My UPS battery had already stopped wokring properly, On monday morning when I had electricity outage(quite common in Karachi) i hurried to shutdown my pc.. while it was shutting down windows, the battery gone dead! After 3 hours when i finally got the electricity back, turned on my PC and while windows was loading I saw some heavy spark in power extension and current supply stopped!
After replacing wires i finally managed to turn my PC on, but it didn’t let me load the windows, instead it started to reboot after showing windows XP logo. I tried everything, booted from XP CD, repaired it, but nothing worked! I then Bought External SATA-to-USB Kit and attached the hard Drive to my laptop and noticed that im no more able to access C:
Attached backup drive and it wasn’t working either, at first it showed up as empty but after trying several times i finally could access a month old backup!. Came back to my desktop, Booted with Acronis True Image Bootable CD and I was able to see all files in C: …. Took a deep breath and felt a bit relaxed! Then I created Acronis True Image Backup file from my old Backup HDD for all windows and system files in C:, transferred it to Flash Drive, Restored to my Desktop HDD, Rebooted, and it worked after running some strange scanning processes and fixing some Disk I/O errors for half an hour.

After all this I at least slept well at around 2:00 AM, Next day early in the morning I got a new battery, attached it and UPS stopped working.. I just can’t explain how i felt! after contacting Systek they sent a repair guy today in the morning who repaired the UPS and its finally working perfectly!! Everything is UP now!
zahid, can you tell the specs of UPS and cost (without battery and battery box).
thanks
