Your question is slightly confusing. Do you mean that the computer is not powered by a UPS? If the computer is not connected to the UPS, then why have a UPS? If the computer is not connected to the UPS and restarts when you turn the UPS On, your circuit feeding the UPS is overloaded and the voltage dips. If the computer is connected to the UPS, and restarts when there is a power outage, the fault may lie in the reaction of the HP 800. This unit looks to be a line interactive unit and it is not a true on-line UPS. The line interactive and battery backup (no voltage regulation) units both should have a switch to battery power time of 4 msecs, or less. If this unit is faulty and the switchover time is longer, it will not continue to hold up the computer internal power supply. If you are trying to run a laser printer on the HP unit, it won't have enough output capacity.

What problems do these technologies solve in UPS?


1. Provide conditioned clean AC power to computers & other peripherals (except laser printers, which should not be powered by UPS).
2. Protect equipment from the harmful effects of brownouts & sags.
3. Supply power to equipment during a power outage for a specific time, either to allow for the graceful shut down of systems, or to keep the systems working during the power outage (depending on the battery capacity).

The battery will have to be changed if you want to keep the old one.

What i've seen mostly here in south africa. When the battery life has ended they customer opens the ups and takes out the battery and then connects a car battery to the terminals. The then close the ups and let the car battery stand outside the ups.

Hope this info helps...

My universal battery do not have enough back up.


Cpcute,
Yes, initial charge should be for 24 hours before initial use (in general).
The UPS is an Uninterrupted Power Supply and is intended to Power your system in the case of a Main Power Failure long enough for you to Save/Backup your work and shut down your system safely so you don't lose data. Five minutes should be plenty of time to do this? It's not intended for you to continue using your system throughout the Power Outage. The UPS will/should let you know when the Battery needs to be replace, so when it does let you know, replace it at your earliest convenience and it should continue to function as it should.
Good luck.

Battery Backup/Surge Protector Question


Considering the low draw of power you intend for the UPS it will work well. I have two monitors on a strip plugged into UPS along with desktop, routers and modems, UPS handles all well, it's just shortens battery backup times. Have had to power down from outages several times without any probs.

ONLY 2 MINUTES MAX OF BATTERY BACK-UP TIME BEFORE EVERYTHING SHUT


you can program your power bottom to hibernate, and connect the screen direct without the UPS, so you get more time...then when the electricity goes off, without seeing the screen just push the power bottom to hibernate.

Ups troubles


What is happening here is you are transferring load to battery during a power outage but on return of Line Power the UPS is not smoothly transferring back to Normal mode. As a result you are basically turning off your computer. Two options... shut down your computer orderly during an outage or buy a new UPS.
