Hey, all. I Have clean my fan in my aspire v3-471g. And complete the setup to turn on laptop. When I first boot, the only "A" isn't work at all, even when i in bios setup. I disassembly again to check the keyboard. now the esc, tab, capslock, shift, A and other left-top key doesn't work.
But i dont want to change the keyboard after I see the different between i assemble all the case of laptop and when the laptop is disassemble (only keyboard connected to motherboard).
When its in disassemble, my righ-arrow key, and Q key isn't work. but when i assemble all the case, right-arrow key, and Q key is working again.
