Step 1: Trickle Charge Battery:
- Plug UMPC (with battery) into power supply adaptor
- Allow to charge up to 72 hours (3 days), checking the fuel gauge once a day to check for charge status
- If the battery starts to charge normally, the fuel gauge lights will light up sequentially
- If the battery is able to fully charge, the fuel gauge lights will no longer light up, and when you check the fuel gage level, all 4 lights will light up
- If your battery fails to charge at all after 72 hours, it is no longer usable and you will need to purchase another one
