Will a Larger UPS Prevent Power Spikes
Posted on 2010-09-09
I have been having problems with my daughter's PC. Every time she turns on the printer or sends a file to print, there is a spike in the power that causes her UPS to make a quick sound. Sometimes her computer locks up. For other reasons, I just purchased a new computer and the problem remains.
Here is her set-up:
1. The UPS is an APC Back-UPS ES 350. It is a few years old and is rated at 200 W / 350 VA.
2. The computer is an Acer AX3400 and the monitor is a 19" LCD. The computer and monitor are plugged into the UPS sockets that provide battery backup.
3. Her speakers (small ones), desk lamp, and pencil sharpener are plugged into the surge protection only plugs.
4. Her printer is a Brother HL-2040 laser. We have plugged it into the UPS in a surge protection only plug, and directly into the wall. Either way when the printer starts to run we get that pop and problem.
Q. Would a new, larger UPS with a much higher rating prevent the issue?
Q. If yes, how high a wattage rating do we need? I do not care about having a run time of more than a few minutes. I would only buy a bigger UPS if it would fix these power spikes.
Q. Could this problem be caused by the printer itself? If I need to buy a new printer I will, but I prefer not to.
Q. Any other suggestions how to fix this?
Thanks (from my daughter and I)!!!
