Hi all,
Imagine the frustration when the laptop crashes & you dont know the reason?
Well mine's been happening a lot lately, atleast twice a day. It is going to
be a long post as I have tried as much as I could without taking the laptop
apart. So please provide suggestions after reading through the full post.
Thank you.
My specs are:
AMD sempron 2800
512 MB RAM
Combo drive
40 Gb hard disk etc etc.
The problem is, without warning, the laptop just POWERS OFF. It does NOT
shut down. Its like somebody suddenly removed the power to the laptop as I
mostly use the laptop without the battery. Initially I thought it could be a
power issue. But then I saw that it happens even when I am running on
battery. So I asked a technician to look into it and he said that it could be
a heat issue. So he cleaned everything and he said that there was a lot of
fluff blocking the air vents and close to the processor. Everything was fine
for a couple of weeks when it started again. This time he took the laptop
again and cleaned it and gave it back to me. But it has still hasn't solved
the problem. I also installed a 3 FAN system under the laptop with NO
difference.
Sometimes when I have switched it off all night and I turn it ON in the
morning, it does NOT get past the boot screen. It immediately powers OFF. I
have tried almost everything and nothing seems to work. When I go into event
viewer to see if there are any reported conflicts, there seems to be nothing
out of the ordinary.
When it powers off, if I try to turn it back ON immediately, it NEVER gets
past the boot screen. If I leave it for about half an hour and then try it,
it boots normally - which should indicate that it is a temperature problem. I
have now installed Everest Ultimate Edition and monitoring the temperature.
The CPU core temp never rises over 48 deg and the HDD temp never rises over
42 deg.
ember that before installing the EVEREST ultimate edition, I had installed a
program called "Speedfan" I think. It was giving me 4 temperature readings,
when EVEREST is giving me only 2. The 4 readings Speedfan gave me were: CPU,
HDD, ACPI1 and ACPI2. CPU and HDD were in 40s most of the time. ACPI (dont
remember which one among the two) was always in the 60s range. Although I
dont know if that has any connection to the problem as the laptop also
powered down after a cold boot (after leaving the system turned off all
night), when it did not even load Windows logo during startup. Immediately
after POST, it just hung for a few seconds and powered down.
Recently, I realised that the system powers down within a few seconds if I
enter BIOS. I also went into Acer tech support and downloaded the latest BIOS
and flashes it, but NO difference at all.
I then downloaded the EUROSOFT PC-CHECK software to see if there is
something wrong with the hardware. It is a bootable CD and as soon as it
boots into the CD, within few seconds, EVERYTIME it powers down.
I know that it is a very strange problem, making me think that the
motherboard is probably fried. Please somebody give me some assurance.
Anyway, if anyone has any other ideas, please let me know. I have to write
my thesis and I scared as hell to trust this laptop.
Thanks in advance for your help,
Sridhar
