Please check whether you are getting any power on the UPS or not. In case it is not working even on the AC power, then it might be the transformer inside the UPS which has burned. It can be easily repaired by taking it to any APC service center. This does not seem to be an issue with the battery since the UPS is not even turning on
Testimonial: "Thanks guys for the advises you had help me how to solve the problem. "
If none of the outlets have power, then it's a problem with the outlet or the hardware of the UPS. If only the battery backup outlets are not working, then it is likely a dead battery. The UPS has a "self test" function that will check the voltage of the battery when you turn it on. If it doesn't pass, the unit will usually beep and let you know that it the battery is weak. Batteries are pretty cheap for this unit, here's a link to one under $20: http://batteryinternational.com/apc-backups-es-be350es-ups-battery-ups-batteries-f1.html

Your external battery probably totally discharge or maybe your machine is not charging the battery anymore because of the broken or bad IRDA (i/o) ports from where you connect the power adaptor to the machine or the worse part is the charging chip inside the machine is already bad that needs to be replaced. The good news is is it can still be repaired. Give us a call if you still needs help at (775) 358-2922 as for Randy or visit our site at http://freshpoint.org
I know this is an old question but for those who are looking for a solution i narrowed it down to the power button board above the keyboard. it seems that if you power the computer on and then quickly remove the board from the ribbon cable the computer will stay on.
Try removing the batteries (at least) overnight and putting them back in later; there are circuits that operate with extremely low currents that may be 'remembering' its condition.
These things can keep time and date for ages so there are things active inside even when not in use.
I know Xmas is coming but you still have a couple of days to let it 'rest' without batteries and that may cure your problem.
Good luck-
Your problem may be due to corrosion on the
battery contacts inside the camera
which can prevent the full power of the batteries from flowing into the
camera. Try this free fix before you do anything else: remove the
batteries and wipe the camera contacts firmly with
a dry cloth (heavy corrosion may require cleaning with a wire brush,
steel wool, or sandpaper). Remove any residue that may have fallen
into the battery compartment during cleaning, then wipe both ends of
the batteries and place them back in the camera. This cleaning clears
the problem about 90% of the time. If it doesn't work for you, the camera may have
a problem that requires professional repair.
If you hear winding noises, it sounds like you may have somehow damaged the gear/motor mech that drives the screen. Try GENTLY wiggling/tugging on the screen as it powers up to see if you can free it. If not, seek a repair shop.
