If I could ask for my Lenovo L14 Gen 5

LB4-1 Intel
223139-1

If it would help and thank you in advance ♥...

So late update but I DID IT!

I managed to solder the new USB-C port and it work flawlessly now

I used low-melt solder for the pads and on the anchor pins regular solder to give it more strength, hope that was not a bad thing to do for the long run :/

Thank you all for your help and time, I never thought that I could make it but that was definitely a good start for me to get used to soldering with hot air and I hope, that I'll learn and do more with the time!...

I found the SY6288D20AAC which looks good... I think...

Nothing, no 5V or PD negotiation, I even externaly powered the JC-7 but it's dead. Even when I try to attach as USB-C device, only works on one side (tested just now) so I assume...

A worn out USB-C port (nice... yesterday first time desoldering a tiny IC with hot air and now an USB-C port although I have low-melt solder w/ bismuth)

The J7-C test only powers up on one side, the other side it acts like being not connected.
Are there any testpoint on the board to test the USB-C pins? I have a breakout board for USB-C so I could check for continuity on each pin (the manual way)

I also realized this morning that only the USB-A port on the same side doesn't have 5V, the other side still functions fine :o

Hmm... Both USB-C/TB ports takes power and PD in except the first/upper port only on one side, I tried with several cable different cable and my Lenovo USB-C brick (don't have the Dell original one)

Maybe USB-C port is a bit loose? Loose and somehow bricked the IC by accident? (At least no heater inside anymore)

I use a J7-c in between to check the voltages and something caught my eyes, I have one cable with a small display for Watt reading and if PD is enabled or not, no matter how I flip it, it keeps blinking on the first/upper port but not on the second/bottom port...

I'm honest with you... I have right now no idea what I am looking at, the datasheet says something about 5V power limiter but... I had issues with charging the notebook at 20V (or whatever PD negotiated) and ...

*brain melting* So I need a replacement USB load switch for 5V and 2.5A (that probably is meant to prevent over-current over 5V for all ports

Uhm, now I'm bit confused but on the chip itself, I got these readings;

IN - OUT = 2 Ohm
IN - GND = 14,5 Ohm
OUT - GND = 14,5 Ohm
(used the G524 images as pinout)

On board I got;
IN - OUT = 16 kOhm initial, raising to infinite kOhm slowly
IN - GND = 2 kOhm initial, raising to 4,6 kOhm
OUT - GND = 500 kOhm initial, raising to infinite kOhm slowly...

Ahhh okay, TY

1L = 500 kOhm initial, raising to infinit kOhm but slowly
2L = 1, 1 Ohm
3L = 55,9 kOhm
1R = 2,4 kOhm initial, raising up to 4,3 kOhm
2R = 104 kOhm...

Hey guys,

so my half-year out of warranty Dell Latitiude 5320 (19817-1 SOUTH PEAK 13 10L) w/ i5-1145G7 and 16GB just started to act weirdly...

The first/upper USB-C/TB port suddenly didn't accepted the charger every time and sometimes only a different one... or with a different cable but so far, the self-diagnostics didn't noticed anything so I suspected a dirty port.

Today however... it stopped completely to accept a charger, the second/bottom one however does and after a half an hour, I notice something getting hot under there... blazing hot!

Oh sry, forgot to introduce myself

Came here because I had... something... now a new thing and yeah... you'll see my post soon ^^...
