FUJITSU SIEMENS AMILO Li 1818
Well I came back from a 2 week fly drive to California this week. I was sorting out all my picture when there was a knock at the door my suitcase had arrive (another long story). I answered the door and came back to my laptop it had locked up. I switched it off and waited a couple of minutes. I switched it back on and nothing the screen was black.
The hard drive light is on and it spins for a couple of seconds. I removed the new battery and pressed the power button for a minute to drain any charge left in, still nothing. I plugged in my spare monitor just in case the LED screen had gone again and pressed Fn+F4 to switch screens, nothing.
I removed the CMOS battery and did a power drain, nothing. I removed the memory chip and cleaned connection (I don't have a spare memory chip), nothing. I removed the hard drive and put it in a caddy everything reads ok on WinXP. I did a backup of the WinRE factory install folder just in case I needed a new hard drive. I ran a Scandisk on a restart all ok.
So it looks like the motherboard is fooked. I'm using my new Windows 8 laptop at the moment which I hate.
I had a similar problem with my new Windows 8 laptop but I removed the battery and drain the system and it started up, nothing so simple here.
