I have very unique problem with my Dell Latitude D610 laptop. It is 5 year old, since last few months, when I put my laptop to standby or sleep mode and after a while when I try to put on laptop, it does following:
1-laptop will turn off from standby/sleep mode and it won't turn back on no matter how many times I try, I have to remove battery, power adapter and leave the laptop for 10-20 minutes.
2-after 10-20 minutes when I turn the laptop on, a line will appear on the lcd screen and it will turn white and laptop crashes, this will happen 5-6 times, every time I turn the laptop turn on. after 5-7 times then laptop will turn back on fine and will work fine for next many hours until I put laptop back to standby/sleep mode or turn off completely off and when I turn back the laptop on it will shut-off, I have to wait for 10-20 minutes and screen will turn white and crashes....it will do the same pattern and eventually turn on fine.
This is what I had done to correct the problem:
1-i clean the laptop with dust-off including fan entire laptop if there is heating problem
2-updated most drivers including display etc
3-used external monitor to check for LCD problem, no apparent problem with LCD as when lcd turns white laptop crashes too?
4-use external laptop cooling pad to keep the temp down, use mobile meter software to monitor laptop hdd temp?
I tried everything I could think of?can anyone suggest anything else?in my opinion this is a faulty mother board problem or video graphic card?please help if you can-Thanks
