Question about PC Desktops

1 Answer

Does not have light on for power. Tried my work computer and a different power cord. It does not appear to be getting power. It looks like there might be a reset button (slot) on the back side. Any ideas, or is is time for a new one. It's probably five plus years old, and uased at home. Thanks, Hank

At that age it's most likely a faulty power supply inside the case and the problem is, if it's not a good make power supply it may have taken the motherboard with it, this actually a very common problem and what I spend most of my working hours putting right.
You need to weigh up what is the most financialy viable way out, a new machine or repairs. If you decide to go with a new machine and you have any personal files saved on the harddrive of the old one they can be very easily recovered.

Dell inspiron 531s will not power on. It worked just fine and after I moved to a different home, it does not power on at all. I have tried different electrical outlets


Assuming you have tested those outlets with another electrical device (such as a lamp) and they are getting power, the problem might be the power cord, or static inside the computer. Try this:

1. Remove the power cord completely from the computer.
2. Press and hold down the power switch for 10-20 seconds. This drains any residual static in the circuitry.
3. Re-attach the power cord. Make sure it is seated firmly on the end that attaches to the back of the computer.
4. Plug it into a known good outlet and try to power on.

If that does not work, try replacing the power cord with a known good one. If it still doesn't power up, the problem could be either the power on button, or the power supply itself. Either could have been damaged during your move. You could open the computer case and see if anything appear loose, or any wires are obviously detached.

Power supply modules do ocassionally go bad on computers. They are not that expensive to buy, and not that hard to replace, though it might be a challenge for a novice. Before you buy and/or replace the power module, be sure to have the machine tested at a local store (Radio Shack, Best Buy, Office Depot, etc) to make sure that is really the problem. Many stores will perform a power supply test for a nominal fee.

I shut down my Dell Dimension E510 last night and today when I pressed the on button, the computer wont turn on - not even an orange light on the power button. I tried disconnecting all connected...


Try this procedure! click here. After checking your power supply and it is working fine, put it back again into your computer casing. Next thing to do is to check your motherboard switch (power on). Look for the manual of your motherboard and look for the power on switch. If you find it then get a screw driver and short the pin using the screw driver. Be careful not to touch the other pin! But you have to check all the computer components to determine what is exactly the cause why it's not functioning. If it's not turning on your computer while you short the power switch on that means probably your motherboard fail. Other option is, in order to troubleshoot the problem of your computer you must have an extra computer with the same model and plug all your components there one by one to determine what is exactly the problem of your computer. Then you can decide what computer parts need to be replace. Have a nice day!

Have a dell computer when it starts up the moniter and keyborad will not come on .i have checked the cords and are plugged in


Hello there:
I would first try this .
use a different monitor and keyboard (one at a time) and reboot each time and see what happnes just to check things out.
If it still happens than you know it is related to the computer and not the monitor or the keyboard
If not i would unplug the power cord from the computer
open the case and check to see if there is any thing that has came loose.
check all of the cables and cords and the memory sticks.
also remove the power cord that goes to the motherboard for 2 minutes and during this process press in the computer power button for 20 seconds now plug in the cord bac k into the motherboard and plug in the power cord for the computer and reboot
if it works great but if the monitor just works
you can use the mouse go to device manager and uninstall the keyboard by right clicking on the device and selecting remove than confirm the removal of the device and click yes and reboot the machine upon restart the computer will bring up the found new hardware wizzard and it will reinstall the device for you ok now you should be able to use it again but if nothing is working sorry to say you might be looking at a motherboard issue ok
I hope that this has been very helpfull for you
best regards michael

Mi computer doesn't work anymore. It's an HP tx1220. My warranty has expired and a technician has told me that probably it was the mother board. What can I do?


Ok what do you mean by doesn’t work?
No power? no lights? dead?

Have you tried a different power cord?
I ask this because of these things

  • Laptop power cords can just give out without warning

  • And just because the green light on the power cord is lit does not mean it is putting out enough power or any at all

  • And even if you test the power cord and it reads the correct voltage does not mean it is still putting out enough amperage to handle a load (like powering up the computer) Of course that is extremely rare but I have seen that happen before

  • Before giving up hope I would try borrowing another cord from someone with an HP laptop or one of those I-GO laptop cords with the changeable tips or something or even better yet try your power cord on a different laptop and if the other laptop turns on .then well I am sorry

NOTE: if your power cord has a little green light on it and that light goes dim or starts flashing as soon as you plug it into the laptop then that is a very good indication (9 times out of 10) that your motherboard has gone bad and shorted out somewhere.

But there are too many possibilities of what could be wrong with out more info

When you plug it in do any lights on the computer come on at all?

I wouldn’t give up all hope yet .. that is a pretty nice little computer and worth trying to figure it out.

Power supply light on or flashes Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure: CAUTION: This product contains components that are easily damaged by ElectroStatic Discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a PC.
  1. Disconnect everything from the computer, including the power cord.
  2. With the power cord disconnected , press the power button on the front of the computer for five seconds. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps. NOTE: If the power supply fan makes an inconsistent grinding sound or stops and starts erratically, replace the power supply
  3. With the power cord removed, flip the red voltage selector switch to the opposite position. Wait about five seconds, and then switch the red voltage selector switch back to its original location. Ensure that the voltage selector switch is on the correct setting, 115V for North America. Performing this step ensures that the voltage switch is engaged and set correctly for your country/region. Figure 4: Voltage selector switch c00517964.jpg Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
  4. Plug a lamp into the same outlet to see if the wall outlet has power. Try the computer in a different outlet in order to eliminate the outlet as a possible source of the issue. Test both to see if the wall outlets have power.
  5. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet. Test for power. If this fixes the issue, find the device that is causing the issue and do not use it. NOTE: If you find the device that was causing the problem was a surge protector, resetting a breaker or fuse on the surge protector may fix the issue.
  6. Remove all attached devices except for keyboard, mouse, and monitor.
  7. Remove any internal component that was recently added, such as video card, memory, CD, DVD, and hard drives. An added device may take more power than the power supply is rated for. If the problem goes away when the component is removed, the only option is to upgrade the power supply to power supply with a higher wattage rating.
  8. Check the power switch:
    1. With the power cord disconnected, press the power button on the front of the PC. The button should release easily and not stick in the socket.
      • If the button sticks, it should be replaced or serviced.
      • If the power button does not stick and appears to be functioning, continue using these steps.
    2. With the power cord disconnected, remove the case or side panel.
    3. Follow the wires from the power button on the front of the computer to their connection on the motherboard.
    4. Look at the power switch cables connected to the motherboard. If the cable has become disconnected, connect the power switch cable connector to the connector on the motherboard. Figure 5: Power switch connector on Motherboard c00517968.jpg
    5. Replace the side panel, plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
