This may point to a couple of things. One is the DC adapter and the other may be the power jack or the power board inside. The jack on the laptop can wear loose. You should notice that the power cord is sloppy or moves and that the power led will flicker if this is the case. The power board does fail but it rather uncommon.

The dc power adapter (brick) might the culprit. To check you need to use a voltmeter. It takes a few seconds to check and you would know if it is good or needs replacing. Just trying to think who to suggest you take it to that would have a meter. Battery stores or electronics places should. A computer store with a tech who has a clue will have one. If there get no volts then order a new one in. If you get power at or above what it is supposed to do (printed on the label) then the problem is the power board inside. This is a bit of a pain to hunt ths down but is how you have to check it.

If it is the powerboard you need to get a repair estimate. You don;t have your model etc listed so I can't tell you the price. Some will have the power section built into the main or motherboard others will have a seperate little board. Depending on how new or old it is you may pay $35-$50 for a power board and $125-$300 for a new mainboard plus labour.

A power jack is worth $10-$90 plus labour.

My bet would be on the power brick, followed by the jack. Those are the two very common causes. The power jack on some brands is all I would look at others are a bit better.

Emerson emp287c-4 wont charge with usb


Having same issue, battery will not charge. Can't even use it unless its plugged into my computer the whole time. Followed the charging instructions, "turn power switch on and then use the usb cord provided to plug the device into the computer." I do so and it reads that it is charging, however the bar never goes to the green charge symbol. It said to not let it charge past 8 hours so I always unplug it before that. Even tried the recommended 3-5 hours and still I turn it on and it says right away battery low.

I always get plugged in not charging when i charge my laptop even when it is not fully charged


If the laptop works fine off the power cord without any problems then your power cord is ok, but if the battery is not charging then the battery is probably dead and needs to be replaced. Batteries only have a useful life, and when it's over they have to be replaced.

If the laptop does not work with the power cord then either the power cord is bad or the DC Power Jack where the power cord plugs into the laptop. If either of them is bad the battery will not charge.

Check your DC Power Jack which is where the power cord plugs into the computer. Take an ink pen and push the tip inside the jack and see if the little pin wiggles, if so the jack is bad. You'll have to take the laptop apart to fix it. Most times it is soldered onto the motherboard, so you will have to desolder the old and solder a new one.

Not powering on


Computers don't power on for one of the following reasons.
1. Bad Power Cord
2. Bad Power Supply that the Power Cord Plugs Into on Desktops but on Laptops it's call the Internal DC Power Jack
3. Bad Motherboard.
If you see no lights at all when you plug in the power cord and press the power switch then it's a problem with one of the 3 above.

Sometimes you can have something as simple as static charge buildup that is causing the computer not to start. Here is how to eliminate the static charge problem. Remove the Power Cord from the computer or Laptop. If you have a laptop also remove the Battery from the laptop. Press and hold the Power Button for about 30 seconds. After 30 seconds, plug the power cord back in (don't plug the battery in if it's a laptop) and see if it boots. If it's a laptop and it boots then you can plug the battery back in so that it can start recharging.

Hello,

There are three possible reasons why your computer is experiencing this power problem. What you need to do is to isolate the component that's causing it.

These are the parts which should be checked:
1. Power supply
2. Battery
3. Motherboard of the laptop.

Here's the procedure that you have to follow:

1.
Remove the battery from the computer.

2. Power the computer up with the power cord only without the battery on it.

3. Check if it works perfectly without any problems even if the battery is out. If it works, then, the battery needs to be replaced. (Note: Batteries are disposable parts. They usually die after 2 years of usage depending on how you use it.)

4.If no go even without the battery on it, check the ac adapter or cord if there's a light lit on the box of the cord. If no lights on it, double check the connection. If connections seem ok but no power, then, replace the power cord.

5. If power cord seem fine, check the hole in the computer where you plug in the cord. What you need to check is if there are any sign of damages. Wiggle the cord and see if there are lights lit in the laptop.

I hope this help.

Hi

Can you please try to leave laptop switched off
plug in laptop and leave until the light on front goes green or at least 2/3 hrs

then unplug power cord
switch on laptop and use it or leave it until it looses all power and switches off

then recharge until green

when battery is fully charged always un plug and use on battery power
until it reaches about 10% before recharging

some people even remove their battery to preserve it if they always use power cord

if this does not sort the problem please come back to us

many thanks

There is no power from the battery or the adapter and the laptop does not recognise the adapter is plugged in. there are no lights coming on and the power button is doing nothing


Your battery maybe out of charge. Thats why nothing happens when you press the power button. The battery may not be charging because the power cord might not be working. Try another power cord.

Try removing the battery and plugging the power cord and switching on the computer. If its the problem with the power cord the computer wont start. If it starts, the power cord is working fine.

hello

shut down computer - unplug power cord from laptop - remove the battery from laptop - plug Ac adapter into computer and Ac outlet (wall)
turn on computer
if computer does not turn on, replace the AC adapter and cord - then place battery back into computer
plug in new Ac adapter and cord - recharge battery - if orange light stays on after 4-6 hours of charging battery, you need new battery as well - replace battery, charge it up and it should be fine

if you have attempted these steps before and no change occurs, then you may have issue with power connection in computer - locate a service centre to replace power connection on computer

Let the battery power down, plugged back in and now computer will not come on at all, took battery out, nothing, not even the little battery flash light, even tho power cord in and blue light around cord


Need to check the power cord to see if it is running at 19.5 fisrt. The power cord may be your whole problemand it cheaper than the other problem I see.
If power cord is ok take battery to the battery store to check it's cells. it sounds like to battery is bad. but the power cord should still bring the unit up. If the battery is ok and the power cord checks out the charging unit is bad and is costly.

Battery indicator flashes even when plugged in to electrical plug, computer recognizes plug-in. Computer will not run with power cord.


The battery indicator flashing when plugged in to electrical plug means your battery is completely dead and won't charge. You're computer should run with just the power cord. Your power cord most likely needs replacement.

If you know anyone with the same model of laptop ask if you can borrow their power cord and/or battery to test it out. It is rare for the problem to be the motherboard, though it does happen.

It may just be the power cord at fault as the computer should run without the battery, so you should replace the power cord, as it is probably the reason the battery is completely dead.

If the battery is at least a year old I would replace it since they generally don't last too much longer than a year.
