Laptop won't boot up

The lights come on, but the display does not come on, and there is no fans/drives going.

I have tried taking the battery out and the mains out and leaving it for a few minutes, but that didn't work.

Any suggestions?

Thanks

Remove both battery and power supply. Press and hold the power on button for 30 seconds or so. Plug in the mains lead and try to power up. You may need to try this a couple of times holding the power button for up to a minute. If that fails I would suspect a motherboard failure.

This didn't solve the problem unfortunately. Whats the next thing to do?

Thanks

It could be anything. If the screen has failed you might try an external monitor but this is unlikely since you can`t hear any fans or Hard Drive activity. If the CPU fan has failed that could prevent the computer booting up as a safety feature. The power module might have failed or a serious motherboard failure.

What make and model is the laptop and how old is it? Your best bet is to take it to an expert laptop repairer and get them to assess it. Dismantling a laptop is not for the faint hearted and spare parts can cost a fortune relative to the cost of buying a new laptop. The biggest element of any repair is usually the labour cost, it can take a couple of hours to strip down, diagnose and rebuild a laptop.
