Hello.
I received a yoga 6th gen ( nm-d341 ) that is not charging, tried both charging and thuderbolt ports but no charge, i don't see any physical damage on them, in fact they look like new.
When i use charged battery works great, i updated to latest bios as i saw a warning from lenovo regarding urgent update to fix charge problems and also updated ME firmware, no luck.
What do you suggest?

Hi guys, I'm repairing a motherboard from an ASUS UX363JA R2.2 that won't turn on, I found a component exploded near the display connector.
I don't have the diagram so I can't figure out what code it has, also if I power the main with the USB-C I have a draw of about 2A at 5V and it doesn't go to 20V.
I checked the mosfets and inductors and everything seems ok, but I don't know what to do.
Do you have any ideas?Today, 03:23 AM -
Hello, i have this OLED here, as the topic says OLED65CX.
TV shows standby led, when pressed the PSU clicks, then shut down.
Disconnecting the 12V VIN from the T-Con, make the TV boot up, led flashes like normal and it stays on.
What i've tried so far:
I have a working TV, an OLED55C1. Similar TV... Took all the boards to the C1, 1 by one, and everything works. So basically, all of these boards from the defective CX (PSU, Main, TCON) works either 1 by 1, or together on the working C1.
However, none of the C1 boards work on the CX,...Yesterday, 06:52 PM -

I'm working on a HP Pavilion Laptop Model 15-eh1508sa that is missing 19v. I've looked at the schematics and want to know what conditions the ISL9238C checks before it enables the gate for MOSFETs PQ8200 and PQ8201,
I havent found any shorts on the board.
I get 19v at +PRWSRC but around 1.7v at the Drain of PQ8201(+vin)

Hi, I am restoring my NV-V8000, and wondering there is 16V 4700uF cap near transformer, is it low esr one or normal one ? On PSU they are all replaced with low esr, but I am not sure about that one near transformer. I tried to google and look at manual but I couldn't find anything.01-16-2025, 03:12 PM

Hello everyone.
Here is the bypass solution for several Lenovo ECs.
This has worked on many ECs.
Only works if password is contained in EC
I succeeded on many models
