Hi, i have a Lenovo laptop. I can not turn it on.
I have tried different AC adapters, removing battery, doing hard reset of power, removing HDD, removing one of the RAMs or both, removing and changing the CMOS battery.

But still same problem.

When i plug AC adapter in, it will automatically start (no power button pressing), but there is only black screen, CPU fan spinning and noise in DVD drive. Thats all.


I need help, because i do not know what to do.

Also tried connecting external monitor, all peripherals are disconnected and cleaned it with air.

Thanks in advance
 
If you connected an external monitor, while using the following steps, and it showed nothing as well, then you may well have a fried GPU.

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.

You may also want to try hitting CTRL + SHIFT + WIN + B to try and reset your graphics driver as another possible fix.
