Walkom NP-903 Charging Connector Pinout

11-01-2025, 07:22 AM

Hello everyone,
I'm looking for assistance with powering on a laptop that also goes by the names Modern Computer Corp NP-903 or NoteStar NP-903. I don't have the original charger for it, and I'm unfamiliar with the connector type. I'd be very grateful for information regarding the pinout, specifically where to connect the positive and negative leads for a DC 12V 2.5A power supply.

Lenovo TB-X605F fake charging after charging connector replacement.

by thesame

Hy guys, i have this lenovo TB-X605F with charging problem, the tablet is fake charging, i have replaced the charging connector twice, it only draws 0.40 Amps when pluging the cable for the first time then it stops drawing any Amps but the tablet keeps showing the charging image at 0% as long as i keep it connected. I have no voltage at the battery connector with the cable pluged, but i have 5 volts after usb connector on some testing points on the board.

Dell Inspiron 7501 / Vostro 7500 (2020) - eDP connector pinout/panel compatibility question

by pickledegg

Hello. I have an Inspiron 7501 here, it's the same as a Vostro 7500 in some markets (no clue). I was looking to replace the LCD, the panels included with these models are terrible.

I have the schematic and it is a 4 lane eDP port on the board but the pinout seems quite weird, my question is if anyone recognises this weird pinout and knows of any other Dell models that may use it or even any compatible panel models. I have the 40-40pin cable that was used for the models with touch but do not need touch capability, was just looking for a better quality screen and higher refresh to actually...

SAMSUNG UE65HU8500 ONE CONNECT pinout connector request

by AlexVG

Hi,
I came across with
SAMSUNG UE65HU8500
ONE CONNECT BN41-02135
Chassis GOLF_UHD_1MP_JACK

TV can not recognise ONE CONNECT box, so I need to know the pinout of the CN 3301 connector.
Moreover, on the main is written A5V. However, cable connected this pin to the GND.

Maybe somebody have an experience with the same issues?
I need your help.
Thank you....
