Hi Guys,
I thought I write you a tutorial on how to remove your bios password from your lenovo x390 yoga.
Steps:
1. Get an EC programmer and read the EC firmware.
2. Back up your working EC file !!! (on this modell EC stores all hardware infos and you cannot replace it with others)
3. In your EC firmware file find all of these ranges with a hex editor and replace them with 00:
!!!!!! IMPORTANT THAT YOU ONLY MODIFIED THE SPECIFIED RANGES AND NO MORE.
(I have used HxD Hex editor FREE for this since I found that it is easy to replace ranges)

Hi, I'm repairing this Chinese SG2701B01-7 panel. There isn't much information about it. The original part for the panel is a CSOT CS601C regulator. I can't find anything commercial on Aliexpress; there's only the CS601 without the final 'C'. They claim it's a variant. But will it be compatible? Well, my diagnosis on this screen is a video problem; the image is practically black, although there is HDMI communication. The LED light is on (backlight), but there is no VGL, no 3.3V, and no VSS. It seems that this IC is the one controlling these voltages. The monitor worked correctly for a moment and...

Dear Forum Members,
There are many non-authorized sellers who sell spare mainboards for laptops. The question is how do they provide these mainboards?
It is possible that some of these mainboards were defective working mainboards that were set to be recycled in the factory, but they were sold as spare mainboards. It is also possible that some of these mainboards were defective working mainboards that were replaced by a new one so that the old one was sold as a spare mainboard.
Defective working means the mainboard still works but it has some minor problems. In the... -

Hi,
I got two HP Mini 800 G5 machines, both 65W mainboards (have all 12 FETs populated on the CPU power rail).
One board is always throwing errors in MemTest86, no matter which known good CPU/RAM combo installed. Board is fried. Period. Will be scrapped.
The defective board contains a Win10Pro license in BIOS.
The other board is working perfectly fine, but only includes a FreeDOS "license".
I want to transfer the Win10Pro license from the fried board to the working one. If that includes transferring S/N etc, I'm fine with that, will...
