I cant power up my m-7301u laptop. It seems like the recharger is not working

try using a different charger if its not that then its a problem with the connection part of the computer

SATA is standard so if you purchased an Sata Power Cable from anywhere it should work. One end will only fit into the back of the hard drive and the other end will only fit into the slot on the motherboard.

clean your fan with air spray

My guess would be the backlight. The inverter can easily survie the fall. If the Lid Switch there won't an image.

Unfortunately your battery is probably shot. First though, try to run the battery down until the laptop dies. Now with the discharged battery, and the laptop powered off, plug it in and leave it off for a few hours. Power the laptop back on and check the charge level. Still at 30%? Then the battery is very likely just bad. Unfortunately, the cells in the battery just simply die for a number of reasons, and capacity is lost. This is why most manufactures will only warranty a battery for 1 year.

Take the battery out and write down the model number and the "MAh" or "Ah" number. The MAh number represents the capacity of the battery. The higher this number, the generally longer the laptop runs on battery. Go to http://gateway.shopbysystem.com/gateway-m-7301u-notebook-accessories.html and verify that this is your laptop model. This is a Gateway authorized reseller. Looks like they want $90 for a small battery. Take your battery model number and go to Amazon and look up the battery there. Make sure it's MAh number matches or exceeds what is on your battery. Usually you can get a replacement battery from Amazon for about $20 less than Gateway.

I have not heard of known issues. My suggestion is, if you are sure the MB has gone bad, is to look on E-bay to find a replacement. The price will be way better than going to the manufacturer.

this worked for me

1. Power down your PC
2. Remove the screws from underneath your pc (don't be affraid this is easier than you think!)
3. Be very careful with the flat ribbon cables as the are very fragile, locate your cmos battery
4. 
5. Remove the battery as illustrated in the above image -- This wil clear the bios password.

Hope this works for you.
