My laptop power off after 5 min under MSDOS .. Why ?

[verspieren]

Hi,

Why my laptop is shutting off autmatically under MSDOS but not under Windows ?

I'm able to use it under windows as long as i want with no trouble but if i want to boot under dos (ie: to ghost it) the pc shuts down after a copple of minutes.

There is no link between ghost. i tried to boot and to do nothing else ... same problem !!

Could you help me ?

Many thanks for your help.
Regards.

How are you booting to DOS?

Overheating? Can you check the CPU temp in the BIOS?

Turn off power management in the BIOS - there may be some kind of issue there?

stduc is right (as his wife ) . If you can not disable the power management in the BIOS then you won't be able to avoid the problem.

Just work faster...

Seriously, I would not give up until I've peered into every corner of the BIOS for anything pertaining to MS-DOS or default timeout. The BIOS is doing its job, handing off the ball to the OS. For some reason, it does not see MS-DOS as an OS, and then it timeouts. If there is a timeout it seems it should be adjustable or defeat-able somewhere. Just a ray of hope...the eternal optimist.

Does the laptop feel as if it's hotter when running in DOS? Running certain DOS programmes appears to make the CPU run hotter. I suggest you check the CPU fan, air vents, and heatsink for partial dust and dirt blockages. You might even consider rechecking the seating of the heatsink on the CPU - clean off the old compound and apply some fresh, like Artic Silver.
