Hello.
I need help in identifying a component. It appears to be 3 pin fuse, marking SEFUSE D5T4YB, but i cannot find any information about it. Taken out of DELL XCMRD 14.8V battery board.
Thanks in advance.

Edit: Got told its D6T, because there was still more gunk on it. Sorry for bother and thanks.

Hello all!

could someone help identifying this ST diode?

Marking EUV C730

Photo attached,

Thanks in advance!...

Hello:

I have both these laptops that appeared to have the same fault so I thought I would have a go at replacing the PCH as something to learn, they both are using the same PCH.


I started on the ACER:

Up on connecting power no signs of life but current is consumed from the bench power supply and the PCH is hot.
All the caps on the top of the PCH are showing 0 ohms and the 3.3v rail is shorted.

I followed the videos from Sorin, Electronics Repair School on Youtube heating from the bottom to install. I practised on around 10 scrap...

Hi there all.

Troubleshooting an SMPS and I’ve found a SMD diode shorted in both directions. The trouble is it has no identification on it. So what do I replace it with and how do I tell where the anode and cathode is and how to mount the replacement?

It is diode D1 on the image.

Regards.

Hi all,
Need help identifying an SOT23-6 with marking JWF9R
Does anyone know what this chip is ?
It can also help if someone can provide the datasheet of this chip.
Thank you....
