I hope the heating won’t affect the performance over time. I guess I was wrong about the battery, the manual said 4500mAh and I got worried maybe its a different version. I did check the specs before buying it, it said 9000mAh, its probably a mistake in the manual. Will check with the seller on Monday.
I will reinstall the windows the following days, hopefully without any problems.
Thanks a lot for your reply & wish you a good weekend!
