Laptop won't turn on

I took my laptop in to get looked at because I was getting absolutely no power. The battery was fine and so was the ac adapter. They tell me its the mother board. Because I don't know a blessed thing about it I am not sure if I being told this is the problem so that I can replace it. They said that it would be cheaper to replace the whole laptop than to replace the mother board. What should I do?

    I have no geek friends... Not techy geeks anyway...LOL ;-) I will try the second opinion first. Thanks so much for your help!

    I have the same problem. I found out that its the female part inside of the laptop that connects the motherboard to the ac adapter. There's a metal connector that leads into the motherboard from the female part, its broken, its soooo small that you can't find it. I, luckily found it by accident. I fixed it by soldering a bead connecting the broken pieces, if you're going to try be very careful. I have 2 gateway laptops and they both have that issue, I think gateway does it on purpose so that we could spend more money either trying to fix it or spending money to buy another laptop...ITS Bu!!Sh!T!!!!!

If you know someone who has the same laptop, try testing your battery and adapter on that laptop just to make sure that they are working fine. If not, it might be a motherboard issue and replacing a laptop motherboard would cost a lot.

If you have a geek friend, ask him/her to use the multimeter to check that the power supply is delivering the correct voltage to the motherboard.

If you dont, try to get another opinion from another place to check if they say it's the same problem.

I have an ASUS laptop which has been shutting down for the past 1 hour. It has little battery left so I have disconnected pwoer hoping it would go flat.


Asus WHAT laptop?
What is the model number? Bottom of laptop.

Two, is the laptop dirty inside?
If you have never had it cleaned, it is.

Three, "It has little battery left so I have disconnected power......."

Shouldn't have low battery power, if the thing is plugged in.

Four, have you tested the AC adapter's (Charger) output voltage?

Five, is the DC Power Jack in good condition?

[DC Power Jack (DC_IN), is the jack on the laptop that the AC adapter plugs into ]

Could be.........

A) The Battery is older than dirt........
("How old is that battery?
Lemme tell ya,.......that battery is so old that.........")

Battery needs replacing.

B) Power MOSFET's are going south for the winter, and didn't invite you, or the laptop along.

("Pssst..........let's go to the Bermuda's, but xnay on telling the laptop, or dlemaistre)

They control whether the Battery is to have a trickle charge, or full charge; OR, whether the laptop is to just run off of the AC power, and not the Battery.

(Actually the AC adapter {Charger} is a converter. Converts the AC electricity from the home, or business; into DC Voltage.
So it should be stated, ".......OR, whether the laptop is to just run off of DC power from the AC adapter)

Air is used to cool the hardware components inside the laptop.
The two hardware components that give off the most heat, is the Processor (CPU), and graphics chipset. (GPU)

When the Processor overheats it turns off. (BIOS turns it off)
This is a fail safe feature that is built-in.
Keeps the CPU (Processor) from burning up.

So the laptop could be turning off, because the Processor is turning off; due to the laptop is dirty inside.

The battery could be low on charge, because it is old; and not keeping a charge.

OR,
Power MOSFET's are bad, and battery is not being charged up.
Also no power TO motherboard of laptop, because power ends at the DC Power Jack on motherboard; and rest of motherboard isn't receiving power.

Using HP Pavilion dv6000 series, and Pavilion dv9000 series of Notebook PC's; to explain,

http://mayohardware.blogspot.com/2010/04/important-parts-on-dv6000-and-dv9000.html

So,.......
1) Is the laptop dirty inside?

2) Is the Battery more than 2 years old?

3) Does the AC adapter (Charger) prove to be good?
Putting out the required Voltage?

4) If the DC Power Jack on laptop, is the design that has a Center Pin; does the Center Pin move around, when you try to gently move it with a tool?
(BATTERY removed)

No power when plugged into ac


When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

Ifthe laptop battery is more than 3 - 4 years old then the battery could be wornout. Rechargeable batteries have a finite number of charge and discharge cyclesand will lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up atall. ORThe battery shows a 100% charge but when the adapter is disconnected thebattery drops off to zero capacity in a very short time.

You may have a DC connector problem:

Symptoms of a broken power jack
1. If you wiggle the power cord or the AC Adapter connector on the back of the laptop, the power LED and battery charge LED start to flicker.
2. Battery will not charge in the laptop.
3. Laptop runs fine off a charged battery.
4. With the AC Adapter connected the laptop appears to be dead.
No power LED or battery charge LED activity.
5. Laptop randomly powers off without any warning.

If your laptop is out of warranty, then you can fix the problem by re-soldering DC-IN jack on the system board. If it

I bought new universal adapter for asus laptop and it charges batery just when laptop is turned off


Problem description: The battery charges only when the laptop turned off. The battery charge LED lights up as normal and the battery gets charged to 100% while the laptop is off.
When the laptop is turned on, the battery charge LED goes off even if the adapter is still plugged in.
Possible cause: 1. AC power adapter failure.
2. Battery failure.
3. Broken/loose power jack.
4. Motherboard failure.
Possible troubleshooting steps and repair solution: 1. This problem could be related to a faulty AC power adapter. It's possible that the AC adapter doesn't provide enough power when plugged into the laptop. To find out if this is your problem, you'll have to test the laptop with another working adapter.Replace the adapter if needed.
2. There is a slight chance that you have bad battery. Test the laptop with a know good battery and replace the faulty one if needed.
3. The battery charge problem could be related to the power jack. Maybe the jack is broken or not making good contact with the motherboard. It is necessary to remove the motherboard and take a closer look at the power jack. Resolder or replace the jack if needed.
4. If the power jack is in a good working shape and new power adapter with battery do not fix the problem, most likely you have a faulty motherboard. Replace the motherboard if needed.

ASUS laptop AC Adapter

HP Compaq laptop won't charge/power from AC due to blown fuse


Hi there,

There's plenty of causes why your laptop would not power up from the AC adapter and won't charge the battery. Here are some possible causes and solutions to this problem:

Number one, if it's on battery power, the battery is dead or the battery is bad and number two the AC adapter could be bad. Let's roll out number one.

1. Take out the battery, remove main supply, hold power button down for 30 seconds. This will drain the charges in your

battery. Put only power supply in, do not put battery in, turn laptop on, put the battery in.

2. If the solution in no.1 doesn't solve the problem, pull the battery out, keep the battery out of the laptop for this test.

Take your AC adapter and check the voltage with a voltmeter. What you want to test for is voltage. Put the meter at 20

volts DC and take the tip, the power jack tip of your AC power adapter. You hold the black, (the negative part) of your

voltmeter on the outside of the power jack tip of your AC adapter and you put the red (the positive part) of your voltmeter

in the hole in the inside of the power jack tip of your AC adapter. Be very careful not to touch the red and the black part of

your multimeter and the power jack tips of your AC adapter together, otherwise it will create a short circuit.

After doing these procedures, if your AC adapter is good it will output a voltage which ranges from 18 to 19V DC on your

voltmeter, depending on the voltage that puts out on your AC power adapter. If your voltmeter doesn't show any voltage,

probably your AC power adapter is bad or damaged. But if your voltmeter shows up voltage, then we have to go to the

next possible cause why your laptop won't power on.

3. The dc jack on your laptop might be bad, if the dc jack on your laptop is bad or not making a connection to the

motherboard then it look the battery is bad as well, because the battery is now not holding a charge or even taking a

charge. Also, even if your AC power adapter is good and when you insert it to the dc jack in your laptop it could not power

up the laptop because the dc jack is not making a connection to your laptop motherboard in other words the dc jack might

got loose, that's why it's not making any connection to the motherboard. The only way to solve this is that you have to

disassemble your laptop, and take the laptop motherboard out and look where the dc jack is connected. After you found it,
take a file tool and file off a spot on the motherboard where you can reattach the power jack and use a wire to reattach

the power jack to the motherboard.

Hope you find this answer helpful. God bless.

this probleme is common among acer 5920, the probleme is with the motherboard that's of bad quality and workmanship. Acer should be ashamed to sell a PC with a faulty motherboard and should compensate all 5920's owners or replace with a better motherboard. 1000's if not millions are having the same probleme wich tell to anyone with a brain that Acer 5920 is a scam. good luck. x

Laptop won't run on ac power and keeps shutting down


Check that the AC power works, go to a repair shop and test a different one or have voltages checked with a multimeter.

If the AC adapter is fine, then it is usuall because AC socket solder joints on laptop are broken. In this case , it is a delicate repair, and must be done by an expert repairman.
