My gateway profile 5 won't turn on. Checked plugs


Try to power drain it. Unplug all the power related devices that are connected, like a monitor data cable or external printer, just unplug all the cables in the back after you shut down your computer, press the power switch of your computer and keep it pressed for about 45 secs, release it, plug everything back and check it if its working. As well double check if that particular socket is usable, plug something else in to see if its working.

MY COMPUTERS front and back green light is flashing green


you can remove your side cover,and unplug everything from your power supply. then if you plug in your computer and the light still flashes it's your power supply. If not it's something that it is powering. Most likely it's your motherboard. I had this happen to me when there was a power surge/ outage and my computer wasn't even on.

I have an HP tower that won't power up...there is a green light on the back that steadily flashes unless you unplug the machine-then it slowly stops flashing. The unit is receiving power, however, neither...


the power wires are connected to the motherboard?
Is the switch working correctly?
You can check that by opening the box/case, look for the 2 pins where the power switch is connected (with letters PW) and touch both with your screwdriver. If the computer turns on, your switch is bad. Im not responsible if you touch other pins and kill your computer. Has to be the power one.

Countinuous flashing green light. wont turn on


its in standby mode unplugg the computer from ac wait 30 mins and re hook Ac . the try tuning it on . when screen come up go to set up mode and force it into bios then reboot as see if it boots normally. if it does the your ok . it not it means its time for either a new power supply or a newcomputer. MTBF mean time between failures = total operating time your computer has been on.

Dont leave computer on all the time. this lengthens the MTBF.

Blinking amber light with green 4 light


If the power light is blinking amber, the computer is receiving electrical power, but an internal power problem might exist.
Try, unplugging the power cable from the pc, and reinsert it, if this does not help try a differnt power outlet, if this dont help, open the computer, take the power Molex conector out of the mother board and try turning it on, if this dont help, take out the Memory modules and reseat them, if this dont work you may want to ring up dell support.

Hope this helps!

Reboot


make sure you unplug the computer, check to see if your memory is in right and in the right place. plug back in and restart. unpluging each time helps. the motherboard could be bad and or the power box, check the cpu chip to make sure it's in right, take out the modom and try it. sometimes a card might make it not come on, *********** board is not comeing on, look to see if there are any lighs that come on, and then go off, the momory could make it not work. I have had them go bad on me. and it makes the mother board shut off, and you dont get the moniter to work.

Power Green Light Flashing HP Desk Top PC m7250n


During a power outage their is a surge when power come back on the grid (surge can be caused by lighting strikes akso). This surge trips the internal procters inside the power supply to protect the Mother Board, hard drive, processor and fans and any device that pulls wattage from the power supply. Since all these power using devices are trying to pull power at the same time to boot the computer back up one ends up with a loop of surge thrugh the power supply with a protective trip, reset, surge again and trip again. This will continue in this loop as the computer is trying to boot all the devices at one time (Mobo, Hd, processor, cooling fans and other devices). Simoly, more power wattage is being demanded than the protectors will allow at one time causing a protective shutdown followed by a restart followe by a protective shutdown in a continious loop.
The normall sequence for a boot is to boot the board, processor and fans followed by a boot of the hard drive, and other boot devices once the board is energised, NOT all devices at the same time, as this results in an overload and trips the protectors. This protective loop is indicated by the blinking light as the power is turned on and then shut down for protection as the wattage pull is over the demand that the protectors will allow.
Blinking light indictes you are in the protective loop.
SOLUTION: 1. Disconnect the Mother Board connector, with the computer unplugged, this will allow the power supply to reset at maximum wattage upon reboot.
2. Disconnect the Hard Drive power connector and ay boot device power supply cables, this will allow the Mother Board, processors and fans to boot without an overload of the protector inside the power supply.
3. Plug in the computer and the indicator light will be solid green indicating that it is reset and out of the loop.
4. With the computer pluged in and the Power Supply fully energised, plug in the Mother Board. The computer will now boot, and the processor fan will come on and the cooling fans.
5. After computer has rebooted, shut the computer back down and connect the Hard Drive power cable and any other power cablis that were unplugged.
6. Reboot with all cables connected and you are up and running again.

POWER SUPPLIES HAVE AN INDICATOR LIGHT FOR A REASON.
REMBER - BLINKING LIGHT IS AN OVERLOAD OF THE PROTECTORS AND ELLIMINATING THE OVERLOAD SOLVES THE PROBLEM AND THAT THE POWER SUPPLY IS WORKING AND CONVERTING POWER.
NO LIGHT MEANS NO POWER OUTPUT AND THAT INDICATES THE POWER SUPPLY IS NOT FUNCTIONING AND NEEDS REPLACED.

Hope this helps everone with power outages and lightining strikes. It is a rather common problem and can also occure when building a computer and one missmatches the power supply with the board wattage needs. If the board wattage needs are greater than the power supply output you will get stuck in a potective loop eventually. WHEN BUILDING A COMPUTER ALWAYS MAKE SURE THE POWER SUPPLY CAN PRODUCE MORE WATTAGE THAN YOU CAN CONSUME AT THE MAXAMUM LOAD.
Have a great computing experiense.
