Screen turns on and off repeatedly not allowing me to use the laptop
After a minor accident, the power button of my laptop screen got pushed in. I was unable to turn on my laptop but it was charging. So, I got it fixed from a local computer repair place. They said the switch as missing and replaced it with a Travelmate switch they had. It was sort of precariously put back in place but at least I was able to turn on and use my laptop. But after a few weeks of irregular use, the outside button started to slip in and I was unable to turn it back on. After pushing the button a little more, the laptop screen lit up with a dull black colour and went back off in 2 seconds. This is my problem right now. The screen simply keeps lighting u (dull black) and turns off repeatedly with a gap of abut 5 seconds. Unable to make it work or turn it on. Can you help me identify the problem?
