Recently I had problems with a laptop (tried to solve them in a previous thread). I managed to remove HDD and replace it with another one from another old laptop.
While trying to put in the last screw of the back of the laptop, I noticed that the newly mounted HDD was probably a millimeter or 2 higher than the original one.
I thought that while it may be impractical to have a little bump at the back, but I needed to check out whether the replacement helped or not. When tried to switch on the laptop, it showed no sign of power. I thought that it took me few minutes to replace, so maybe the battery is low and I just plugged it in and powered it on. It started booting, but when I tried to type in credentials I found out that the keyboard is not working at all.
Later I found out that while during startup caps lock flashes once, but then seems dead - I think this implies, that the keyboard is plugged in correctly and is alright. Also after few tries, I can proclaim that the laptop won't start booting or anything unless plugged in outlet.
Can anybody help?
As commenters suggested checking out the ribbon cable, I append photo of it’s current state - I don’t see anything wrong right there, but feel free to correct me
