A UPS, to a laptop is just like plugging into the AC. It can't compensate for the battery in the laptop being dead. If it won't power on, then you will have to buy a laptop battery.

Thanks for the reply,

i know that its just like plugging into AC, but still the ups usually gives a backup of 10-15min to a single desktop pc,(approx load 220W)

i expect the ups to give at least backup for 5 min.

forgive me for the ignorance, if i am expecting something that i should not and please point me in the right direction, so i can understand the basics.

The laptop obviously needs a functioning internal battery to work. You say you don't have that. No amount of external power will provide what it needs. You will have to purchase a battery for that laptop to be booted.

i mean laptop is working perfectly, but when the electricity goes off, ups is only able to support the laptop for mear 50 to 60 sec....

What is the problem with the ups...

Could be the batteries in the UPS need replacing 'cos they are no longer holding a charge, same with the other UPS you tried.

Thanks for the patience and support from you guys,

I would like to mention,
1. My UPS Battery's are New.
2. Laptop is fully functional without its battery, (Its an old laptop around 10yr old, so i cant get a new battery for it)
3. The problem is probably with the UPS Circuit as its only giving backup of 1 min, that means ups is shutting down while there is still enough juice left inside the battery...

Thanks for the effort.

I don't have an explanation. But an interesting test would be to put a power strip on the UPS and plug a small 40W incandescent bulb AND the laptop. Does the bulb go out at the same time as the laptop? Does the supported time change?
