my laptop power cable is pluged in and turned on but it fails to charge or power my laptop but its in properly and sumtimes works .. any help?
ok....this might not be you power supply cable.. this may be a problem with your powerjack in your laptop, if that's loose, then it won't recieve any power from the cable...it will randomly though..i had the same problem a few months ago, and a little solder job will do the trick! take it to a good local repair guy (or me if you're in the uk hahaha)... and have the power jack resoldered.. try your power supply on another similar laptop to make sure it's not that..but generally speaking..once a power supply's fried..it won't work randomly...all it is, is a transformer and a converter... it would make sense if it was the power jack loose or has a faulty connection to the motherboard :) hope this helped!
