hi experts i am using dell latitude d800 suddenly the screen hanged for many minutes so restarted manually, than onwards screen is blank even after power and fan in working conditions, so i done experts opinion of removal battery and holding power button and again AC connected . than it worked but after few minutes same screen hang and screen blank at next reboot. what to do?????
 
Could be a bad motherboard. Try different RAM and working without the battery see if that helps at all. Aside from that you need to start testing hardware like the motherboard, sometimes a bad hard drive can cause a crash and inability to boot also.
 


thank you... it worked today and run in safe mode but after 20minutes screen becomes unclear hanging started and again same black screen at next reboot???
 
Did you check with an external monitor? LCD could be bad. If an external monitor also does not work, it's likely a motherboard issues but you can test different RAM first to rule that out.
