How to fix may laptop
Screen flickering when charging but ok when unplug
Can you try using a different, known working compatible charger and check if the problem is still there?
If you can't try another charger, if you have a DMM (digital multimeter) check if there's a steady 19V DC on the output plug of the charger. This is just to check whether the problem is in the charger - AC ripple effect on the DC output i.e. varying DC voltage shown on the meter, or a problem on the motherboard's power management circuit.
If the charger is OK then you may need the schematics for the motherboard. I can't find a free download online but here's a supplier that isn't too expensive.
