So about a day ago i was using my laptop, when i was going to pick up my dog and in doing so knocked my coffee all over my keyboard. Some of the keys are either unresponsive or just broken, meaning if I press “W”, it actually presses “F5”. I took the bottom panel off and there was no visible damage to the hardware, but i didn’t go completely inside because i didn’t want to ruin anything. I was going to order an external keyboard to use instead, but i’m not entirely sure if it will work. Can anybody help me? Will an external keyboard work? Is there a way to fix the laptop keyboard itself?
