by coasterghostFor Badcaps Readers, Please note that I am hopefully going to present this same message to Lenovo to see if they have any insight to the matter as well and figured to share the entirety here for clarification. The System is out of warranty as it is but does have the option to have it extended.

by AWFRONTI have recently purchased a Lenovo ThinkBook Plus Gen4 Twist with Dual Screen. Here are the links for the product information:
ThinkBook Plus Gen 4 (13″ Intel) | 13.3″ & 12″ Dual-Screen 2-in-1 Business Laptop | Lenovo UK
However, somehow the serial number and the product name is no longer showing under the BIOS, Windows 11 or Lenovo Vantage.
Strangely the laptop's under cover does not show any information about the Make, Model, Type or Serial Number (No sign of tampering but no labels etc...). I am not sure what to do.
I do not have access to the original box...06-21-2025, 11:09 AM -

by Forest79Hello,
I got a Lenovo ThinkStation P520 (Type 30BF) from a friend, asking me for a repair. Windows 11 offered a firmware upgrade as an optional update, and it failed.
The emergency flash procedure from the hardware manual has also failed. So, I asked an acquaintance with better skills to flash the BIOS directly.
However, the chip (a Macronix MX25L25673GMI-08G) has a size of 32 MB, and the BIOS file from the Lenovo website (extracted with UEFITool) has a little more than 16 MB. Thus, the software my acquaintance used (SiberiaProg v1.45, with a CH341A Programmer)...-
