My Asus X553M laptop is not booting up. Any ideas how to fix this problem?


Temitope, Hard reset. Open computer, remove battery,hold power button down (((1 minute))), reinsert battery, reassemble laptop, push/hold power button a couple seconds.
2nd fix, try to boot laptop without hdd.(hard drive). Remove the hdd, then turn on the laptop.. then it can get into the bios.. reset the bios to the default setting, turn off the laptop, and then turn it on again with hdd reinstalled. This seems to be what works in the forums with this issue found in Asus laptops. Check the attached links,instruction and guides, Good luck

The laptop needed charging. After charging, when the power button was pushed, the screen remained black. The power button is lit. What is the problem?


Sometimes when you reset the computer, that happens. disconnect the AC and count to 10. Plug back in. If that doesn't work...turn on from the power and that should automatically reset the screen.

It is the backlight! That laptop uses a fluorescent lamp. It is bad.
If you look carefully at the screen, you will see the Windows desktop (or whatebver you are running). It just needs to be lit up.... from the back. Tel them to replace the LCd screen or replace the lamp.

Hope this helps!
