    its a laptop packard bell easynote r4650, the supply is fine

  • clvwalsh Feb 03, 2009

    Thanks for your reply Sublimation

    Symptoms:
    When you plug in the power adapter and press on the power button, there
    is no signs of life at all. The laptop will not make usual noises, LEDs
    will not light up, the fan will not spin, the screen is blank and
    black, etc… In short, the laptop is dead.

    Yes I tried plugging it in so the battery can charge. It has been plugged in since yesterday and it still will not power up.

    Do you think it might be the DC power jack or the Motherboard ?

    Laptops are not my field of expertise, however it's either that or the Power Supply. There is the possibility that your motherboard has a jumper which has to be in a certain position when the power button is pressed before the system powers on.

    No, this is not the cord to connect the power button to the motherboard, it is a jumper on the motherboard which is used to reset the CMOS. If the jumper is missing or not in its proper position the system will not start.

    Sorry that I can't help you all that much here.

    Have you tried plugging it in so the battery can charge? Although you haven't been using it, the battery still discharges power to the system. After a while of not being charged the battery will run out of juice and will have to be recharged.

    If the computer has no power , no lights. no anything then the first place to look is at the power supply. First make sure no-one trned off the switch on the back.Should be on 1 not 0

Dell OptiPlex GX110 hangs at post


Test your PSU or replace it if your power supply units fan is not working your PSU is faulty

One bad lead can cause a computer to continue on a cycle or to shutdown or fail to detect/ boot up a computer hard drive


Test all leads that attach to your hard drive including electrical extensions,IDE,SATA

the leads from your MOTHERBOARD TO YOUR HARD DRIVE make sure they have a secure connection and are not faulty or just replace them they could be faulty

make sure all leads that are attached to your drives dvd\cd 3 1/2 inch floppy have secure connections and are not faulty even the electrical extensions or just replace them they could be faulty a computer needs its connections to continue its cycle and have an end so any faulty leads will end up with a computer error

even something as small as a faulty electrical extension or fan lead can cause you problems

computers need all of the data and electrical current to travel through every working device and to have an end to be able work properly


motherboard and a hard drive any leads between them will fail before your motherboard or your hard drive if its a flat ribbon 40 pin type IDE replace it this will be the first to fail

check all electrical power input and extensions make sure they are securely seated even the cd/dvd floppy drives need to have current go through make sure these drives are working


also check the Cmos battery and computer RAM modules make sure they are securely seated with no dust built up or in the sockets on some motherboards cmos batteries are soldered in

check you CPU make sure its securely seated and has thermal grease

hope it helps

Start with pulling the battery and power, then hold the power button in for about 30-40 seconds. Then plug the power back in (still no battery). Try to power up the computer. If it boots, shut it down and put the battery in and try again. If it boots the issue was cleared. If it boots with the power cord but not with the battery added, you have a battery issue.

Hope this helps

If you have access to a voltmeter I would check the power supply first. Take your cover off, and lay the computer down on its side, open side up. You should see a cable that provides power to your hard drive with an extra one that is free. The color of the wires are red, black, and yellow. Put the meter on DC volts and place the black lead in the black connector and put the red lead in the red connector. You should read +5 volts. Now move the red lead to the yellow connector, you should read +12 Volts. If either one of them is not correct, your power supply is bad. Replace it with a like type or one with a higher power rating to handle upgrades in the future. If the power supply is okay, then with the computer still on its side, look and see if there is a LED next to the CMOS battery. (A flat looking battery a little smaller than a quarter). If this is lit then you have power through the motherboard. Turn the computer back off and replace the CMOS battery. You may also try and reset the CMOS settings. There should be a jumper next to the CMOS battery. With the power still off, pull the jumper and place it across the other open post and leave it like that for about 15 seconds. Now put the jumper back in its original position, and put the new battery in. Turn the computer back on and see if anything is different. If same symptoms, then your best bet is to take it to a certified repairt person. Hope this helps.

Beeps 2 times & a warbling noise when trying to boot up - unplugging power lead & pressing ON/Off button & reconnecting power lead starts up OK - but it can be OK for several days & then repeats the p


The Cause of Problem:

The Power Buttons electrical circle sometimes just braked it by one of sensors and the result is the 2 beeps and Power Supply is in protected mode error.

The whole computer is turn off but the power button is turn on and this is the nub of the matter. Because if you want turn on the computer you can't because already turn on but just the Power button and you can't do anything.

The solution:
You need just change the Power Supply and don't do anything just the power cable put into the Power Supply after turn off computer.
Finaly change back the Power Supply.

Battery not running


Possible that whoever replaced your battery sent you the defective one back. Note the serial and model numbers on the battery, then request another one. When you receive the replacement, do a full recharge. Most new batteries come already half charged. Even in this state, take time to fully charge it (between 4 and 8 hours depending on the type and model). Then try running it on battery power. If the charge holds more than 2 hours on a new battery, youre good; less than an hour new, its defective. If after all of this still not resolved, request the company honor their warranty (usually a limited one year with purchase).
