The drive is dead. I was able to identify the culprit and it's this chip marked "CHN 031". I am unable to find it.
Can someone tell me what this chip is? Thanks.

The chip appears to have 12 pins: 4+2+4+2

You can bypass this IC by connecting Vin to Vout. Just be sure that there aren't any shorts downstream. Also, make sure that the input voltage is correct.Comment

I didn't get a chance to swap out the chips. The customer took the drive with him and that's that. It would've been interesting to see if the drive could be saved.Comment

Good afternoon everyone,
I bought a joblot composed of 4 Thinkpad L380, 2 are 100% working the other 2 have corrupted bios.
I've dumped their respective BIOSES before attempting anything.On this thread I'll focus on laptop #1(will open another thread for #2).
What I did :
1)ME cleaned the bios + replacing the BIOS_REGION with the latest one, I extracted it from one of the working computers.Now the computer is powering on, but asked a supervisor password.
2) Use the lenovo patcher available on this forum to get rid of the password.It worked.

Hi everyone,
I'm in need of assistance with a Dell Precision 5820 Tower. The BIOS is locked with "Dell Security Manager," preventing access to the HDD-1 hard drive.
**Background:**
I recently purchased this Dell Precision 5820 Tower from a recycler who salvages equipment from abandoned office spaces. The computer was left behind by its previous owner and was password locked. Given that it can run Windows 11, I saw this as an opportunity to upgrade my setup.
**What I've Tried So Far:**

I thought I'd throw out some of my personal experiences in the last 12 months with Intel iMacs, 2.5" SATA SSD drives and Fusion drive data recoveries.
As a backgrounder, Apple never fitted a 2.5" SSD's to these iMacs. Apple's SSD option was a system of 32GB NVMe blade drive (NGFF connector) and Seagate 1TB 2.5" HDD, married together in software to become a Fusion drive. Non Fusion systems have just the 1TB Seagate HDD.
So, the most common reason an iMac comes across my bench is because it's either ridiculously slow, or it fails to boot at all. The most...12-18-2024, 10:34 PM
