The power connector feels firm, but I hear the unplug-plug-in sound frequently - sometimes more than once a second. When that happens, the battery discharges as if it wasn’t plugged in, despite the LED being green and the icon at the top of the screen indicating that it is charging.
Sometimes I can use the laptop for hours without problems, and sometimes I have the issue described above. Sometimes actually unplugging and re-plugging the device will solve the problem for a while, sometimes it doesn’t help at all.
Today the screen suddenly went black, and the fans started whirring on overdrive. After about 15 mins the laptop went to sleep, and I could wake it like normal. This might or might not be connected to the above issue. However, it prompted me to have a look at syslog, and I found a ton of these messages:

… on and on, over and over again. I know very little about the internal workings of Linux, but some online searching made me assume that this could be connected to the plug-unplug issue. Thought I’d mention it just to be sure.
My best guess is that there’s a loose connector somewhere, or maybe a problem with the cable. Is there anything I could try to confirm/exclude that? Or anything I could try to solve the problem?
