AN515-51-56G8 Help to indentify an IC please

02-25-2025, 01:23 AM

Hello,

I have an ACER NITRO computer that no longer starts. The power supply is ok, the charging light is present (but flashing - potentially the battery is out of order) but if I try to start it, nothing happens. I injected 1V 2A on the board and saw an IC that appears to be a power supply controller that is heating up.
So I'm trying to find out what it is. The marking is: BAA70N or BAA7ON. Do you have any information on what it is or an equivalence please?

Thank you so much

About 3vs out when injected

by tribalcore20

I have a autoshutdown instantly when pressing power button.

I injected a 2.5V to the 3vs out/3vs and it is eating 2.545A and found out that audio ic and sio is heating up. I remove the audio ic and injected 2.5V to 3vs out/3vs and it is now eating .950A and sio os heating up. Is it normal that those 2 ic are heating up?

Potentially Dangerous Vintage Capacitor?

by Lee Majors

A technician (with his soldering iron) hit the original Oil & Paper capacitor in the power supply of my Technics 1200 mk2 Turntable. It looks like a snubbing circuit capacitor/noise suppression? rated 0.047uF 450V, Orange Panasonic most likely from the 80's.

His response was it is just cosmetic and there is nothing to worry about. However, I'm not filled with confidence as it is in the AC power section....

Can anyone help me out and can confirm its safe? He hasn't tested it, so I'm not sure how he would 100% know. I am nervous it could fail at some stage....
