Battery power not working


Hi,

Try Removing your battery first then unplug the Power adaptor from the system, then press and hold down the power button to do a power drain on your systems motherboard.

return your battery then try powering the system using battery only.
if the system still wont power up using battery, plug in your adaptor go in windows, go to add remove programs or programs and features depending on what windows your system has, once in either one of the two look for energy management uninstall it from your system then restart the computer one last time try powering using your battery only.
If still this does not work powering the system using battery try updating drivers for your motherboard go to the lenovo website consumersupport.lenovo.com for the chipset drivers download

if still nothing has changed call lenovo probably something is wrong with your motherboard or battery you may need to send the system back to lenovo for further checking.

Problem with dell 1200 inspiron power


please remove all the components like battery , ac adapter , any external device connected to system.
press and hold power button for 10 seconds and release the power button .
try to power on the system with plugging in ac adapter directly in to system .
if system powers on then connect battery after powering off the system.
if it does not powers on then remove memory, wireless card, harddrive and optical drive by following this link. http://support.dell.com/support/edocs/systems/ins2200/en/index.htm
and try to power on the system after all the componenets are removed.
if you get power light then start fixing all the component again one by one and try to isolate the faulty device.
if there is no power after all the componenets are removed then you will have to replace the system mother board.

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.*

Dell Optiplex GX280 Power switch flashes white light rapidly system will not turn on Fans do not start


Outlet - unplug the power cable and put it on an outlet on its own Power Cord - make sure you remove the power cable from the back and plug it back in to make sure you have a good connection. things that cause this blinking light: Power Supply -open system and follow cables to make sure its connected well to each part. I/O Panel - this is where the power button is at . just open the system and follow it behind the power button.the flat cable going to the mother board , disconnect it. plug the power cable to the wall and if the system starts up then the power supply is good and the the cable that you just disconnected is bad.

If it still doesn't power up remove
memory
hard drive
dvd/cd drive
and start the system.
no luck then it is the systemboard.

I have a dell 5150c with a blown nps 275bb 275w p/supply i have tried chaging it with 2 220w ones but amber light flashs indicating problem it will run off a full size power supply 600w must i get a 275w...


Any power supply should work as long as it's the proper minimum wattage. You only need to make sure that it has the power connectors you need for your system. T'here is nothing wrong with buying a 400 watt P/S or larger. Many systems have under powered power supplies if you add onto or upgrade your system. For example when building systems you need to calculate how much ram memory your system will have and you need so many watts for each gig of ram. Dells normally come with under minimum required ram so they don't put very good power supplies in their systems and when people upgrade the ram the power supplies are usually inadequate.
