Anyone know what this component is from a Lenovo laptop? It was glowing hot. Possibly related to the charging chip because that was the only other component that had some heat on the board.

Re: Component ID
Sylergy SY8208B, 3V regulator. Unrelated to charger circuit. Will get hot if there is a short to ground on one of the outputs, or if it's dead.OpenBoardView — https://github.com/OpenBoardView/OpenBoardView

Hi,
I have an Anker SoundCore 2 (A3105) that I saved from the trash (well, I guess there's a reason why it was supposed to go into the trash...). The problem is that it always turns off after a few seconds (sometimes it stays on a bit longer, between 30 and 60 seconds, but it still turns off). The power light turns on and the bluetooth light starts blinking, but both abruptly turn off again. The "turn off sound" is still played after the lights turn off. Sometimes, it also loops the on-off cycle several times without me pressing any buttons. If I connect an AUX cable, music...08-11-2025, 02:14 PM -
Hello!
I bought a P15 Gen 1 as defective and without much hints to its history.
Was sold as "cannot start, weird stuff on screen".
So i bought a replacement GPU (2070 Super) and BOOM it worked immediatly, i got lucky.
Only that error 2203 every single time with beep loud enough to wake the kids is annoying.
I sincerly tried to read up and got a U One to work (3.5.40, that update tool will always say 3-5-40 is latest on cloud althiugh i ran it 3 times, it updated once from 3.5.30 to .40. Is that a problem? P15 Gen 1 is old anyways...)... -
hey Im very new to repairing electronics with capacitors as well as using a multimeter so I need so help/guidance fixing this issue
recently I was handed a family members old NAD C320BEE that they had in their loft for storage for a few years but when powered on it went into power safety mode due to a problem on the protection circuit somewhere before it went into storage I was told it worked fine I found lots of people online talking about how the capasitors are known to be pretty bad in this model and can cause this issue the only problem being I don't have much experience sorting... -
Hi friends.
I have an OMEN 17w board. no shorts in the board. but it cannot provide the 3.3v output from sy8208B IC. although the 5.0v is provided.
instead it only outputs 0.635v not 3.3v.
I have replaced the ic with a fully working sy8208B but still the same issue. I checked the diode values on the all pins of the SY8208B and compare it with the ones on the working board and it matched. So I really do not know what to check next. by the way, sy8208B warms up to 38C when I powers up the board. but no shorts or low resistant component are detected....

Just starting out in electronics repair and teaching myself as I go.
I have here a Corsair RM650 ATX PSU, which I'm treating as a learning project that if successful may be used in my PC.
Fuse was blown, probable power surge from lightning, followed the circuit and found, a dead relay and all the diodes and resistors around the bridge rectifier shorted. Rectifier and MOSFETs seem fine on the LCR.
Also found these tiny diodes on the other side, a few shorted, the rest seem fine. But they're not all marked as Zener on the pcb. So I'm unsure what these should be replaced with....
