My laptop is Acer Aspire 1801. with 17inch screen.
Uses Windows.XP.
It started beeping intermittently and worked for about 20 minutes then powered off.
Now the power light comes on for a splitsecond only and the laptop has stopped functioning.

The machine is 3 years old with very light usage.

I would appreciate any advice to get it working again.

Welcome to BC

My guess, and this is only a guess without looking at it, is you had a bad CPU fan and it was overheating
It sounds like you might have finally toasted the CPU

There are usually many possible reasons for what you describe.

One is a build-up of dust internally causing quick overheat, even CPU failure as the last post suggests.
It could also be a memory failure too. It doesnt matter how much its used (you said light use) if you use it poorly.

Many with laptops use them on their beds or other soft furnishings to prevent them burning their legs as they warm up! If the vents are blocked then the machine doesnt cool properly leading eventually to a hardware failure, which is what the beeps would suggest.

Its hard to say without knowing how its used.

3 Nov,2009. Thank you 'garmanma' for your reply.
The computer started this morning with the Power switch LED light blinking on and off all the time and the beeping noise intermittently every 15 seconds.
When the computer program XP finished firing up I then closed down in the normal manner perfectly after about five minutes from powering on to powering off.
I opened up the laptop and looked at the CPU and it did not evidence anything unusual and all the fans are working.
If you have any further advice on the malfunction it would be appreciated. Many thanks.

Hi Cotesy,
Thanks for your reply. I have cleaned the dust out of the main fans and the vents including the large ones around the cpu.
Even examined the cpu and replaced it after coating fresh white compound on the heatsink, it looks OK.
The memory looks OK. I started the computer this morning and it opened up normally apart from the Power switch LED blinking and a consistent 'beep' every 15 seconds.
When Windows XP fired up I was able to close down in the normal manner not wishing to risk more serious damage by keeping it going too long and overheating.
It is used on my desk a flat wood surface so ventilation should be OK, and I noticed all fans were turning when it was on.
I would be pleased If you can offer any further observations

Hi again,

Try downloading Everest onto your machine from here - http://download.cnet.com/Everest-Ultimate-...4-10499291.html - Once run it will give you temperature readings on your taskbar whilst it remains loaded - If its looks like its getting too hot then this will confirm it.

You say the machine boots up fine, does the beep continue all this time?
