T440 Corrupt Bios on board fix / direct epprom bios flash

#1 Post by superlativeB » Thu Dec 12, 2019 12:39 pm

Hola. So I picked up a nice condition unit here but its doing the 4 or 5 beeps , pause , beeps no start condition. Black screen , no bios . Have tried USB recovery , burning recovery media etc. I've looked alittle bit further and have seen on board bios recovery / flashing via a cheap USB kit that I picked up but figured I'd check here real quick before I go looking on the web for software to attempt to flash or recover this lappy. Any help at all is awesome , no big deal and very sorry if I posted improperly . Much Obliged, I'm b.p nice to meet yas.

It may possibly be easier to replace the motherboard.
Since T440 has soldered CPU, here's your chance to "upgrade" from e.g. an i5 to an i7
Download the T440 parts list: https://download.lenovo.com/parts/Think ... 131008.pdf
And get the T440 illustrated manual from the above HMM link.
