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

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.
