It has to be held to the one side now, what can I do about this? Could I fix it? Or how do I go about replacing it?
Is your laptop still under warranty? If so they'll usually fix it for free, usually just with a replacement cord. I'm not sure about fixing it. Someone else will have to chime in for that. If all else fails, if it is a common brand you could always just ebay a new one or get a generic one, though the generic ones are hit and miss.
@Ben_H: It's a four year old laptop so no warranty, but the issue is finding the right cord is it not?
@big_jon: Yeah, the main things you would have to worry about in finding a replacement is the wattage (it should say on the power brick part of the cord. It'll say like 60W or 90W or something) and the connector end that plugs right into the laptops. Most generic laptop chargers you can buy actually come with a whole bunch of connectors that fit a bunch of different brands of laptops. The connectors just fit on the end of the cord. If you have a major brand of laptop (HP, Toshiba, Asus, etc.) there should definitely be one that fits your machine.
The other option you have is to find the part number for the charger (it might be on the actual charger itself or you can just look up your laptop online and you should be able to find it) and see if you can find a place selling the exact cord. Ebay works wonders for that kind of stuff or some type of part supplier store.
@Ben_H: Thanks a lot, I'll definitely do that.
@Ben_H: Update, thanks for the advice, ordered one off ebay, seems to be working fine.
@big_jon: Hey, no problem. Happy to help.
