ThinkPad Keyboard : Failing electronics !?

2020-10-08, 15:16 PM

LED Status indicator for Function Lock (Esc key) is has lost its intensity.

 

Strangely, when I turn-off other functions with LED Status Indicators (Caps Lock, Num Lock, Mute, Mic On/Off) the intensity of this dim LED increases. The laptop is kept clean and has managed to stay away from any spills/falls, so far. I wipe the keyboard with cloth damped in Iso-Propyl alcohol once a month.

 

1. Is this a sign of failing electronics related to these LED Status indicators, in the future?

2. I suspect a possible effect of power-surge, as I mostly keep the charging adapter connected!

3. Anyone else observed this problem?

 

 

 

 

Additionally, I've got this bug with my CapsLock key some 4-months ago (for which I've mailed Lenovo but no response on it yet!) :/

 

I can turn ON the Caps Lock function, but cannot turn it OFF. I discovered that to turn it off, I've to press Shift key below it instead. Sounds like a corrupt code or buggy update somewhere.

Just to inform you, Caps Lock function on the On-Screen keyboard works fine.

 

My last resort would be clean install windows, but really would like to know, if there are other options.

I have never noticed any such issue with mine. You could perhaps try purchasing a new keyboard from ebay or your local lenovo parts dealer (this website or a brick & mortar store) and trying that one?

Thank you for suggesting. I will bookmark the website for future need. For now, I think LED is not too big of a deal to get the whole keyboard replaced.

 

BTW, Happy Holidays in advance. :)
