i have a fujitsu lifebook T4220 and i have been experiencing problems with the power cord. theres an indicator to show when the computer is getting power from the wall, and randomly this started going off even when the computer was hooked up to a working outlet. basically this means that at random the laptop will just stop getting power from the outlet. so i ordered a new a/c adapter after the other one stopped working at all, and it worked fine for a few hours until it did the same thing. i plugged it back in and its working as i type this now, but obviously it cant be an a/c adapter issue if the new one is starting to have the same problems. i must note that the battery on my laptop only holds juice for about 60 second so i always have the laptop hooked up with a power cord. hence when the laptop decides to stop picking up power from the wall it immediately shuts down into hibernate. any help would be greatly appreciated, i have no idea what to do and i can't afford to lose whats on my hard drive.
