Question about Computers & Internet

1 Answer

My grand daughter has a Dell Optiplex 620 that stopped working. Pushing the power-on button does nothing, no lights anywhere except for the yellow aux. power light. When I connect the power supply plug from the MoBo to my power supply tester all lights come on, on the tester except for the, -5V light & the CPU fan turns on. Would this indicate a bad power supply?

When powering on the PC and you get no beeps, but you are getting power to the fans and hard drives, this may indicate either a bad power supply or bad memory. You can take the machine into a pc repair shop and have them test the memory and PSU for you.

SOURCE: Dell Inspiron 5160 wont turn on

I would suggest that first try running the psa test on ur system which could b done by press and hold FN key and power button together and leave it as soon as u see anything on the screen or any led in case u get any error code or beep sounds then it has to do with hardware and u ned to contact dell in case ur system is still under warranty.which lights do u see come up when u press the power button.I guess u r talking abt the led's for capslock , numlock and scroll lock.try reseating the memory module from the system and try running ur system on one memory chips and vise-versa because it seems that may b the prob is with the memory sticks.
in case u want manual for removing the memory sticks try using support.dell.com and u would get the manuals from there.

Hi,

Take out the battery and try booting the machine on AC power only. If the machine boots up then let the operating system load up, the shut it down. Remove the AC jack and put the battery back in again, then power it up.

If it boots all is well if it doesn't then there could be a problem with the battery.

If the laptop won't start on AC power, what you could do is remove the system memory, clean the brass pins and the slots and then re-seat them/it.

Then try to turn the machine on.

Good luck.

Why does my desktop DELL Optiplex 1700L just flash YELLOW and refuse to come on, motherboard light is on


An Amber (Yellow) blinking power button indicates a low voltage problem. This can be caused by a defective power supply or a defective motherboard. Just to make sure that nothing else is causing the problem, remove any PCI cards like modem, video card, sound card, etc... Remove the memory modules and disconnect cables to CD/DVD drives. Look at the USB ports to see if any are damaged.

My dell optiplex light is solid yellow


That usually means the switch on the power supply has been moved to 220v vs 110v. The switch is located just above where the power cord plugs in.

Dell optiplex gx520 flashing yellow light on motherboard


According to the information you gave it seems it can still be the RAM. I've had a few PC's unable to startup due to bad memory.

Either that or the the front panel conectors are wrongly connected. Sometimes they do have a color code, but it's best to reference the manual. Can be the button . . .

If this is no help, I'd like to know more.

Hi,

Having worked with Dell computers before I have found that the amber light usually means bad power supply.
Get a replacement power supply from a know working Dell machine as their power supplies are different from standard ATX power supplies.
