    I wish I understood your question but the battery is not removable without disassembly. Do you mean the power adapter ? What is "raw power" please ?

    Raw power means direct power supply using power adapter  without  battery supply

    Well first I would make sure the screws on the back are hand tight (are small so don't play Godzilla). The R3 has a microswitch on the back cover to prevent it turning on when open.

    If the lower case is not securely screwed or snapped into place, the system will disconnect power from the battery. The system will still receive power from the AC adapter. But the battery will not charge or discharge if the lower case is not screwed or snapped into place.

    There is a small button below the RAM slot that detects when the lower case is removed. Please note the second button closest to the board edge is the battery Reset button.

    You may have to do a BIOS default. Turn off computer. Then Turn it on and keep tapping F2 to go to BIOS. Ones in BIOS tap F9 ,Enter, F10, Enter. This will restart computer and most often this resolves the issue.

    Sharanji, thank you for your comment about the tactile switch which disconnects the battery whenever the laptop case is open.

    I recently replaced the RAM in my Aspire R3-131T and couldn't get the laptop to run off battery power after opening up the case. It turned out to be that this button wasn't pressed hard enough when my case is screwed together. I added a bit of material to put more pressure on the switch and it's working better now.

    Many thanks!!!

    I have tried those things. I do not see a case button. I bought a new battery and the laptop would run on it  but would not charge it With the old battery and the power adaptor in the voltage across the battery terminals was 0.855 volts.

    It may be of interest that after disconnecting the red/black wires near the wifi module, to reset the bios, and reconnecting after 15mins, I had to tap F2 key and select legacy boot mode to start the operating system.

    @soundhill1 thanks for posting the disconnect wifi module - that helped me fix my machine. I was thinking it was dead but that got it working!

    More details after the fact. The power connector near the wifi module is actually the wires for a 2032 battery under the wifi module. Battery replacement is a bit tricky - you can probably buy one with the wires from Acer (wires are welded to battery - not in a battery holder like most PCs.)
