Ok, I have read through these forums, and others, and have been unable to resolve this issue after trying like a million things. Here's my issue:
This is on a Dell Inspiron N4030 running Windows 8 Pro with Bios Revision A07.
On boot-up I get this message:
"The AC power adapter wattage and type cannot be determined.
The battery may not charge.
The system will adjust the performance to match the power available.
Please connect a Dell 65W AC adapter or greater for the best system performance.
Strike the F3 key (before F1 or F2 key) if you do not want to see this power warning message again.
Strike the F1 key to continue, F2 to run the setup utility."
If I strike F2 and go into the bios it says "AC adapter type unknown"
If I strike F1 to continue boot-up it boots into windows and then the battery indicator shows "Plugged in, Not charging"
In attempting to fix this issue I have:
1. Replaced the battery.
2. Replaced the motherboard
3. Replaced the Power Board
4. Swapped out the adapter with several other Dell adapters we have in the house (we have 6 Dell laptops). Adapter revisions used are A00, A01, and A02.
5. Did the whole rigamarole here: Plugged in, not charging Windows 7 solution : Jeffrey Palermo (.com)
6. Tried various combinations of plugging/unplugging at different intervals and at different speeds that I have read on multiple sites.
7. Reset the Bios by disconnecting the battery and AC adapter and the holding down the power button for 20 seconds.
Someone please, please help me.
Thank you everyone,
Alex
