I have big problem with my ASUS X551M, but I need a computer right now,its really important for me.
I am an engeneer,so I would like help at an engeneer level.
My laptop simply won't turn on. LED indicator for charging works, sa as the green signal LED that turns on when I press the POWER button. Its allright. And the DVD device works:if I put media in it and press the power button it roll it up,you can hear the sound of head positioning. BUT DISPLAY STAYS APSOLUTELY BLACK,NOT EVEN A LOGO,NOTHING HAPPENS.
I did all ussual steps,resseting CMOS,clearing the condenser,it didn't work.
Help,please.

Hi,

Please do try these troubleshooting steps that may help.
- First is to do a hard reboot, remove the battery and unplug the AC adapter then press and hold the power button for 20 seconds then try booting it up again.
- If it will still load into a blank black screen connect an external monitor and see if you'll get any display from it. If there's a display on the external monitor that could mean that the problem lies in the built in display. If you can, open the laptop and check the ribbon cable that connects the LCD to the motherboard.
- If there's still no display on the external monitor you'll need to reseat the RAMs', turn the laptop completely off and unplug it from its AC adapter then remove all the RAM's off then put them back in making sure everything is seated properly.
- If reseating the RAM's will not work then the problem is the motherboard.

Here's a video guide on how to disassemble your laptop.

"I did all usual steps,resseting CMOS, clearing the condenser, it didn't work" How did you manage to clear the cmos on a laptop, and wtf is a condenser?
