I'm new to I2C programming, and I need to find out / learn how to program R/W RTS5450 and RTS5441.
What hardware and software do I need?
Thank you to the guys at HEGE supporting Badcaps [ HEGE ] [ HEGE DEX Chart ]

How ? I2C Programming of RTS5450 and RTS5441
-
Hi. Good one. Glad it's working for you. Now people don't have to rely on MT3058.
It's been a while for me, so I don't remember how I managed to find the cross reference RT8058....

Needed - Asus Zenbook UX434F Schematic and Boardview
Has anyone got this ?
I can't find it anywhere on the internet.
The closest thing I could find is UX430UN but its fairly different.

Xiaomi Mi 15 Pro - R15-6050A2940901 Schematic
A while ago I got hold of a Schematics but was full of Chinese watermarks with embedded links and crap.
Also Page 6 was mangled with overlapping diagrams of the charging circuit from Page 5.
Same messy version going around the internet on multiple sites.
I've brushed, cleaned and polished this up, and publishing it here.
Perhaps I'm the only one who's done this.
I'm sure you'll all appreciate this cleaned up version....

I found out what Q9102 is. SOT-353 KRX102U or LRX102UT1G....Last edited by gurj1979; 12-17-2023, 02:37 AM.

Hi guys,
I got an Acer Swift 3 SF315-41G with a missing Q9102. I compared it to another board, and the SMD marking shows BM (It's what looks like SOT23-5).
The schematics doesn't have a part number so I can't locate it online.
Can anyone let me know what the part number is or an equivalent I can use ?
Also, the 2nd board is missing the DGPU Enable signal, so the DGPU doesn't get any power at all. This pin is triggered by the CPU. But an I missing another check somewhere ?
Thanks in advance.

Epson L5190 - dead. Help Identify burnt DM301
Hi folks.
I got a bit lost with the new look of BadCaps website. Couldn't spot the Login button HAHAHAHA.
So I got hold of an Epson L5190 with a dead board. Got new MOSFETs and Power IC but still no power.
Power supply is good and gives 2 x 48v. But when connected to the board, it gives 4.4v.
I noticed a 3-pin SMD SOT-323-3 burnt out, but I can't figure out it's marking. All I can see is 5D.
Location of this component is backside of the board (MOSFET side), labelled DM301 (to the right of the black connector).
Can anyone tell me what this part...Last edited by gurj1979; 11-25-2023, 01:54 AM.

Xiaomi Mi 15 Pro - R15-6050A2940901 - no 19v
Hi folks.
Ive got this machine, had broken USBC socket, which popped U2600. I replaced both. Got 5v on USBC, but PVBAT is only showing 2.4v, and also missing 5v on L60250 and L60200, 3v and pretty much every other rail.
KBC is getting 3.3v from somewhere.
I can't for the life of me figure out what is pulling down PVBAT to 2.4v, and not making USBC 19v. Stuck on 5v.
Help please.

Re: Lenovo U31-70 AIVS3/AIVE3 LA-C311P Boardview
Allegro is asking for a password for this boardview. Anyone know what it is ?

Re: Help sourcing an IC number is MT3058
Thanks. It the footprint pins is different than what's on the PCB....

Re: Help sourcing an IC number is MT3058
Looking at the footprint, voltage, amps, MHz etc, the next best thing I found is this. But I doubt the pin functionality is a match. Make or break LOL.
