Please check if the Ac adapter is detected in the BIOS. Tap F2 at startup to open the BIOS screen. Expand General and highlight Battery Information and check what is listed for Ac adapter in the right pane.
It seems to recognize the adapter and the W is correct.
I've tried updating BIOS with the link you gave me. It does not work. I've tried downloading it several times to make sure. The error message I get is this: "Veryfying system configuration.
Error! The BIOs updatecould not be performed because valid ROM image file could not be found. The system will reset. Press 'Y' to continue."
The motherboard was replaced by a DELL operative around 5 months ago, I assume with an identical one as the original. Any suggestion as to how I might proceed?
I have now managed to flash the bios using the update A09 instead of A10. Nothing has changed.
I might also add that it doesn't matter if I take out the battery from the laptop. If the AC adapter is plugged in, performance is hampered.
I've also monitored the cpu under some preassure. While running Dota 2, cpu is sitting on around 2000MHz constantly. This is both with the adapter plugged in, and unplugged. Still, as soon as the adapter is plugged in, fps drops to 2-3. If I unplug it, it bounces up to a steady 70fps immediately. :(
I've also observed some strange things going on with my GPU. With the adapter plugged in. Clock frequency seems normal BUT the GPU load is a mere 3%. When the adapter is pulled OUT. The GPU is clocked down! And the GPU load increase to around 30%. The Voltage is lowered as is the frequency (and temp ofc but only slightly).
I've tried to emulate this behaviour by forcibly clocking down the GPU through NVIDIA control panel, no matter if the adapter is in or not. It works. Somewhat. Like this I can work, and run games. FPS is lower than normal, sitting on around 20fps, but as a temporary solution is ok. It doesn't allow me to change the voltage, but that seems very complicated to do anyhow.
I still don't understand what is causing these problems. Could the computer be detecting a weaker GPU when the adapter is unplugged and thereby compensating somehow making things run better? Which doesn't answer why it's not working as soon as the adapter is plugged in. :(1
I was on leave; hence delay in responding. Thank you for the detailed information. Please check with a known good Ac adapter. In case the issue persists I suspect it is a mother board issue. Please click on the link below to check the warranty of the system. In case the system is under warranty, send me a private message with the system service tag to assist you further. Please click on my name and click Start Conversation to send me a private message.
In case the system is out of warranty; let me know the region you belong to, to provide the contact information to the out of warranty department which is a paid support.

Hi Tina_S,
Please check if the Ac adapter is detected in the BIOS. Tap F2 at startup to open the BIOS screen. Expand General and highlight Battery Information and check what is listed for Ac adapter in the right pane.
Also update BIOS from the link give below:

Reply with the status for further assistance. Also let me know the Operating system

Hi, thanks for your reply.
This is what it says in bios:
Idle
Battery Health: Low
AC Adapter: 240W
It seems to recognize the adapter and the W is correct.
