    Lenovo is shit. They really aren’t worth a damn anymore.

    I’ve had fingerprint driver issues with my expensive Lenovo Yoga, and AHCI driver issues with an expensive Lenovo ThinkPad. Support is non existent, and if you do manage to find any help through their channels, they don’t help and don’t care.

    My next laptop will be with Framework or some other company that doesn’t try to screw me.








  • That’s not necessarily true, though it is also what I thought as of just a few days ago.

    At least based on the information in this video from MKBHD, excessive heat is actually what causes rapid degradation of smartphone batteries. Super fast charging phones actually work by reducing the overall heat to the battery through engineering designs, such as by splitting the battery into two parts instead of having one entire battery that gets hot. In this way, a phone that supports 50W chargers can charge “each battery” at only 25W, instead of one single battery at 50W. The space between the batteries also insulates the heat between them. It’s simple but ingenious really.

    You do have a tradeoff of less battery power overall, due to the gap between the batteries, but it is definitely a technical achievement.

    I don’t know how EV batteries work, but since the batteries are made up of many different smaller batteries, they could theoretically isolate the heat much more effectively than in a smartphone, which is all crammed into one battery in a tiny little space.
