1. I would first try to find out if everything is properly plugged in place inside your pc. make sure everything is properly seated

note: BEFORE you get your pretty hands inside the case make sure you ground yourself by touching the power supply before teaching any other components, failure to do this you're risking to damage other componets like memory, or the motherboard.

2. if you did 1 but still the system would not power up, you're problem is likely to be your power supply dying on you. I would suggest to replace your power supply and test.


also check this documentation on troubleshooting power supply issues:

hope it helps.. and post back with your findings.

Vaio desktop blinking power supply


Remove the side pane to access your motherboard cables, etc. Locate the connector on your motherboard that contains the wires going from your power supply to your motherboard. It will be a large, rectangular connector with a lot of individual wires It is not a ribbon cable but should be located next to a ribbon cable connector and next to a green blinking light on your motherboard (when the power supply is plugged into the wall). Note: This green blinking light is in addition to the green blinking light on the back of the PC.

This next step is important: You have to disconnect the connector noted above from the motherboard WHILE the power suply is plugged into the wall. Wait a few seconds and plug it back in. The blinking reen light on the motherboard should now be a solid green light. The PC should now power up.

If the steps above don't work you will need to get a new power supply.

I got a Compaq Presario SR1903wm .with red blinking light !!! power's up for about 20 seconds then shuts off !! doesnt even start up in Bios !! Dont know what to do !! should i replace the power supply...


check the ram memory ..if this shows up OK (verify it in another computer with the same specifications ) ...than the CPU is to blame ..open it up ..and remove for a few seconds the Bios battery to see if you messed up with the temperature settings ..This will reset to factory settings ..and if there is teh case with temperature limits too low set ..than it will power up after ..if it is the CPU you will have to change it

My d530 minitower powers off unexpectedly and red lights starts to blink on System's LED//


Hi Kindly let me know how many times the red light blinks
Condition Code Service Actions Processor thermal protection activated. Power LED blinks red twice, once a second, followed by a two second pause.
  1. Make sure the computer air vents are not blocked and that the cooling fan is running.
  2. Open the hood, press the power button, and see if the processor fan spins. If the fan is not spinning, make sure the fan cable is plugged into the cable header on the system board, and that the fan is properly installed and seated.
  3. If the fan is plugged in and seated properly, but is still not spinning, replace the processor fan.
  4. Reseat the processor heatsink and make sure the fan assembly is attached to the heatsink properly.
Processor is not installed. Power LED blinks red three times, once a second, followed by a two second pause.
NOTE: This condition indicates a missing or improperly installed processor, not a defective one.

Make sure there is a processor in the system. Reseat the processor and verify that it is installed properly. Power failure (power supply is overloaded) Power LED blinks red four times, once a second, followed by a two second pause.
  1. Check the voltage selector, located on the rear of the power supply, is set to the correct voltage (the correct setting depends on the region).
  2. Open the hood and make sure the 4-wire power supply cable is fully connected to the power connector on the system board.
  3. Check if a device is causing the problem by removing all attached devices (such as disk drives and expansion cards), then power on the system. If the system enters POST, power off and replace one device at a time, repeating the procedure until the system power failure reoccurs. Replace the device that caused the failure, then replace each of the other devices and confirm that they are functioning properly.
  4. If you cannot isolate the failure to a specific device in the previous step, replace the power supply. **
  5. Replace the system board.*
Pre-video memory error. Power LED blinks red five times, once a second, followed by a two second pause, and five simultaneous beeps are sounded
  1. Reseat the DIMMs in the memory slots on the system board, then power on the system.
  2. Replace the DIMMs one at a time to isolate the faulty module.
  3. Replace 3rd-party memory with HP memory.
  4. Replace the system board.*
Pre-video graphics error. Power LED blinks red six times, once every second, followed by a two second pause, and six simultaneous beeps are sounded. For systems with a graphic card:

  1. Reseat the graphics card and then power on the system.
  2. Replace the graphics card.
  3. Replace the system board.*


For systems with integrated (on-board) graphics, replace the system board. PCA (system board) failure. ROM detected failure prior to video. Power LED blinks red seven times, once a second, followed by a two second pause, and seven simultaneous beeps are sounded. Replace the system board. Invalid ROM based on bad checksum Power LED blinks red eight times, once a second, followed by a two second pause, and eight simultaneous beeps are sounded.
  1. Reflash the ROM using a ROMPaq diskette.
  2. Replace the system board.*
System does not power on. No beeps or blinks since the system is not functioning. Press and hold the power button for less than four seconds. Perform the following steps depending on whether the hard drive LED turns green.

If the hard drive LED turns green, then:

  1. Make sure the voltage selector (which is located on the back of the power supply) is set to the correct voltage for your region.
  2. Remove the expansion cards one at a time until the 3.3V auxiliary light on the system board turns on. If removing a card turns the light on, replace the card and then see if the system works.
  3. Replace the system board.*


If the hard drive LED does not turn green, then:

  1. Make sure the computer is plugged into a functioning AC power outlet.
  2. Open the hood and make sure the power button is securely fastened in the power harness and that the harness is connected properly to the power connector on the system board. In other words, make sure that the power button is making contact with the power circuit.
  3. Make sure the power supply cables are connected properly to the power connectors on the system board.
  4. Check to see if the 3.3V auxiliary light on the system board is not turned on, replace the power supply. **
  5. Replace the system board.*

I turned on my Dell Dimension 4700 computer,but the amber light started to blink . I held the start up button for 5 seconds and the light went out. I tried to start it up again and got the same thing,...


Vaughn it sounds like the power supply is going bad, try another known good working power supply. If that doesn't work then the motherboard would need to be replaced. If the power supply isn't giving the correct voltages that could cause the computer not to turn on. If the motheboard isn't able to convert the voltages properly then the motherboard could be faulty.

I have a shap lcd computer monitor and when i plug it into my computer and turn the power on, the little green power light comes on, screens back. and after 5-10 seconds the light turns orange and blinks...


It could be your monitor is fine. It simply goes to a cycle when its turned on and does not detect any signal coming from your CPU, it simply goes on standby mode (hence the darker image and orange/blinking light.) have you checked the computer (CPU) part?

Blinking red lights on startup


4x red blinking light on this system means it's "CPU thermal shutdown" this is done when the cpu fan fails to cool the cpu and the computer shuts itself down to keep you from burning up the system.
This could be caused by dirt, hair, dust in the cpu fan or heatsinc or because the fan has failed.
you can blow some canned (dry) air through the fan and heatsinc undernieth it and try to clean it. most likely you will have to take it off to clean it thoroughly or replace the fan. It is about a 15-20 dollar fan and your local computer shot or neighborhood computer guru can replace it in 10 minutes, so dont let then keep your computer longer than a day.
If your computer savy, remove the case, inspect the fan while the computers ON to see if it sounds weird or is not coming on at all. it has usually two retaing clicps the can be difficult to remove with the power supply in the way. so be ready with a philips head screwdriver and a notebook to write down anything you dont want to forget to put back. If you decide to tackle it, post again here after you check the above mentioned things and ill get you a detailed breakdown of how to do it. It real is not too hard.
Regards..

Power light blinking yellow after sitting a while


Unplug computer, disconnect all usb/monitor/internet, open it, hold power button until green led on the inside on the motherboard turns off, pop out the BIOS battery (looks like a big watch battery and use a small flathead screwdriver to depress the spring lock on one side), plug in computer, hold power button for about 20 seconds (must reset BIOS or something), let up on power button, wait 10 seconds and push power button. The computer should turn on. Wait for it until activity seems stable (1 min. or so). Push powerbutton to shut off.

If this has worked you have proven that it's not the power supply (it turned on).

Go buy a new battery (CR2032 3 volt). Unplug computer, open it, hold power button until green led on the inside on the motherboard turns off, pop in new battery, plug in (you should notice the power button blinking amber again), hold power button until it stops blinking (about 20 sec....again must reset BIOS or something), wait 10 sec., push power button. the computer should turn on. Wait for it until activity seems stabe (1 min. or so). Push powerbutton to shut off.

Now, close case, plug in all usb/monitor/internet/etc. Power up computer. You'll get an internal floppy drive error. Push F2 (maybe F1) to get into the BIOS settings and go to "drives" and turn off the internal floppy. Save and exit. The computer should boot properly now.

This seems to be a big problem with the e510, my theory is that this one small battery is the root of most of these failures (as these computers usually fail after 1-2 years), not the power supply or the motherboard (heck, when you replace the motherboard it comes with a new one of these batteries...a several hundred dollar piece of hardware, with a $5 battery that will actually fix it).

it all depends on the number of flashes , pause, repeat.
Since the problem did not indicate any beeps her is the following info


Power LED blinks RED 2 times, one every second, followed by a
2-second pause. = Processor Thermal Protection Activated


3 blinks 1 second apart = Processor not installed (not an indicator for a bad processor).

4 blinks 1 second apart .= Power Failure (power supply is overloaded)

Other possibilities are:
5 blinks 1 second apart No memory
6 blinks 1 second apart No graphics
7 blinks 1 second apart System board failure (detected prior to video)
8 blinks 1 second apart Invalid ROM
