Keyboard woes for p170sm-a

Hi, my clevo p170sm-a keyboard stopped working so I replaced it. Unfortunately each replacement I had has something different thats wrong. My original keyboard has a nonfunctional space and several number keys. The first replacement had this annoying bug where if you didn't hit the h dead on especially after not touching it for awhile it wouldn't register and if you rapidly tap the key from the side it wouldn't register all the time. The second replacement is the same way except with the l and m keys. I got these replacements off ebay and they're supposedly for the same model but have slightly different arrangements of some stuff like the windows key. Is this bad luck with keyboards or a deeper computer problem?

btw I cleaned the keyboard slots with alcohol.

 

Honestly sounds like your keyboard slot (the wide one) isn't fully cleaned yet or might be loose. If the RGB works fine, then don't bother clean the thin slot, since that's for RGB only. I don't really think, that all replacements and your first keyboard actually are broken, a lot of the times it's just bad contact or dirt that ruin the notebook.

I'd say, take all your keyboards, bath them in alcohol, then make sure you do an insane amound of cleaning on the slot, then get a can of compressed air and blow into the slot, so you can remove all eventual dirt that might be inside the slot hiding somewhere. Also make sure, the slot is properly on the board, who knows maybe the slot itself got loose because of some broken solder.

 

Tried alcohol on the slot again and no joy. The m key still sometimes decides it doesn't want to register if I don't push hard enough or push too rapidly. How do you get out the black wiggly thing that clamps the cable in place without damaging the motherboard?

 

You just push it away from you on the 2 ends. If alcohol didnt work go for blowing with an aircompressor or your mouth and see if u could get rid of hidden dirt in the slot.
