I'm having a problem with my HP laptop, and I'm not really sure if it is a OS problem, but rather a hardware one. First of all the laptop model is HP 15-db1100nm. Most of the time my laptop has been plugged in, I rarely use it only on battery power. But now I need to do some work only on battery power, and the OS keeps crashing when it is unplugged. But this isn't always the case, sometimes it works fine and sometimes not. When I say crash I mean the screen just goes black and I can't do anything, but to hold down the power button and shut it down. It usually happens when there is some load, most of the time web browsers make that happen. To be more precise the only programs which led to this behavior are Chrome, Firefox and TeamViewer, but I kinda think that other programs might aswell do the same thing. Sometimes it works just fine even when these programs are running.
So what I've done so far is that I checked my battery status with
upower -i /org/freedesktop/UPower/devices/battery_BAT1
and the result was:
vendor: Hewlett-Packard

Because I thought it might be a OS problem, I was running XUbuntu 18.04, I did a clean install of Ubuntu 18.04 (I'm not going for the 20.04 LTS version because I can't get the WI-FI adapter to work).
About a year ago I was using Windows 10 on the same laptop, and it kept crashing for some strange reasons no matter if it was plugged in or not. Xubuntu was crashing when plugged in aswell but only when it tried to go to sleep etc. When I disabled those options it stopped.
A few months ago I've added one more 8GB RAM module and that's all the hardware modifications I've done. If it matters it is a 3200MHz module, but runs on 2400MHz as it is the limit.
I tried to check CPU temperature, but couldn't detect any sensors with sudo sensors-detect.
I suspect it is a hardware problem but am really not sure. I'd appreciate any help. I'll probably go to some technician, but currently I have no time and I really need my laptop.
Thanks in advance.
