Good idea, but not the case here. I've worked with PIC and SOIC programmers for many years on much smaller (tighter tolerances) equipment.

A new (used with warranty) motherboard for this aging machine is less than $30. Just ordered one.

Here's my original BIOS dump: https://www.sendspace.com/file/edkjql

Read it twice and confirmed both copies matched. I was also able to open it and modified the GUIDs.

Thanks for the feedback. I've already done that. 

I've erased the chip, confirmed it is blank, flash my original dump, then read it back and the files match. Still no boot.

What the bios you was flashed? Where you get it?

Thank you for taking time to reply!

I created the modded BIOS by following this guide: 

Here's the modded BIOS: https://www.sendspace.com/file/2lau6m

My newly flashed T450 does not boot, and shows no signs of life other than three flashes of the power LED when an AC adapter is attached.

The flashed bios was verified to match. I've removed all power, RAM, and disconnected the CMOS battery, but even after sitting for hours, there is no change.

I reloaded my factory bios, but same symptoms continue.

Can anyone help?
