Answer to "Acer Aspire One d250 keyboard not working not even in BIOS!"Hi, These are great netbooks but they are prone to the keyboards failing. I have 2 and have replaced the keyboards a couple of times on both. One way to check is to use a USB external keyboard. However don't forget that the USB sockets don't always startup until windows is fully opened. If the netbook can be switched on and windows starts then try plugging in an external USB keyboard. If that works it is your keyboard on the netbook that is at fault. If you are using win 7 it should allow windows to startup without having to access the keyboard so that you can try this. If you are on win 10 it is a bit harder but it still may work because win 10 starts the USB ports earlier. If it is the keyboard a new one is about £10 on ebay. Remove the old keyboard with an old credit card or similar and push the card corner down between the keyboard edge and the plastic at the top of the keyboard. The keyboard is held in with two lugs at the top and one either side that need to be prised out with the old credit card....
Answer to "Touch screen won't work after screen replacment"A possible cause is that the short ribbon connectors that go back into the small L shaped board that had to be transferred from your old screen to the new screen. If these ribbon cables are not pushed in far enough or are slightly off the touch will not work or works strangely. I read this on another forum somewhere and can no longer find it but it seems a possible culprit to me.
