Laptop charges for a few seconds, then says not charging, starts charging again

HP ProBook 450 G1
Microsoft Windows 10 (64-bit)

Hello!

A few years ago I bought a HP ProBook 450G1 and I've been using it for a while. Last month I had to get it fixed because it wouldn't turn on, somethings were damaged by a faulty charger. Since then, I bought a new charger (Hama, universal charger) and the voltage matches the original one.

Since I got my laptop back from the service, I have this problem: when it's plugged in, it charges for a few seconds and then it says "Plugged in, not charging" and after a bit more time it starts charging again. The battery level stays the same. I've never changed my battery.

I have also tried reinstalling the ACPI-Compliant Contro Method Battery from Device Manager. I have also tried unplugging the charger, removing the battery and all the peripherals and afterwards holding the power button for 20-40seconds. I updated the BIOS aswell, I got the update from HP website. The problem was there before the update, and it still appears.

Please note that if I remove my battery, but the laptop is still plugged in, it will shut down after some seconds.

Is the battery original? The knee-jerk here is to blame the "universal" adapter. Have you tried the diagnostics on the battery by tapping esc or F2 as you power up?

My battery is original. The only battery diagnostic I have tried is the one offered by HP in their "HP Support Assistant" program. I will look for that diagnostic and I will reply soon. Thank you!

 

EDIT: I have checked the startup menu (Escape key) and there was no battery diagnostic, only System and memory diagnostics. Could my problem have anything to do with the fact that I enabled Hybrid Graphics in BIOS?

UPDATE: I have gone back to BIOS to try and find something that might help, but instead I stumbled upon a few settings which I think might have something to do with the battery, but I'm no expert. Here's what i found:

1. Boot Options -> Require acknowledgement of battery errors (is turned off)

2. Built-in device options -> Boost Converter (is turned on)

Your system might predate UEFI diagnostics or just not have it installed so F2 might not provide a diagnostic option. What does the HP Support battery test say? My thought right now is you just need a new battery and we are guilding the lilly and ignoring the obvious here.
