Hello everyone!
I have a surface pro 4 (1724) with corporate management set up (in this case, I understand it's called SEMM). In the operating system installer (Pro version), after connecting to Wi-Fi, it asks me to enter the company system. If I don't sign in, it won't let me continue (similar to enterprise enrollment on chromebooks). This can be avoided if I install the Home version instead of Pro, and then upgrade to the pro version, but this is not very elegant. I would like the machine to be as it should be in factory condition. That's why I would like someone to remove this restriction...
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

by pc boyHi everyone. An HP X2 1012 G2 came the other day. The problem was that the device drained the battery while off. I checked and saw the current is 0.2 before start. I went and checked parts on the MB and saw that the JHL6340 IC that is responsible for controlling Type-C gets hot. Everything worked fine and I checked charging and data of type-C both were OK. I went ahead and replaced the JHL6340. Now it does not get hot, no current before start, charging is OK, but the data of type-c is lost. I mean any type-c device like flash memory or hdmi adapter etc. do not work. I tried another jhl6340 and...Today, 03:34 AM

I downloaded a BIOS file from Lenovo and once I extracted the actual BIOS from the executable, it is 16MB in size, but my IC(Winbond 25Q80DV) is only 8MB in capacity. I have read you can trim the BIOS file with a hex editor but I can't find any instructions on specifically what you will remove.

by unimatrix93Dear forum, I would like to ask some help identifying the backlight circuits resistors to limit the ampere to the backlight leds.
The power supply is a BN44-00852 and I want to decrease the backlight to increase the lifetime of the LEDs.
The TV is pretty much always on, used for CCTV cameras.
I suspecting R9838 -> R9841 resistors but I'm not sure. Thanks in advance!

by GeorgeRI have an Lenovo l340 that has two missing caps on the motherboard. How can I find the value of the caps so I can replace them.
thank you in advance.Today, 01:49 AM -
by kaydeeI recapped the power supply recapping the Power supply with Toasty's sketch (replaced all Shotgun, as well as "Other" caps besides C4+C5+C37). Somehow the PSU turns automatically on when I insert it in the socket. Did anyone else encounter this problem?
I would be really thankful for some advice.
Best,
