My acer extensa 5620 keyboard is not working properly, some keys do not work at all, I even tried to blow and clean but the problem sustained, then I checked the driver software as I thought it could be the driver problem still some of my acer extensa keys are not functioning properly?
Solution:
The largest cause for failed keyboard or keyboard keys is due to the liquid spilled over it, if this happens unplug the main supply and quickly remove battey from its compartment, now unscrew your acer extensa and wipe the residue of the spilled liquid and allow it to dry under some heavy light, after that assemble the laptop and check if it is now working properly or not.
If you have not accidentally spilled liquid then your keyboard might be failing because it is not seated correctly this might happen if your laptop has experienced a severe jerk. For resolving this issue open the screws and take out the keyboard, reseat it properly and check if it starts working.
You can figure or perhaps solve your acer extensa 5620 keyboard problem by using a keyboard mapping software. Keyboard mapping software helps you to check whether your laptop is getting the signal from the key or not. If it is getting signal then there is some dirt between the key and the keyboard contact you can solve it by simply unscrewing the system and cleaning the dirt, else if it is not getting signal the problem might be of a broken or damaged circuit path of key, in that case you would be needing a professional acer laptop repairing facility help.
