I am having problems with my laptop's power supply powering my computer and charging the battery.
It loses the connection seemingly for no reason at random times. I restore the connection by unplugging the DC plug from the computer and plugging it back in. So far I have tried jiggling and rotating the plug, moving the cable, and inspecting it for sharp bends or loose connections around the transformer. They all seem to have no effect on my connection, as doing these things neither breaks nor re-establishes a connection.
I have tested the power supply with a multimeter, and it consistently supplies the correct voltage. I have not been able to test current, so it seems possible to me that there is a deficiency there.
There doesn't seem to be any rhyme or reason to when the problem starts acting up. At times I can move my computer around with no problems - pick it up, put it on my lap, put it back on the table - all without disrupting my connection. Then at other times it starts acting up without any physical disturbance at all - it just loses the connection out of the blue without moving the computer or the cord. Many times I don't notice this until my battery has run down and the computer hibernates. It's getting really annoying.
I have also opened up the computer to try to inspect the solder connections where the DC power jack connects to the motherboard. Admittedly I was not able to disassemble it enough to get a great look at it. I don't think I have enough expertise to go any further than I did. From what I saw though, the solder connections did not look broken or burnt, and the fact that jiggling the plug when it's connected doesn't have an effect seems to me to point to the problem not being a broken solder connection.
Does anybody have any advice? I wish I could just chuck this thing and get a new laptop.
