Laptop won't turn on

[chastephen1]

My laptop won't turn on. Maybe it's on but my monitor is all black. And when I force it to shut down by click'n'hold my power button. But then when I power it on back 2 seconds later it goes to sleep mode. No boot animation or anything. But nothing. It goes to sleep mode. I'm not that certain if it's sleep mode but it flickers on'n'off. What should I do? And before that, my USB port won't work. I fixed it by updating them but they are updated!! What the efffff!!? What should I do?? Need help pleeeeeaaase!

If it is on, but nothing on the screen, try this...

1. Turn the laptop off (not sleep or hibernate but off).
2. Connect an external monitor to the laptop.
3. Turn on the external monitor.
4. Turn on the laptop.

NOTE: You may have to press an "external monitor" button. Could be the f4 button or a button with two monitors on it, for the external monitor to work.

If you can see fine on the external monitor, then your attached display, or the ribbon cable that connects it, are your problem.

If you can't see on the external monitor at all, or the problem occurs on the external monitor as well, then it is probably the graphics card/GPU that is the problem, which may require the motherboard be replaced.

In regard to the USB port, did you go into "Control Panel" and then "Device Manager". Locate the "Universal Serial Bus controllers" section then right click on it and choose "Scan for hardware changes".
