Fix Computers

1st thing to do is check if laptop fan and fins are clogged up with dust which are preventing it from spinning, then look at above suggestions

1st step is buy some hinges which you can get of ebay, buy a pair and replace both. The price for a pair of hinges is around £20-£30. 1. Remove rubber grommets from around laptop screen. 2. Remove all screws from laptop screen bezel. 3. Gently prize off laptop screen bezel. 4. Remove screws froms hinges and detach hinges from screen. 5. Replace hinges

I would say the first place to check is the for a build up dust in fan and air vents (fins).

Ebay is always the first place to start, see link below Dell Adamo Motherboard

Replacing the DC jack on a laptop can easy or hard, easy when it does not need to be soldered in, hard when it has to be soldered. In your case a new DC jack needs to be soldered so the best thing to do is let an expert fix it. My laptop repair business based in Manchester would charge you £55 to replace a DC Jack which is a very competitive price, so use that price when phoning round for quotes, good luck

I like revo uninstaller for removing software, very good.
