Thank you for all the useful information in this long thread. Successfully revived a relative's 330S-15ARR. Only fan and Power Button light came on. CAPS LOCK did not respond to key presses prior to fix. Novo button did not solve problem. Screen remained blank.

I used the bin file from Post #27 and instructions from post #29 to transfer DMI data.

I purchased a CH341 programmer with all the accessories including 1.8v adapter from Aliexpress for less than 6 UK Pounds. Delivered to UK in 6 days. The seller was Realpoy Module Wholesale, who had sold 5000+ fwiw.

Applications used:
NeoProgrammer v2.2.0.10 (from link in a onetransistor eu article I was reading)
HxD editor
CH341PAR.exe Driver from wch-ic.com

I'm 90% certain the laptop was already running latest firmware ...38WW, updated through Windows Update (It shipped with ...30WW) many years ago. Lenovo Vantage is not installed. I didn't know how to block firmware updates using Device Manager until recently.

Checking the windows update log, there was one update "Lenovo System - 1.2.0.11' installed very shortly before the laptop failed. There is a Pending 2025-08 Cumulative update.


Googled:
Lenovo System - 1.2.0.11 refers to a specific version of the Lenovo System Interface Foundation device driver. It's a system software component that provides a connection for Lenovo Vantage, a system management application, and other Lenovo software to access hardware information and manage system settings. This driver facilitates updates to drivers, BIOS, and other software for Lenovo ThinkPad and ThinkCentre systems
