    Razer Blade 14 (2014) Motherboard Swap, Issues

    Hi Guys,

    I had a keyboard and touchpad failure on my blade 14 2014, got the unit inspected by Razer and got a quote of 1000$ to fix (motherboard needed replacement).

    Instead, I got a used, functional board from ebay for much less and installed the board myself. I repasted the CPU/GPUs when I detatched the heatsink and put the new board in, did a fresh install of Windows 10.

    My only issues now are:

    1) Battery Life and Charging indicator are incorrect (the battery charges correctly, but the remaining life is not showing correctly). The laptop sometimes shows the battery is charging and sometimes not, but it actually seems like its charging correctly. If i leave the laptop plugged in and shut down, if I boot it up later, it shows the laptop is charged to a certain percentage. Anyone know how to calibrate the laptop properly? I did a BIOS cmos reset but doesn't seem to help.

    2) My touchscreen is not working. I figured that the touchscreen and webcam are routed through the same cable to the board, and my webcam is working. I have the following errors in device manager:

    Event viewer shows the following event when Windows tried to configure the device:

    I get a similar error when I boot into Ubuntu.

    Any ideas on what might be going on here?

    I'm getting the same error on mine as well. I don't know if it's a Windows 10 driver issue or just a dead USB port. Hopefully someone has figured this out.

    Hey, I have a similar issue with my keyboard and trackpad, with the same tale of customer support (replace the motherboard for a thousand dollars). Can you tell me the motherboard you got and how you went about replacing it?

    Pardon me, if I come across as a newb.

    Hi,
    as far as i know, error 43 is a Hardware issue, i once had a ball of solder under my gpu and that ball shorted a cap to ground. Caused my RB to disable the GPU with error 43 report.

    Maybe the plug is just not in completely.

    To the charge-controller, its a Texas Instruments BQ25A.
    Don't know how to talk to SPI Dvices jet, but if you figure that out, you could dig very deep.

    Datasheet: http://www.ti.com/lit/ds/symlink/bq24725a.pdf

    Might just be a driver issue ;D

    But i do have a problem with my charge-controller too and i haven't jet figured it out completely.
