Hi guys,
I m new here and need help diagnosing a laptop that wont start(boot?). It happened today, i was using it then put it to sleep for a while and when i tried ti wake it up the fan started like usually, the lights blink(power indicator, wireless key, tab key) but the screen stays black all the time.
What I tried:
1) Shut it down by holding the power key for a while, powered it back the same thing, black screen, lights on/blink..
2) i suspected a boot problem because i dual boot lubuntu and windows so i puled my win 7 cd and tried to boot from it, same as above. Tried to boot from USB flash drive( i got lubuntu on it), no change.
3) removed the battery, unpluged the power cord, held the power on button for 3 minutes, pluged the battery and cord back in. The same thing again.
4) i don t know if this matters but i connected this moble device in a usb port and it started charging normally.
Some other things i noticed that might be(or not) related with the problem a kind of "knack " sound on the left hinge of the display(can t say for sure it started today though) and i can t hear a light grinding of the haed drive as could be heared when it was starting after shutdown (there was no such grinding sound when it woke up from sleep though).
My laptop is a Compaq pressario CQ56 V140.
Any reply appreciated. Thank you.
