Lenovo Onekey Recovery Password Reset for Y550 and possibly other models.

This topic is for advanced users.  There is no default password to my knowledge.

The OneKey Recovery Password is kept at 2 different  locations one is the second partition thats visible for example D:\OneKey App\OneKey Recovery\pw.dll and another in the root folder of the hidden partition.   To remove the password you simply delete both pw.dll files.

How do you gain access to the hidden partition?  Well thats a good question!  One method is to attach the Lenovo hard drive to another computer using a usb adapter and use disk part:

Step 1: hook up drive to a windows box, open diskpart from cmd prompt

Step 2:

DISKPART> list disk

Disk ### Status Size Free Dyn Gpt
——– ————- ——- ——- — —
Disk 0 Online 931 GB 86 GB
Disk 1 Online 223 GB 1024 KB
Disk 2 Online 2794 GB 0 B *
Disk 3 Online 931 GB 0 B
Disk 4 Online 298 GB 0 B

(find the lenovo disk)

Step 3:

DISKPART> select disk 4

Disk 4 is now the selected disk.

Step 4:

DISKPART> list partition

Partition ### Type Size Offset
————- —————- ——- ——-
Partition 1 Primary 252 GB 31 KB
Partition 0 Extended 30 GB 252 GB
Partition 3 Logical 30 GB 252 GB
Partition 2 OEM 14 GB 283 GB

(find that hidden partition)

Step 5:

DISKPART> select partition 2

Partition 2 is now the selected partition.

Step 6:

DISKPART> detail partition

Partition 2
Type : 12
Hidden: Yes <-confirm you are looking at the hidden partition
Active: No
Offset in Bytes: 304229646336

There is no volume associated with this partition.

Step 7:


DiskPart successfully set the partition ID.

Step 8:

windows should have detected the partition now and assigned a drive letter at this point…least it does when I have the laptop hard drive connected via usb. Delete the pw.dll in the root directory.

Step 9:


DiskPart successfully set the partition ID.

Step 10: Put hard drive back in to Lenovo laptop and you are done.
