MUHAMMAD WAQAS, in order to answer your question I would need a little clarification. Please reply if your question means, your computer was shut down automatically after you left it for 12 minutes unused in the night and it won't power on now.
I have the same problem with my dell 5010!
Last night I used the laptop and the battery discharged and the laptop was turned off!
after that when I plugged the laptop to AC power the orange Charge Led was blinking 3 times.
i removed the battery and unplugged the charger and held the power key for 30 seconds to discharge the capacitors .
after that I re-inserted the battery and plugged the ac adapter.
when I pushed the power key, the power led was turned on and the fan speed up and it was feasible to open the DVD tray when pushing the open key. and I heard 4 beeps.
i removed the ram and turned it on and I heard 2 beeps.
i also connected it an external monitor using a VGA blue cable.
but nothing was posted on start-up .
whats the problem?
can you help me to fix it?
4 beeps at start-up on "Inspiron N5010" indicate Memory read/write failure. Correctly you removed the memory sticks for this situation. 2 beeps after removing Memory cards indicate No Memory (RAM) detected, which is normal. Next step is to try one memory module at a time in each slot. Did you try this? If yes, what was the result when trying the combination of memory modules in different slots?
