Re: Required t480 schematic
Hey, I'm trying to figure out if this is the same schematic for the board in my T480. The motherboard is labeled NM-B47 and I know the schematic above is for NM-B501. Not sure if they are similar enough or not.
All I'm trying to do is get the correct part number for the HDMI port because this one is mangled up and needs to be replaced.Comment

Can anybody help?
I have this one for repair, does not charge the battery, does not bring up 20V from the charger. So i input 20v to VSYS from dc power source, now it turns on for a 15 seconds and turns off. Current consumption is 600-700mA. As i can see all power supplies are on expect GFX integrated. Also tried to inject 20V to all the 20V rails at the same time: VSYS, VINT20_IN and USBC_VBUS20 but nothing changes.
Question is, should it turn on with only VSYS supplied?Comment

This is not a Tech section, If you want further help beyond a schematic request start a new thread here:

Give as many details as possible about the voltage, resistance tests you've done so far.

Hi, I am looking for schematic and boardview of Mac mini A2686 820-02579-A. Please help if anyone has it.
For the sake of understanding, this is the problem I am facing:
All voltages are ok on standby mode, but when power is pressed, the voltage drops slowly. And then it does not power on.
It would be great if anyone can help on this.
Thanks in advance.07-25-2026, 05:18 AM -

I had shorted my motherboard while servicing it(adding ssd) to a recently purchased used laptop .
I could find on the motherboard there is one IC gets heats up(photo attached) (can't read the name of IC yet )
If you can help me with the schematic, I would try to solder it myself (DIY/some experienced) .

Hello Friends,
Greetings!
I have taken this active subwoofer from Wharfedale for restoration. This is already in a bad shape as far as the connections goes. It has already been worked by local technicians. The most important part that I am looking forward is the schematic diagram, as there is jumper placed and a track has been cut, as if to bypass the actual connection. I am not sure if this is by design or someone has tried something to achieve.
Another thing is the TDA7294 was badly treated with its legs cut and it had a crack too, so I have replaced it...
