My laptop's bottom gets extremely hot even when idling.

I can hear the laptop turning on but the screen doesn't come on?

My computer will only boot when I have the cord plugged in.

If this is the case you might want to try to blow out the cooling vent found on the left side of the laptop. You can find compressed air at places like Office Depot, Staples, or Amazon. If worse comes to worse you can attempt to blow the vent out manually. If the problem persists we have a guide on how to gain access to the CPU fan here.

There are a few things that you can do. We've included a few in our troubleshooting page. Hopefully one will work in your case.

It may be that the battery needs to be replaced. Sometimes your battery just decides to give up.
