I am running vostro 1510 with very similar issues. If I start up with out the power adaptor connected The keyboard and mouse will not respond to any input. Unfortunately I can't remember after which upgrade this started to happen. The interesting thing is even if I boot from earlier versions it still will not work.
When powering down, by holding the power switch, earlier keyboard input can be seen in the top left corner of the screen just before the power shuts down. I have tried all the recommend quick fixes but none of them work for me (assuming I did them correctly). This is getting to be a very serious issue for me. If I cannot find a fix in the next couple of days, I will have to dump Ubuntu and go with another OS. It is basically making the laptop almost useless. -- Dell Laptop vostro 1310, Internal Keyboard and Touchpad not working anymore on 9.04 jaunty https://bugs.launchpad.net/bugs/334249 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
