Laptop Suddenly Not Starting Up

  s99Raj 23:51 05 Sep 2009

I have an Acer Aspire 7000 laptop which has been working fine on Vista. A couple of days ago the screen suddenly went multi-coloured, with streaks of colours diagonally across the screen, and the only thing I could do to it was switch it off by holding down the power switch.

Now it won't come on. No beeps and absolutely nothing appears on the screen. Power is getting to the laptop, as the Power Button lights up and the Power LED also lights up. Pressing any button on the keyboard has no effect. I don't seem to hear the hard drive whirring. I've tried taking out the memory modules and hard drive but I still get no response from the laptop. I've tried connecting an external hard drive but that remains blank too. I've tried putting in a boot DVD but it won't boot from that.

What could be wrong? Processor? Motherboard? Anything else I can try to revive it?

You`ve pretty much done everything so it could be either of the things you suggested. Only one other thing to check - Remove battery and power lead. Press and hold the power button for about 45 seconds which will discharge the capacitors on the charging module. Plug back the power supply and try a boot up. (No need for the battery)

Is the main fan making any movement at all? If that`s packed up the laptop might not boot at all but usually it would perhaps start POST and then stop suddenly as the thermal switch cut in.

It might be the CMOS battery but I doubt it so personally I`d get it checked out at a local laptop repair specialist. Expect a nominal assessment fee but they should have the correct diagnosis equipment.

Can you enter the bios by repeatedly pressing F2 at power on? , if you can make sure D TO D (D2D) recovery is enabled. Acers have a recovery partition accessed by pressing ALT and F10 together immediately after power on.
If that's a no go, it's not looking good.

Might be worth asking here, dedicated Acer site,
