computer wont power up

15 years ago

Dell Demention 4400 wont power up. No lights, no fans, no nothing.

I have an optiplex 270 that's operational with similar power supply.

Question: Any danger in moving good psu to inoperable comp. temporarly to eliminate psu?

If you're sure same voltages, do it ! Unless the good one is really tiny compaired to the other.

I know I hate to ask but it is the first question any tech support asks and this just happened to someone I know on another forum, he purchased and installed a new power supply o n his pc only to realize that the power cord had some how come partly unplugged from the electrical source, so are you sure it is well plugged in and if you have a power bar or such, eliminate it and try plugging it directly into the wall socket to make sure there is not an issue there.

if power sources specs match up should not be a problem.

Do Ctrl-Alt-Del to bring up your Task Manager, click on the Processes tab, and click once or twice on the CPU tab at the top of the listings: this will show what process is chewing up the most resources (which will probably be the culprit). Also, look at the CPU Usage line at the bottom of Task Manager and see what the % Usage is. Then report back here on what you found out.

It would not be a power overload but a power failure. Power supplies (P/W) have at least 3 different voltages. 12 volts for the fans and hard drives. then 3.3 or thereabouts depending on the computer age and somewhere around 2 or less for the memory. Are you comfortable entering the BIOS? If so start the computer and as soon as you hear the beep tap the F11 button. Once the BIOS is opened use your arrow keys to navigate to the screen providing the power info (scroll left to each screen and you will see where to stop hopefully). Then check the voltages listed, there might be 2 sets listed, the correct one and the actual one for your machine. These are allowed to vary by 10%. You will see the instructions to exit without saving any changes so just follow along (not sure with HP myself)

"F2 for setup and F12 for boot options." Are you saying you get this far and the computer REBOOTS by itself, if that is the case you start to consider a power issue here. How many files did the user want to save? Where are the 2 recovery disks that should have came with the pc, or does it have a recovery partition that you would have an option for after hitting F12 if you get that far. If you slave the drive run your options scan disk, check disk ect, the go to the manfactures site of the hard drive an run there tests on the drive. I wonder if you can get recovery disks from Dell for the 2400 series?

What is the computer model number? Consider seriously before taking it to a repair shop because today you'll likely buy a new computer for close to what you might well pay in repair charges. With the recovery CDs you can do this yourself. It is a simple task requiring very little user input other than agreeing to allow it to wipe the drive so you lose all your data - which the repair guy will do anyway so you may as well curse at yourself as curse at him/her. In fact it might just be a good idea to insert disk 1 of the Recovery set just to see if there is more action than you have now. You can always click Cancel or hit the power button to end the processs. Gene's idea of using a second monitor is great, that will eliminate one thing from the equation. With no beep it does sound as though the motherboard has quit. They made some eMachines a few years ago with defective power supplies which quit without warning. In many cases the power supply also took out the motherboard and replacements were not available. Those computer were instant garbage but I thought that was fixed before your machine was made. Take the left side off your computer and read odd the make and wattage of your power supply

Thanks Mikie and Ravencajun, Power cable connections are good. Swapped out power supplies, it worked. Looked around in me junk and found a suitable psu. It also worked. Been powered up for 2 hrs now and all seems well. Thanks again. These Dell computers require a rather long cable harness because of the way the case hinges, like a book.

gringo50,
Glad you got the power supply fixed.
I have a Dell Dimension 4400 laying here on the floor split wide open like a book.
Craziest case I've ever seen, motherboard on one half and the HD and other drives on the other half.
Took me longer to figure out how to open the thing than to replace the sound card.
The box weights a ton, over 30 pounds.
