Each time I insert the power cable into my laptop ,it turns on for like a second then it goes off.My assumption was that its BIOS was the issue ,but still I tried troubleshooting that problem with the interim solution for safe mode booting (Holding the power key for 15-30 seconds then afterwards pressing the windows key + B simultaneously ) but the fan just kept on running but nothing was displayed on my screen.Then I had to restart all over again but still nothing was solved .Kindly assist me ,thank you.
Sounds like it is running, just your display isn't.
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.
