I recently got a new CWK battery from amazon ( https/www.amazon.com/dp/B00RJU7VC4/ref=wl_it_dp_o_pC_nS_ttl?_encoding=UTF8&colid=2HCPG3H9KRSGL&coliid=I3OQ8050HATFQD ) and the battery works fine but the system wont power on when on battery and the only way to power it on is with the AC adapter plugged into the notebook, however it can be removed once the notebook has powered up. The battery will often times report that it has 0% (even though it has plenty of charge in it) and will sometimes either charge up normally from zero and jump to 100% after 10 minutes or will stay at zero and then jump to 100% after 10 minutes. I dont know why its doing this and would like to know. Please help.
