Re: Laptop powers off at random


Newegg.com has 256MB PC133 for around $38 so it's not expensive online.

This sounds like an overheating problem more than memory and I would
suggest the following first before buying memory -

First - (if it has one which most hsf on laptops do) removing the
thermal pad on the hsf and using some thermal compound and see if it
helps any. Just because the laptop does not "feel" warm or hot does
not mean the cpu is not cooking to death. If the heat from the core is
not transfering to the heat sink material it will overheat without the
rest of the system getting warm. Being a celery 1.13 the laptop should
feel warm especially on the base and keyboard near the processor
because they generate good amounts of heat and everyone I work on is
very warm if transfering heat correctly. The whole laptop acts like a
heatsink in a way on some models.

Second thing is check to see if the MB is cycling the fan. If not this
could be a bad fan, pad thermal probe or a needed bios update. Also
blow out any dust or debree that might be hindering cooling.

Third - Memory, if it is flaky, will cause weird errors and BSD's more
often than just a simple shut-down. I don't believe the memory is the
cause, but you might reseat the simms to check.

Fourth - All mobile Pentium III and Celeron mPGA, uPGA and MMC-2
processors have "speedstep" which is intel's speed throttle built into
the cpu for battery life. When the laptop is on battery power speedstep
runs the processor much slower, usually around 700mhz for a 1.13 and
decreased voltage, and thus causes less heat buildup from the processor
core. This would explain why you say the system works better with the
battery alone.

Hope this helps!
