Laptop isn't turning on

Hello, I have a couple questions:

I am working on a Gateway M305CRV laptop. It will not turn on. When plugged into the wall, the LED light does not come on even indicating that it is getting power. However, the power cord does light its own little green LED light on the box halfway between the wall and the computer. When I push the power button on the computer, nothing happens.

I know my battery is poor. If the battery is completely dead, can the laptop still be powered on by being plugged in?

What are the first few steps I need to take to analyze this problem further?

Thanks for any help you can provide!

 

Have you tried removing the battery then try turning it on using just the power cord?

 

Yes I have....that does not work. =\

 

HI beta7

Might you have lost the “power wire” of your "turn on" button ... check if it has not burnt out with some bad light performance...

Regards

 

Try wiggling the power cord (especially on the laptop side) and see if you can start up the computer. Even if the battery is bad the laptop should run off the ac adapter (power cord).

 

The problem could be a AC power port or worse the PSU of your laptop.

 

Well I have recently noticed that when I plug my laptop into the wall, I notice a very faint hissing noise coming from within. This probably isn't good. Any suggestions?

 

Probably that is a short circuit from your laptop....Better have it check there could be a loose contact.

 

hey, I had a similar problem with an HP. When you plug the adapter into the laptop, do you notice any wiggling of that adapter head, particularly some that you haven't noticed before? If you do experience some wiggling, it could be that there is a loose connection between the DC port and the circuitboard which it is connected to. Usually the DC socket can be re-soldered to resolve the issue, but of course this breaks warranty

 

Well, I'm well out of warranty, so its worth a shot.

I am fairly knowledgeable when it comes to computers, but not so much with a laptop. Does anyone know any good reference websites for taking one apart?

Thanks for the help everyone.

 

Beta, I am experiencing exactly the same problem with my Gateway 6442. After trying all the suggestions, plugging and unplugging, removing battery and long start holds I am about to send it to Gateway and then to the dumpster if they say it is fried. This sucker was exactly one week out of warranty. I will try the internal batter (if I can find it) first. Good luck. Ten
