I have such similar issue with my laptop, all keys of the keyboard are not working, I wonder if the problem relays on the keyboard because I use to get 5 consecutive and contionous beep everytime I power up my laptop and nothing I can do more because the windows OS corrupted ever long ago i.e. can't start/boot at all Mean time I do have a HP AC adapter which its output power is out the permisible range as specified by the dell manufacturer so it can just power on the laptop but unable to charge the battery at all.. Please assist as I do not have any penny to buy anything as a spare or service .. I just need my Laptop to come upa again Thanks for your concern with my Bad English Kitenge, inja1@yahoo.com East Africa, Tanzania
