I have an old HP Mini 210 that is not charging properly. When I plug the PSU into the laptop I have to arrange it just right for it to power the laptop (or so I think.) I have tested this with two PSUs.
I disassembled the laptop to get to the PSU plug, which is attached via a 4pin connector to the MB.
When I test the the PSU directly at the male end, I get the proper 19v. When I plug it into the female end, but do not connect the 4pin to the MB, I get 19v. When I plug it in to the MB that power drops to 2v - 3v.
When I connect the battery the LED flashes but then stays dark. If the battery was fully powered it would be white, if the battery was charging it would be orange.
I have tested this with 2 PSU (although one male plug, spliced on to the 2nd PSU.) Both PSUs are rated for this laptop.
My thought is to buy a new MB, but any advice would be appreciated.
