Lenovo G40 won't turn on.

2018-03-30, 10:49 AM

Hi guys, my Lenovo G40 suddenly won't turn on. The power light is lit, however the monitor only shows black that is twitching from black to gray and just repeats doing so. Please help. What seems to be the problem? I also tried doing the basic troubleshooting steps such as removing the battery and pressing the power button for a minute. But still the issue continues.

Try using an external monitor to see if it shows BIOS / Boot Screen from OS loading, or even the desktop. If second screen does not show different, then you can try some additional steps such as remove and re-install memory sticks, try booting from USB without HDD installed, removing DVD drive to see if it boots without it installed.

Those steps will help determine if it is a system failure or a component issue.

Good luck.
