How to Disconnect & Reconnect ASUS ROG Ally's Battery?

A common issue with Windows based devices, which work with batteries, is a malfunction with the capacitors of the battery itself. An easy way to discharge the capacitors, effectively resetting them, is to unplug the battery, give it time to discharge and plug it back in.

Here are the complete steps for power cycling the battery of your Asus ROG Ally:

  1. Unscrew the 6 phillips screws located on the back of the device.

  3. Disconnect the battery cable and wait for around 10 minutes.
  4. Press the power button a few times to discharge the battery.
  5. Plug the battery back in, place the back plate on and screw it in.

Also, make sure to not touch or cause any physical damage to the Warranty stickers or “DO NOT DISASSEMBLE” stickers when disconnecting the battery as this will void your warranty making it impossible for the device to be sent to Asus for repairs if there is a hardware issue. If you managed to turn on your console, we strongly recommend making sure that the GPU drivers are up to date!

Let's Recap!

If the Asus ROG ALLY not charging, cycle or disable “Battery Care” mode, use a third-party cable, charge the device using the XG Mobile, disconnect and reconnect the battery, disable “CPU Boost” and update the BIOS.
