Re: Sourcing IP2315 IC
Thank you. The shipping may take a while, and there are some concerns about whether it's a genuine IC. I was hoping one of the forum members might suggest an inexpensive donor contaning this IC that I could find locally. Anything that charges batteries via USB-C, like a flash-light, etc might have it.Comment

Re: Sourcing IP2315 IC
As a general comment, China will clone a popular component that will allow them to scam a larger customer base. Openly, do not see this component as a 'runner' so doubt that the part will be a fake. Rather, it is a less popular Asian brand of a controller IC. Lots of those out there. The tooling and startup costs to build a replica for such a small market does not make sense for them to do. Aliexpress has a few resellers of the part and perhaps consider to buy a few from each. We have had a very good success rate in seeking out replacement parts for service and/or building of new designs.
Select a vendor with a high customer rating to move forward. Just my 2 bit feedback.Comment

Hello everyone,
I am new into this, sorry to post it here. I want to make this as a pet hobby project, as this mac is not urgent.
I have (Macbook Pro 13inch 2017mid) A1706 820-00923-A
My mac had liquid damage a long time ago, the connector from J8500 is damaged on pin 46 (PP5V_S0_ALSCAM_F), I guess the LCD/display panel is in short circuit, as I saw the connector from the LCD burned as well.
And the resistor L4004 is literally burned.
From what I see from the schematics, it does not affect any other rails, only the connection to the display... -
I replaced the broken usbc connector on this Ciontek CS50 mobile device. It worked fine afterwards, although it looks like the battery went down quickly and the device got warm at the back (battery section). After putting it in standby for a while it didn't came back anymore?
The battery is still charging (red led), but no power on.
I had another look at the usbc connector, it looks like one of the components is melted down (blue marking)? I have a picture of an untouched device and then the repaired device with 2 pictures; what are these components with B1 and PB marking? Are these...07-13-2025, 02:37 PM -

Hi guys.
Got a strange issue with a Dell 15 9510.
No liquid damage.
A client put it in the IT room for a year, boxed up. Now they come to use it and it's not working.
I put my USBC tester to it and it switches to 20v but is not drawing any current. 0 amps.
Nothing is shorted.
Any help is appreciated.
Thank you
