Omen laptop will only charge when switched off

[Stokeparker]

When trying to use my laptop today, I found it would not charge. When I switched off whilst plugged in, it charged fine, but as soon as I switched it on it stopped. Everything was working perfectly yesterday.

I have tried several remedies suggested on forums, but nothing has worked. On this model it is not possible to remove the battery, so I cannot check if it will run on the mains power as some articles suggest. I have deleted and reinstalled the battery drivers, and updated the driver chipset as suggested. I could not update the bios as it stops halfway through and tells me I need to connect to an external power source, which is the whole problem. I have also tried it with another charger, which did not work. 

The computer is 6 months old and in daily use, so I seriously need to get this fixed. Any suggestions greatly appreciated.

@Stokeparker I suggest you start with a hard reset: Click here for steps,

When done, you may want to check with an alternate power cord/adapter as it could be a malfunction that's causing this issue to occur, here's what you could do:

If the charger shows inconsistent power output values, I would suggest that you step into Best Buy or staples and try with a different adapter and that should isolate the issue to the adapter or the computer.

Please try a different battery on the unit as well. 

Do not buy the battery and adapter. It is only for testing.

Use spare ones that they may have. If it works correctly, then you could think of buying it.

Meanwhile, also, try the below:

Steps to uninstall the ACPI drivers

Right-Click on start button> click device manager> Batteries>then select the s drivers and right-click on it and uninstall all battery drivers.

Then restart the computer and check again.
