I see the voltages on the motherboard battery connector at 3.3V, below 4V they are not stabilized and rise and fall.
Where is the problem?
Thanks

I recently discovered that the dock connector on the Thinkpad X1 tablet Gen 3 uses USB for the keyboard on the POGO pins, I want to use that connector to add a USB 2.0 hub to my tablet case (lenovo medical case for the X1 tablet)
Can't find much info on that bit online, but found lots of info for converting the Keyboards to USB. I wired up a USB port following https://sharktastica.co.uk/resources/im ... ogo-6p.jpg
If i connect a 10K resistor between ground/pin1 and pin5 (NC) i get a USB ding and then i see voltage on the 5V pin, but it drops to 2-3V when i plug in a... -
Hi guys,
i have a damaged keyboard connector on my older Toshiba Satellite M50-A laptop. I know there is LA-A481P motherboard. In attachment pictures there is a real looking connector and i also found a schematic to the connector. But i need help with finding a real electronic part to replace the damaged connector. e.g. on aliexpress (or different page).
It is 34pin connector and the length from pin n.1 to pin n.34 is 26mm. So it means a pitch length is 0.764 mm. I have seen connectors with 0.5mm , 0.7mm , 0.8mm and 1mm pitch length. But not with 0.75. Is it some special custom connector... -

Dear friends, I want to share my experience repairing an ASUS TUF FX506L gaming laptop motherboard: DABKXDMB8E0_F_BKXD. Boardview and schematic are available, as well as the BIOS and ITE ROM.
When the customer brought in this laptop, it was initially dead; it showed no signs of booting for any reason. After hours of measurements, checking each stage, MOSFET, and seeing if there was a short circuit in any capacitor, I discovered a strange 0.7V leakage voltage on the 3V_S5 rail, particularly on the PL9 coil, with the board not powered on. There were 3V_LDO and 5V_LDO voltages, which... -
Vizio e601i-A3 - Has Sound and Display, But No Backlight - Bad Power Supply Board or Bad LED Bulbs ?I was given this TV from my great uncle. He said it just wouldn't turn on one day out of nowhere, replaced the TV, and gave it to me to possibly fix and use for myself.
Upon bringing it home and plugging it up, it showed a standby light.
I powered it on and without a flashlight, the display showed the "V" but the lighting is very dim, but visible.
The screen seems to blackout and stay black, but with a flashlight I can see the display.
With my Playstation 4 connected via HDMI, and running a game I can hear sound.
