    Thinkbook 16 G2 ITL FLV35 LA-K052P.The laptop was sometimes switching on

    Hope i find you well. I have had the following G2 ITL FLV35 LA-K052P REV 1.0.The laptop was sometimes switching on and the after you shut down it would not switch on. I then opened the laptop and tested all the power rails and was getting voltages except on PL48001, PL47001 and PL5001, but when the laptop happens to switch on i would get voltages on the said inductors. Usually when we are faced with such a problem most of us would think of the BIOS, ME Region in particular and using LBE i regrogrammed the ME region and the result was the same, I then did a complete BIos rebuild and this also yielded the same results:
    Solution:
    As a last resort after testing and trying everything i then reflowed the main Processor chip with A BGA machine and this solved the problem and hopefully someone will be helped by this.

    Desoldering gun station modified to use a 18 volt @ 20 amp switching power supply
    by sam_sam_sam
    I have wanting to do this project for quite sometime now and I finally found a switching power supply that will work on this desoldering gun station ZD-915 that the original switching power supply took a shit and just was not worth trying to fix it because this switching power is not quite big enough to handle the heater element and the vacuum pump

    One note when I tested the switching power supply and the voltage control board I noticed that this desoldering gun heat up much faster than the original switching power supply which I was really surprised by to the point that I might buy...

    MSI GF63 THIN 11UCX (MS-16R6) LAPTOP WON'T TURN ON AFTER RESTARTING
    by RdeveLabs
    To all the members here...

    Let me tell you a little bit about what happened to my laptop (MSI GF63 THIN 11UCX model: MS-16R6) that “maybe” you know how to solve this problem.

    So before this problem happened, my laptop was running smoothly. When I wanted to restart my laptop, it looked fine at first. But after I waited for this restart process to take a long time, until finally I panicked (because the restart process did not finish plus the laptop screen only showed a black screen), I immediately pressed and held the power button to force the laptop to turn off. But...
