problem may be the newer laptop has hardware that
is not supported by the existing Ubuntu version in use. So,
I will install a newer version of Ubuntu then.

Not supported? I get an approx date of 2013 for your laptop. I have a
Thinkpad L530 of basically the same era running 20.04 LTS no problem...

Thanks, is it normal for the cooling fan to kick into
high gear after starting the laptop for only minutes (~15) ?
I've been shutting down the laptop for fear that
it'll completely fail before I get all data from it.

I've been powering it on only when absolutely necessary.

Well, my Dell Desktop does the same sometimes, I don't know if it's
normal or not though.

I was able to run "top" but copying the output was tricky because of the way top updates.
Anyways, I was able to quickly "Select All" then copy several times the output to a text file (top.txt).
But, I was not able to copy the top.txt file to my USB thumb drive.
Something seems to be wrong with file transfer.

I had copied a folder called "Taxes-Current" the other day after the noise appeared.

But, contents looks like garbage...

Maybe the controller in the Rally2 or the Flash Chip in the Rally2.
I have a Rally 2 here as well, and mine is 8GB. Both the dates and
file sizes are corrupt in your picture.

I would guess, just a bad USB stick.

Move the stick to a second, known good machine, and see if it
still displays as bad.

Read and write test the Rally 2, on the known-good computer.

Then stick the Rally2 back in the defective machine and see
if bytes are still getting corrupted.

If the 5V rail was lower in voltage than normal, that
might cause flash corruption on reads. Since the Rally2 has
that nice orange LED, compare the brilliance of the orange LED
on the known-good computer, versus on the HM55 based machine.

If the HM55 based machine has three USB ports, they might not
all be defective. A single power monitoring chip, runs two
USB ports. A laptop typically has three ports, so one of the
ports may work better than the other two.

You may be on to something.

Pics were all taken from a known good laptop. I haven't been able to
get anything out of the noisy bad laptop.

I just tried to copy another folder (from the known-good laptop) to the Rally2 USB stick...

https://i.postimg.cc/qqZn527k/Error-while-copying-folder.png

The USB stick has become read-only. I can still read old files that
were written before the USB stick lost write capability.

GParted shows a key next to the partition...

Strange !! How'd that happen ? Is that why the Rally2 USB stick is now read-only ?

Some USB sticks become read-only when failing to protect existing data.
Sandisk is on brand that has such feature. My guess is your Rally2 USB
stick "pining for the fjords" like an infamous parrot.

Guess it's about time since it was purchased before the following May 2012 purchase...

https://i.postimg.cc/hPFfhnGG/OCZ-Mod-XStream-Pro-600-W-Modular-High-Performance-Power-Supply.png

First OCZ product I purchased was...

OCZ Rally2 16GB USB 2.0 Flash Drive Model OCZUSBR2DC-16GB
https://www.newegg.com/model-oczusbr2dc-16gb/p/N82E16820227272

but I can't locate purchase order for date info.


Hmmm...wonder if I could burn "Taxes - Current" folder to a data disc.
Don't want to risk losing another USB stick just in case.

Cloned the bad USB stick. How to unlock ? Searched but no luck.

It is it the safety feature of the USB stick as I described then you
cannot. Its trigger by the flashes controller. Get a new thumbdrive can
copy what you can before it becomes total dead.

Yes, I cloned it but the clone keeps the lock. So, ALL files are read-only even after cloning ?
And, there's no way out ? Not good.

What does /etc/mtab say for the mount ?
Is it "... -o ro" for read-only ?
Maybe it needs "sudo remount -o rw" type treatment.

I thought a topic like this came up recently,
something that was mounting read-only.

Just the two (2) partitions for the USB stick clone...

/dev/sda1 /media/ubuntu/RALLY2 vfat ro,nosuid,nodev,relatime,uid=999,gid=999,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro 0 0
/dev/sda2 /media/ubuntu/SPBLAZE64GB vfat rw,nosuid,nodev,relatime,uid=999,gid=999,fmask=0022,dmask=0022,codepage=437,iocharset=iso8859-1,shortname=mixed,showexec,utf8,flush,errors=remount-ro 0 0

Looks like the clone inherited the lock for the entire USB stick. I created /dev/sda2 partition thinking that I'll copy the files over but that inherits the lock too.

The documentation isn't very good in any case.

Linux:
blockdev, hdpart

Windows
diskpart

*******

https://docs.microsoft.com/en-us/windows-server/administration/windows-commands/attributes-volume


diskpart

select volume X
attributes volume clear readonly
attributes volume set readonly

But part of what the Windows one is doing, is reflected
in a registry entry, which means when the storage device
is unplugged and moved, the attribute doesn't travel with it.
That suggests diskpart won't be the repair tool to use.

Linux has a couple. The stick is likely to need removal
and reinsertion, for any successful change to be re-parsed
and used by the OS.

https://serverfault.com/questions/678008/ubuntu-remount-a-root-mount-thats-changed-to-ro-as-rw-without-rebooting

hdparm -r0 /dev/sd???
blockdev -setrw /dev/sd???

These imply some sort of hardware level change. I can
find comments that an attribute may apply to the whole
device, so if you applied to /dev/sda1, it would apply
to the whole device /dev/sda. Suggesting it is stored
somewhere in the MBR.

But the level of documentation always seems to be the
same on utilities at this level

1) Terse manpage - in other words "if you don't know what
you're doing, we're not going to help you".
2) No traceability - never a description of what hardware
bits or bytes are being modified. Almost as if the
developers don't know what they're doing.
3) Polite request in bugtracker to fix fucking documentation,
add note to manual page that OPs apply to MBR and not
to partition, cheerfully ignored.

This is almost as bad as the "dirty bit" on Windows file
systems indicating they need to be checked. For the longest
while (years!) you could have a volume that kept getting
CHKDSK automatically at startup. An autochk (that always
runs), sniffs the "dirty bit" and starts a CHKDSK, then
CHKDSK doesn't clear the "dirty bit" and the charade starts
all over again on next reboot. Eventually, somebody figured
it out, because Linux started setting the dirty bit from gparted,
telling Windows to take a bash at it, after a gparted run
had made changes.

I don't know where else to look for documentation on this.
As long as I see reports from users that they're trying
hdparm or blockdev at partition (/dev/sda1) or device (/dev/sda)
level and things aren't improving, I'm left to wonder how
this really works.

There's the possibility of a slide switch, and perhaps
USB config space can report the position of any such switch.
But this behavior also smacks of something being written
into an MBR (or a PBR). But without documentation, we'll
never know. The Wikipedia entry for MBR doesn't have
any storage feature which is an exact match, just a copy
protect byte (not the same thing).

We had a flash device at work, and it had some sort of
per-page readonly status bit that could be set. The people
doing bringup on my processor board, managed to "spray"
the flash with read-only (the odd page was read-only,
others remained read-write), but they managed to figure
out how to restore full operation (somehow). That's just
an example of documentation at work. We know the devices
have some mechanism, because the "top" and "bottom" blocks
had a special status and could be made "persistent" and
readonly, so the bootstrap would never be lost. This
allows recovery of the device and makes it non-brickable.

Thanks, Guru Paul !!

Sounds more like a safety feature rather than a defective USB stick ?
Probably a good idea.

May try getting data out via data CD using Brasero.

GParted has a little key icon on my Ubuntu partition so I can not resize it
https://askubuntu.com/questions/473478/gparted-has-a-little-key-icon-on-my-ubuntu-partition-so-i-can-not-resize-it

For USB stick, selecting "Unmount" doesn't work. GParted crashes.

Interesting review of N550JV in the bad column "interior gets very hot
when pushed; " so I would hazard a guess that it is the fan and that the
thermal design for that laptop is not very good. I had a Del Latitude
D820 with nVidia GPU that was a good lap-toaster because Dell only put
one fan in that model when it really needed two.

Good thing the N550JX laptop has an Intel i7, which automatically shuts OFF if it gets too hot.
Hope I'm right about this. The laptop has not shut itself off yet.

GPU: NVIDIA GeForce GTX 950M (2GB DDR3)

The Intel processor has a GPU inside it.

Processor Graphics

Processor Graphics Intel HD Graphics 4600

So that would be a Bumblebee setup, when the
software loads.

The Intel GPU drives the LVDS cable
to the panel. When playing games, the NVidia GPU
copies the frame buffer somewhere, where the
4600 can play back the scan lines to the LVDS cable.
That might use 1GB/sec of main memory bandwidth,
for a shared memory that both the 950M and 4600
can see from a DMA perspective. The 2GB of private
memory the NVidia uses, is much faster than that.
So is the system memory. Faster.

That's a 26W GPU and a 45W CPU.

71W for one fan ? Might be a bit noisy.

The noise I hear does not sound normal (like a fan, even in high gear).
The noise comes on even when I'm in the BIOS.

May be dry bearings/sleeve of fan. peel off fan cover and put in a drop
of light weight fine oil. May also be vibration of loose fan mounts.

GKrellM shows CPU temperature is ~72.0 C.
https://i.postimg.cc/FzfqqxHN/Screenshot-gkrellm.png

Tried to open Thunderbird in old Ubuntu laptop to send image link (above).
Temperature shot up to ~100.0 C. Thunderbird can be such a CPU hog.
Got nervous. Killed Thunderbird from System Monitor.
Old Ubuntu laptop survived it though.

Turned ON the old Ubuntu laptop (without the optical drive) with the bottom panel OFF.
Can see fan spins fine but may be old and cranky. How difficult to replace the fan ?
Will disable optical drive in BIOS to take load off.
Will retire old OCZ Rally2 USB thumb drive.

As a test, old Ubuntu laptop downloaded large 1.6 GB Ubuntu ISO file.
Can't verify because the <blah>SUMS are for an older revision.
File size looks about right though.

72C is a bit high for an idle.

The 100C likely means the CPU is throttling at that point.
If your cooling system was completely broken, even throttling
would not bring down the temperature, and THERMTRIP would
turn off the machine at maybe 110-120C. 100C on the other hand,
is intended as the "peak long term temp". You can probably
run it that way for 100,000 hours (fan won't last that long).
The 100C is not a silicon limit, it's the limit of the
so-called "organic packaging" the CPU sits on. Back when
integrated circuits used ceramic packages, you could have had
the CPU run at 135C as the throttle point. But multilayer
ceramic packages are pretty expensive, and in the case of
modern CPUs, there wouldn't be enough contacts on the old
packages, to do a CPU. A lot of the electrical contacts
on a CPU, carry power, rather than signals.

Cooling failure:

1) Inlet or outlet vent blocked.
2) Fan rotation slower than normal
3) *No working fluid left in Heat Pipe*
4) Paste is bad (only a problem when end-users paste it)
5) Mount is no longer screwed down (unscrewed itself).
[Desktop plastic parts have snapped before.]

On a desktop, with six heatpipes in the cooling scheme,
you can lose a pipe (3) without anyone noticing. A laptop
on the other hand, typically does not have effective pipe
redundancy. A heatpipe which has lost the fluid,
does not cool very well at all.

When heat pipes came to the computer industry, initial
fabrication quality was poor. At least one product
arrived, with no working pipes (which means none of
the pipes had the two drops of fluid inside). This
gradually improved, as people stole the ideas for
sealing them. Today, you have a reasonable expectation,
of every pipe being in working condition.

The pressure inside a pipe doesn't have to be ambient.
A pipe could, on purpose, be at partial vacuum, or
could be up to a couple ATM, as this adjusts the
boiling point of the fluid. (No, it doesn't have to
boil to work, as the partial pressure of the gas
is sufficient to create thermal transport in the pipe.)

To repair a pipe, you'd find a replacement cooling
assembly from a junked machine. You should not use
an open flame near the pipe particularly, as the
working fluid can be a few drops of alcohol. While
water has been used in pipes, it's not the preferred
working fluid. An alcohol could have a slightly
lower freezing point, which might be a reason to
prefer it.

While we assume (most of the time), the problem is
(1) or (2), it could be (3) and that would be a lot
harder to diagnose.

CPUs where the silicon die is exposed, it's easier to
check that the paste is doing its job. On lidded
processors, sometimes the lid is not in good
thermal contact with the silicon. That's hard to
diagnose.

*******

You can pop a SHA1 into a Google search and see if any hits
come back. You might even find the page or file with the
SHA1 in it. When a Google search using a SHA1 returns no
hits, your download is bad :-)

You have to choose a checksum type, typical for the epoch.
Maybe a Ubuntu 8.04 CD would have used MD5 sums, in which
case you'd do an MD5 sum. Maybe a later DVD, the checksum
file used SHA1. Today, it might be SHA256 or even SHA512. The
method in the previous paragraph, assumes the operator knows
what epoch the media is from. Nobody would be using MD5
today for a "security" purpose, but an MD5 could still be
used as a download check. If you're worried about
"fraud" or someone planting media on a server, MD5 is
useless for that kind of issue.

Missing one
6) Poor initial design for cooling. Example my old Dell Latitude D820
with nVidia GPU, and just about every Apple product that I have ever had
the "pleasure" to work with.

I have a Thinkpad i7-2760 W520, an old but really good laptop (in the
day the most powerful workstation in laptop form factor).
The nVidia Server settings app tells me the throttling temperature is
127 degC and with a second (4K) screen it is regularly idling at about
90 degC.
With just the build-in screen it idles at about 75 degC, nothing to
worry about.
This is with several programs like Firefox, Thunderbird, Signal and
VeraCrypt open.
Shutting down Firefox (with some 100 tabs) doesn't change anything.

At idle after closing ALL apps except GKrellM,
I've seen it go as low as ~62.0 C.
I have not seen it go below that.

That noise comes and goes (even after completely removing the optical drive).
It had a good day yesterday.

For ubuntu-16.04.7-desktop-amd64.iso,
sha1sum generated is...
65fe391dd30949d62b381cdf12809f865f18d4d3

Doesn't seem like many people download that revision,
especially if the <>SUMS posted is for
ubuntu-16.04.6-desktop-amd64.iso

Blew more compressed air around fan area and
around the CPU/GPU and cooling pipes.

Tightened down ALL screws, none seems to be loose inside.

I use whatever <blah>SUMS files are provided...

But, it's useless if it's not for the revision automatically downloaded,
which most users do.
