Folks,
here's my situation and am wondering if anybody could provide some
suggestions.
Three weeks ago I had the motherboard of my Dell Precision M65 laptop
replaced due to issues with the video card. After the Dell tech replaced
the board I had no problems booting up on my F16 installation. After a few
days this motherboard started exhibiting power supply issues. The system
would switch from AC power to battery, dimming the monitor, and then switch
back to AC with the monitor brightening. This continued to happen on and
off for several weeks, it also would happen under Windows 7, so wasn't an
OS issue. I tried two different external power supplies, but the problem
still occurred. If I took the battery out and ran on just the AC then the
system would power itself off within a minute or two. I contacted Dell and
described the problem and today the Dell tech replaced the motherboard
again. The problem is that now Linux no longer boots. It starts to boot,
it loads the kernel and the ramdisk, but then the fan speeds up and the
system powers off. Earlier today I was able to boot off a F16 DVD and was
able to backup my user account data to an external drive. Now when I try
it it no longer works, it starts the process, I get prompted for language
and keyboard, but then again the fans speed up and the system powers off.
The system is configured to boot both Windows 7 and Linux. If I boot
Windows it comes up just fine and runs, but Linux wont. When I boot
Windows the fans do not speed up as they do with Linux.
Anybody have any ideas as to what might be going on?
The system is updated to the lasted changes. I tried to boot an earlier
kernel, but I get the same behavior.
Any help is appreciated.
Thanks,
Paolo

No $$$ out of pocket but what about your wasted time? Dell should be
glad you don't charge them for that.

I hope that you have some sort of record that the Dell tech told
you that the heat sink wasn't important. If he tries to charge
you anything for the repairs, you should take this to Dell, and
that record will keep it from being simply your word against his.
Fortunately this is all covered under warranty so nothing is coming
out of my pocket. I hate to have to pay for all this work.

Do you use an encrypted drive? That's one thing that would require
intensive CPU to decrypt, and one thing that Windows probably isn't
doing.
On my my older Fedora release, I do see something similar. When I boot
up, my laptop CPU rapidly gets *very* hot while just sitting there
waiting for me to enter the password to decrypt the drive. Dunno why
it's grinding its gears before it's actually doing the work.
No, it's not just the fan running at full speed, uncontrolled, it is
venting out hot air. Usually, there's just a slightly warm breeze being
vented.

I don't have an encrypted drive. But something is causing the fan to speed
up right before it powers off.

Check the inlets and outlets. The ones on laptops tend to get congested
with
dust.
Terry
All the filters have been cleaned. When the tech replaced the motherboard
he had to remove the heat sync. When he did this a piece of copper or
copper alloy fell off it's about an inch square. The tech said that it
was not necessary and did not replace it (fortunately I still have it). My
suspicion is that this component is needed.
I was able to get Windows 7 to power off as well. Linux does something
during boot that causes some device to overheat resulting in the system
powering off while Windows will boot up just fine. It's only when I try to
refresh the Windows Experience Index (Control Panel -> Performance
Information and Tools) that Windows exhibits the same power off problem
that I see in Linux.
I left a voice mail with the Dell tech.

The fan runs. It starts off low then speeds up considerably then the power
goes off. I'm suspecting either the video processor or the cpu is
overheating and this is causing the system to power off.

The fan runs. It starts off low then speeds up considerably then the power
goes off. I'm suspecting either the video processor or the cpu is

Download lots of different distros live CDs and try them.
If none of them work, bad motherboard might be a possibility.
(Or memory not plugged in all the way, or bad memory,
etc - always hard to guess for sure).
Did the OP check the bios settings? Something
may be set incorrectly?
Reset the BIOS if possible and set defaults. If that does not work, the
MB is most likely faulty, or something else (harddisk?) got toasted too.

This time it ran file system checks on the various file systems, but

after it started the relabel it powered off again.
Have you checked the CPU temperature? These symptoms sound like they
may indicate that the CPU is overheating.

The fact that letting it sit let it go further than before leads me to
believe that the battery was being more fully charged? I'd let it sit
overnight, and then try. :)
Terry
This might also be a problem with the power, going off of what you
mentioned about the fans for Linux vs the fans for Windows, it could
be a configuration FOR the motherboard that needs resetting, I've seen
laptops get FRIED from not having the power configured properly, and
on the other ensd of the spectrum, I've seen laptops not power up at
all, even though the battery was fully charged, and the power supply
was plugged in from the same power configureations not being correct.
Just something you might look into....

Have you tried fully charging the battery to full capacity? Some laptops
don't work off of the AC directly, but off the battery, which is cont'ly
charged by the AC. If the battery is at a low level, any requirement for
high current drain such as when doing cpu intensive tasks, can exceed the
battery's capabilities if it's not fresh.
Just my .02. YMMV. Good luck!

I let the system sit powered off for a while and then booted the F16 DVD and it booted
fine and mounted the file systems just fine. However, when I tried to boot off the disk
it got to the point of telling me it needed to do a selinux relabel and then powered off.
Paolo
At the Grub screen when booting off of the Hard Disk, add selinux=0 to the kernel line.
This will hopefully prevent the selinux relabel.

Download lots of different distros live CDs and try them.
If none of them work, bad motherboard might be a possibility.
(Or memory not plugged in all the way, or bad memory,
etc - always hard to guess for sure).

Are you sure your motherboard is the only thing that was damaged?
Regular unsteady power is bad for almost any kind of electronics. How
long does it stay up in Windows?

I can see at least two possibilities:
1) The F16 DVD is defective. I'd check it somewhere.
2) Your hardware is defective.
Beyond that I am not sure what to say at this point. Sorry...
Boris.
Boris,
the DVD isn't defective since it's what I used to install F16 on the hard
disk. I'm starting to believe I have another defective motherboard :-(

Wow, this is weird...
Have you tried reinstalling Linux? I know this is a crude approach to the
problem but I can't think of anything smarter at the moment.

Folks,
here's my situation and am wondering if anybody could provide some
suggestions.
Three weeks ago I had the motherboard of my Dell Precision M65 laptop
replaced due to issues with the video card. After the Dell tech replaced
the board I had no problems booting up on my F16 installation. After a few
days this motherboard started exhibiting power supply issues. The system
would switch from AC power to battery, dimming the monitor, and then switch
back to AC with the monitor brightening. This continued to happen on and
off for several weeks, it also would happen under Windows 7, so wasn't an
OS issue. I tried two different external power supplies, but the problem
still occurred. If I took the battery out and ran on just the AC then the
system would power itself off within a minute or two. I contacted Dell and
described the problem and today the Dell tech replaced the motherboard
again. The problem is that now Linux no longer boots. It starts to boot,
it loads the kernel and the ramdisk, but then the fan speeds up and the
system powers off. Earlier today I was able to boot off a F16 DVD and was
able to backup my user account data to an external drive. Now when I try
it it no longer works, it starts the process, I get prompted for language
and keyboard, but then again the fans speed up and the system powers off.
The system is configured to boot both Windows 7 and Linux. If I boot
Windows it comes up just fine and runs, but Linux wont. When I boot
Windows the fans do not speed up as they do with Linux.
Anybody have any ideas as to what might be going on?
The system is updated to the lasted changes. I tried to boot an earlier
kernel, but I get the same behavior.
Any help is appreciated.
Thanks,
Paolo

Sounds to me it is a BIOS bug. since it is a different board and this
board may contain a differnet BIOS revison, then
what was orginally installed.
Have you tried booting with the acpi off, something like acpi=off. I
had problems with acpi before with
different OS due to BIOS bugs.
I have not tried running with acpi=off. The version of the BIOS that's
present is the same as what was there before. I let it sit powered off for
a while and tried rebooting running just on battery, and this time it got
past where it failed previously. This time it ran file system checks on
the various file systems, but for some reason it also decided to do a
selinux relabel. Shortly after it started the relabel it powered off again.
