Greetings folks,
I wonder, if there is a section for troubleshooting also smart watches in this forum. I put it there, because it is closer to mobile devices, I suppose.
Anyway, I got this watch as not working after very long time of not using them ( not sure, how relevant is this information, it could be also any other issue, but that's what I was told ). Indeed, the battery was totally low = 0V, but even after reviving it with the help of PSU, or even if I replace battery with PSU 4.0V, there is no sign of life after pressing the power button. Pressing both buttons should...

Hi guys,
I have a set of Logitech R20 speakers, one of the speakers wasn't working, so I took it apart & there was no continuity or Resistance when probing the Tinsel Wires. Plus looks like the speaker was exposed to liquid as there's rust on the metal speaker frame.
Just in case, I removed the other speaker and installed it in place of the damaged speaker to make sure the PCB of the damaged speaker was ok & it seemed to work fine, so it looks like it's just the speaker for now.
Printed on the back of the Logitech speaker is;

Hi guys, I have this macbook a1278 which doesn't have any image on the display, but when I turn it on I hear the chime.
I found the L9008 choke open and reset it.
When I turn on the macbook I have about 3v on pins 3 and 4 of the display so everything is ok but I still don't have the image.
On the backligt pin 21 and 22 I have 0v but the fuses are all ok.
What can I check?

Hello everyone,
I have an ASUS Vivobook 14 OLED M3401QA which is not posting. Currently when plugged into power/turned on the power indicator will illuminate and the battery indicator will flash white roughly once every 3 seconds. Leading up to this it would sometimes turn on and then other times not turn on, furthermore it also showed a screen saying "new cpu installed, fTPM/PSP NV corrupted or fTPM/PSP NV structure changed" and then a screen telling me to recover the bios however it is no longer even posting at this stage.
The diagnostics steps I have attempted...05-25-2024, 02:34 PM -
Hello,
I have a A1706 with 820-00923-A board. The laptop came in with non-working keyboard. I bought a new top-cover with keyboard and transfered everything to the new topcover.
Since then the macbook will not charge or power-up. Before replacing top cover, I started the macbook to test, and it worked fine apart from keyboard. Then shut it down and did replacement.
This is what I measure so far:
Resistance from F7000 to ground is 123 Ohm on pin 1 and 2
PPBUS_G3H = 0,79v
PPBUS_HS_CPU = 0,79v
PPBUS_HS_OTH5V = 0,79v
