    Apparently this a common problem and the manufacturer needs to replace it and recall the ones out there. This is a **** device.

First check the wall socket make sure you are getting power, plug a lamp into it for instance. If there is no green light on the adapter then it is bad and you will need to order a new one from your computer manufactor.

Hp pavalion dv6550 runs on charged battery but not on adapter and does not charge the battery either. When the AC adapter is connected the blue light comes up so I'm assuming it is powered and con


Try another cord/charger with the EXACT same power specs as the original. Has the AC jack in the laptop been damaged, loose connection, due to pulling on the cord while plugged in? Try to wiggle it when plugged in to see if there is any connection. The AC jack may need replacing, if your lucky.

My Asus get no power


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.

Asus wont turn on


For this kind of issue, please follow up the following steps to check:

1.confirm the battery and ac adapter connect the laptop normally.Maybe the bad connect lead to this problem. If there are no lights when you turn on laptop, one of possible reason is that your adapter is malfunction.

2.the second possible cause is laptop dc jack failure. If the dc jack is broken or loose, you are required to replace it or repair it.

3.Another possible reason is that there is something wrong with laptop motherboard. For this situation, it includs two kinds of possibility,a failure in an electronic circuit and BGA malfunction.

For more detailed reasons and solutions, please have a look at the following article:http://www.ifitjams.com/lappower.htm

If you verify your laptop adapter is dead and you plan to order a new one, I recommend one for you on the basis of your laptop model:

Asus ASUS A53U-ES21 wont power on


In order for the AC adapter to work the battery must be in good condition, why? Because the system runs of battery the AC adapter just keeps the battery charged up while in use, if the battery is open or defective the computer will not run on just the AC adapter.

Laptop battery is not charging


Hi, this information represents a basic troubleshooting guideline. Refer to your user guide for specific charging and connection instructions. Manuals may be available online in the Support Web site of HP.

Remove the battery from the computer.
Confirm the battery contacts are free of any foreign material that may prevent charging.
Reinsert the battery into the computer.
Verify that the AC adapter cord is properly connected and plugged directly into a known working AC power outlet.

NOTE: If the battery charges correctly when the AC adapter is plugged directly into an AC power outlet, but not when plugged into a power strip or surge protector, the problem is with the power strip or surge protector and not the computer battery or AC adapter.

Verify the correct AC adapter is being used.
Ensure the AC adapter box power light is on. This will be an illuminated green light.
If the AC adapter power light is not on, the AC adapter and power cord will need to be replaced.
Verify the charging indicator is illuminated on the computer.
If the issue still exists, install a different compatible HP battery, if available.

NOTE: If a replacement battery charges and operates correctly, the problem is with the first battery.

If neither the original nor a replacement battery charges, service may be required for the computer.

I have no led light on my e1705 when i press it and nothing comes on


Things to check:
1. AC adapter cord, esp close to the brick. Does the green light come on the brick? If not, replace the adapter.
2. Reseat battery. Check the battery charge by depressing the battery indicator button on the battery. Does it have a good charge? If so, then it could be the connection to the mother board causing the issue. If not, then replace the battery.
3. If both the battery is good and the AC adapter is good then you are looking at a mother board issue.

Not charging


which green light?

light from the ac power adapter or the light from the battery?

if ac power adapter you are referring to try a diff power wall socket if ac power adapter still off then replace ac power adapter alone.

if battery light is off but the laptop works fine with ac adapter alone try updating the laptop BIOS.

if ac adapter light turns off when it plug to the laptop replace motherboard.

Battery has gone dead. When I plug the A/C cord in the light on the charger immediately goes out and won't charge battery.


try connecting ac adapter alone without the laptop, check if ac adapter light will stay green or blue.
try another power outlet using the ac adapter alone without the laptop check if the ac adapter light will stay as green or blue. if all fails replace ac adapter.

if ac adapter stays green or blue try connecting to the laptop without the batt, check if the ac adapter light will stay on, if yes then try connecting ac adapter to laptop with the batt plugin check if the light stays green. if not update the BIOS. if fails replace motherboard.

Ac adapter does not connect to battery


You either have a faulty ac adapter; a bad power supply in your laptop; a bad battery; or a blown LED indicator light.
1. If the connection is not loose when you plug in your ac adapter try letting the laptop charge for a while. (If you are using the correct ac adapter)
2. Try removing your battery and using the ac adapter. If this works the battery is bad.
3. Try a new ac adapter.
4. Power supply is bad
