    Lenovo M700/M900 BIOS mod to Coffee Lake CPUs

    I solved the problem with the disappearing image :cool:. The cause was insufficient cooling of the VR chips on the board. The CPU e-2286m is a "mutant", so it's a few millimeters thicker than a regular i5. The heatsink didn't reach the VR chips, and I had to add more thermal pads. For some...

It might be possible to try flashing the BIOS from an m910, but I haven't tried experimenting with...

    Lenovo M700/M900 BIOS mod to Coffee Lake CPUs

    Check the NVME speed. After CoffeeTime, the speed of NVME drives drops to 700Mb, like SATA.

    Lenovo M700/M900 BIOS mod to Coffee Lake CPUs

    The problem is most likely due to a poorly done BIOS. I had the same issue, but I don’t remember why anymore. My R0 E-2286m (mutant bga1440) works fine in m910x, except for some minor video issues. I did the mod using a script by dsanke and then CoffeeTime0.99 only for "BIOS lock OFF". dsanke...
