My laptop is doing strange battery things; when plugged in and charging, it sometimes discharges anyway. Last Saturday it discharged to 0% and shut down when plugged in. Over the weekend I was unable to use my laptop; it spontaneously started charging again today.
One place this fault could be is in the power adapter. Will getting a new one fix my laptop problem?
Resolves YES if I buy a new power adapter and the fault does not visibly reoccur to me in the subsequent two weeks, resolves NO if I buy a new power adapter and it does, resolves N/A if I do not buy a new power adapter.
1,000@Tetraspace I just treated it like a low-likelihood-of-resolving market, given the high number of other things that could have been the cause on a non-cursory analysis
@Tetraspace Agreed with @PipFoweraker , no problem resolving N/A. In fact, if you've ruled out buying a power adaptor, people would probably appreciate resolving N/A now rather than waiting until market close.
I had to replace the power jack once. Found & bought the exact part the laptop manufacturer used, unscrewed the laptop, replaced it.
It could also be the battery: Your OS should have a tool to inspect the battery, maybe see if there's any obvious problem there.
It could also be the cable: Maybe you twist the cable around a lot, and the inside is damaged in a way that it only makes contact at certain angles. So you plug it in, see that it works, and then you move it a little and it stops working without you realizing until you're out of power.
Your power adapter might have a dimmer green status light if it has trouble delivering the same voltage. If it has the same brightness as when new, that's less likely to be the problem.
