When a power supply goes bad they are generally not worth repairing given the low replacement costs these days.
I have bought a lot of replacement Dell power supplies from this place over the years.

Remember a lot of Dell power supplies and motherboards are proprietary so you cannot use generic parts.

I have a Tripp Lite G1010USB uninterruptible power supply that only powers the surge surge-suppressor outlets and not the battery-backup outlets. Unless the UPS is unplugged from the wall, and then i


You know they have a TWO YEAR Warranty ?

Sounds to me that it is faulty (one of the relays or switches is not providing 'through' power to the supposed 'backup' socket when the AC power is on.).

Have you followed the manual ?
available here http://www.tripplite.com/support/model/mid/G1010USB

Have you done a 'self test' ?
'To Run a Self-Test: With your UPS plugged in and turned on, press and hold the MUTE/TEST button for two seconds. Continue holding the button until the alarm beeps several times and the UPS performs a self-test. See "Results of a Self-Test" below.
Note: You can leave connected equipment on during a self-test.' see manual

If the LCD does not give you the answer then it is faulty. Seems like something went faulty on restarting your UPS in the morning.

Seems like plenty of help available from this companys' website.

assume power supply is failing or overheating, suggest replace power supply for new one or one with higher power rating to cope with power demand.

My computer restarts by itself in a never ending loop


I have had this happen to my computer multiple times. Once it was because the system was overheating due to the CPU fan and case fan being dead, and the second time it was due to a short in the power supply. I would check either of those two things.

Power supply has several voltages. Just because the 5v power is active doesn't mean all the voltages are OK. You need to have the power supply tested for 12v and 3.3v. A quick test is to unplug all the wires from the power supply. There is a single green wire on the motherboard main plug. Connect (use a bent paper clip) that green switch wire and any black wire. Plug in the power supply and it should run (fan starts)

Hello there martinsjak.

Here's your GEEK-steer ...

First, I'll presume you have of course "lamp-tested" the wall power outlet, as well as the power strip outlet you using, and that also the power cord is in good repair.

With that out of the way, kudos are in order, because your suspicion of the Power Supply Unit (PSU) is very well founded. It is THE most common PC component to fail. Although it could also be the case power button/switch itself, it's likeliest to be the PSU. But regardless of which, the easiest way to find out is to test the PSU.

You have three options:
  1. Manually test it using a multimeter ... Yuk! Only a guy with a plastic pocket-protector (and thinks it's impressive) would pick this one.
  2. Install the suspect PSU into a KNOWN GOOD working PC. If the PC powers up, you know the PSU works. If not ... well you get the picture.
  3. Test it using a PSU Tester. This is a surprisingly desirable option. Why? Because PSU testers are not very expensive, and if you're like most everyone else in this modern era, you'll be in need of testing more than just this one over the course of time. Check out this very solid choice for a Coolmax PS-224 ATX Power Supply Tester.
Which of the above three is your call. Easy-peasy, yeah?

Good luck to you, and thanks for posting back ...

I have a Magnavox 51" Projector TV. Model 51MP392H/17


Hello bullmuscle,

This is a power supply problem, I would suspect the HV power supply because the primary and secondary supplies anymore are tied to the HV power supply. This type of repair requires certain pieces of equipment, to test voltages, look at signals, and to if need be test for shorts in inductors (Switching PS transformer and Flyback transformer). I would not recommend that you try to fix this yourself, The cost for this type of problem is not that expensive and can be done in one evening, if the parts are available. You may be fortunate and it could be just a blown fuse, in the HV or LV power supply circuit

I hope this helps,

Thank you,

Shuttle83
