I bought a laptop two months ago and Im very disappointed with its battery that was draining every 10seconds and after 6minutes its totally drained. I searched a solution in my manufacturer website and i found a solution of updating BIOS AND EC will help the anomalies of battery reading of the model. The thing is the bios version indicating is exclusively for model CB15SH3 and the model of mine is CB15SH35. I UPDATED THAT BIOS IN MY LAPTOP AND NOW IM STUCK WITH THE MANUFACTURER LOGO. CAN SOMEONE HELP ME PLS my manufacturer takes a lot of ticket to respond 😭😭
