Hi all
I have a notebook pc that keeps switching itself off when booting more than
once.
It will boot fine first time and have run for hours but, if I re-start when
the machine is warm (anything within 2 hours) then it starts to boot and
then switches off as if the battery is dead (but it's on mains).
I did think it was a mobo problem but was advised that it would turn off
when hot if it was faulty and not just on booting up. I have replaced the
ram and hard drive but it still happens.
Can anyone offer some advice?
TIA

Look in the bios and se what the cpu temp is. There may be an option to shut
down once it reaches a certain temp. You can usually change that too a
higher temp to stop it from shutting down.

Hi,

It sounds like a heating problem. It is likely that there could be a lot of
dirt and debris blocking air flow. How old is it? Are the vents all clear?
The only way to really be able to clean it completely is to break it down.
If you have never broken a laptop down before, read up a little on it first.
Try to locate as many diagrams and schems for your model as you can. If
possible, try to locate a service manual. Google to see if anyone else has
broken this model down before. Laptops have a lot of proprietary components
and sometimes breaking down the case and chassis can be tricky.

Use a clean workbench with a lot of lighting. Write notes about anything
that you could possibly forget how it goes back together later. Even take
pictures with a digital camera as you break it down for later reference.
 
hi
It is a common problem when a computer reaches 60 degree to 80 degree
centigrade
What you need to do is to use your notebook pc directly opposite a
standing fan or in a air conditioned run. That will solve your problem
with your notebook restarting after a long usage.

I think the fan in mine stopped turning completely.
Gotta' take it apart and see what goes (or doesn't go).
The last time, the fan was sitting on the bottom of the case.
Fell right out of where it's supposed to be held in place by magnets.
Ain't supposed to happen, but ....

Hi
Thanks for the reply. I have tried that and it didn't help. As a test, I
have run it for 48hrs with no problem. But, if I click on restart, it starts
to re-boot and then turns off. I'd have thought if it was a heating problem,
it would just turn off after 'x' hours of use.
Thanks,
Subs

No, it won't. It may work for a PC with the side panel removed, but
unless you've completely disassembled the notebook PC you will not have
any luck with these recommendations.

As others have already posted, it'd be a good idea to try and download a
copy of the maintenance and repair manual for your notebook and
carefully clean it out and make sure the fans aren't all gummed up.

Regards,

Ari
