Lenovo ThinkPad X240 unlocked BIOS menu / wlan / wi-fi whitelist mod
[email protected] replied to Klem's topic in Lenovo
Hi, do you know how to downgrade Thinkpad X240 the BIOS from 2.49 ? It seems reflash via programmer is the only option, isn't it ? I installed 2.49 (lastest BIOS) and battery significantly reduced. The uncore power was very high (almost 3W), I found noway to reduce this uncore power to normal (< 1W). But when I try to downgrade BIOS via Windows, it does not work. I tried to run command Winflash64 /sd /file but it does not work either - it works on x230, not x240. Sorry for my English, it is not my native language.
