Windows 7: Compaq laptop "plugged in, not charging"

Compaq laptop "plugged in, not charging"

I bought a new adapter (universal, 9.5V-24V) and set it on 18.5V like my original charger was. It worked for a while and then stopped charging (although it still powers the computer). So I tried uninstalling Microsoft ACPI-Compliant Control Method Battery from the Device Manager and rebooted, nothing happened. Eventually I got it charging again when I set it on 19V, but now it seems to decide it doesn't always want to charge it like that either. So now, when it stops, I either take out my battery and put it back in (does not always work) or differentiate between 18.5V and 19V.
Is there a possibility that Compaq has a fail-safe against using third-party chargers? Or could it be a software malfunction somewhere? I'd like to try everything before I go buying a new battery/charger.
Before you ask, I have charged my comp with a Dell charger and it worked (then again it was only once so I don't know about what it'd do in the long run).

Does is says "plugged in, not charging" when battery is at 100% or around 100% like 80-90%.
Because its normal for laptop to turn off charging when battery is nearly full to let it discharge for a bit and then turn on charging again.
If battery isn't charged when it drops low for example 50-60% or lower then its a problem.

It doesn't matter what percentage it's at. It does it even with just 7%.

Hi blandade,

This is the reason it is always suggested to buy the AC adapter from the OEMs only. If this issue keeps occurring then you should check with a compatible charger provided by the system manufacturer only.

If the issue occurs with the genuine OEM charger as well then it could be a fault with the power port on the system.

Kindly update your system specs here by following this.

Keep us posted with the results so we can advise you further.
