Perhaps a power supply failure of a critical supply source preventing the cmos bios from running.Remove the PS, connect a jumper from pin 19 (green) to ground (black wired pins, perhaps 20 or 21). This turns on the supply.The fan in the supply should run and stay running.Then, using a listing of interface voltage levels for the power supply....probably ATX standard if a desktop...measure the
I have to replace a very old UPS. We've got a new one. I'm not really a sys admin, but have to act the part, as the previous one left and, well there's no one else. He had it set up with 2 UPS's, and split the power supplies from each server (5 total) so that 1 power supply went to 1 UPS, and the other power supply went to the second UPS. We've got the new UPS in place.
HAF 912 case, AMD 8350, Gigabyte 990fXa-UD3,1000 watt Rosewill pwr. supply, MSI 7850, 32 gig RAM, 1x1.5T WD black and 1x1T WD black RE4, 32 gig, Sandisk SSD for boot accelleration. Hyper 212+ with 2 fans, and a total of 5 case fans, pulling in at the front over the HDs, and pushing out at the top and rear.
I don't OC, I do game for hours and my temps are all great. Here is the problem.
I have a Lenovo Y460p running Ubuntu 12.04 (64-bit). The battery does charge normally, but unplugging the power supply only very briefly shows the correct battery indicator. After about 1 second, it reverts to the charging indicator.
A few day ago, i decide to an upgrade Radeon HD 5450, to my desktop, and yet it worked on running ubuntu 12.04 LTS with 3D. but i look at Radeon HD 5450, which is requirement 400 watts power supply, and my desktop is running 240 power supply, so is it fine with that, or should i got a new power supply?
What is a good way to determine a power supply voltage for a given OpAmp?
If I intend to have a few volt at maximum signal to manage, what real difference does it make to create a power supply with a voltage larger than the OpAmp is designed to work with?
This is my first time building a PC and I have probably done something very foolish. I wasn't sure if this is the place to ask, but here goes.
The first problem is that the power is not staying on. I know that the power supply is adequate and is working perfectly (I did the paperclip check). What it does is pulse power 5 times and then shuts off.
