Take the battery out, plug in the charger and see if the laptop works. If it works, the battery may be the problem. Check the AC Adapter
Check to make sure the adapter is plugged securely into the wall outlet, connected firmly to the adapter box and to the back of your laptop. Most AC adapters have a little light in them on that rectangular box in the middle of the cord that lights up when it's getting electricity. If that light isn't on, try a different outlet. Check your fuse or circuit breaker box and plug a different device into that outlet to make sure there is power to it. If it still does not light up, your adapter could need replacing. Also check the adapter box for signs of warmth, as it will generate heat when it's plugged in. No heat means no power.

Remove the Battery Sometimes it's as simple as a seated battery. Remove the battery entirely and clean out any dust, lint or hair that may be clogging the connectors and preventing a proper connection. Reseat the battery securely and make sure the little locking pins that hold your battery in place are securely fastened and there is no movement. WARNING: Before you start troubleshooting remember that you are dealing with electricity that can KILL. http://www.kitchentablecomputers.com/static.php - rules
Only work inside the computer case when the power has been switched off and disconnected. Never open the power source. Some of the below steps recommend removing physical parts within the computer. While in the computer it is highly recommend that you be aware of ESD and its potential hazards Check all power and data leads from motherboard to hard drive and all of your cd/dvd drives make sure connections are secure dust free and not faulty computers need all power and data to travel through every working device and to finish its cycle so any faulty lead will end in computer error or shutdown / fail to boot or to reboot on a cycle make sure your computers RAM modules are securely seated with no dust in the sockets also the Cmos battery has charge and seated with no dust in the sockets. some Motherboards Cmos batteries are soldered in.

Hope this helps.

SOURCE: 2002 IBM ThinkPad T23 battery problems/won't run without power

It doesn't look to me that you're doing anything wrong there.
Was there a specific installation requirement for the battery?

I recently changed my battery on my IBM/Lenovo and all that was necessary, was to let it charge fully before usage.

If you say your battery was charged for "a few days", then I assume there is something wrong with the battery. Next to your taskbar you should see a battery symbol. Double-click on it and you should see the Thinkpad Power Manager. If there is a tab called "Battery Information", see if that gives you more details. Look at the Manufacturing date!

If you really can't run the laptop without being connected to a power source, I would definitely return the battery or at least call the vendor. If your computer is running fine otherwise, there should be nothing wrong with the machine itself.

If you can take a screenshot of that battery information window adn post it here, I am happy to look at it.

PS:
You're doing the right things when you try to use the laptop without an external power source - that's the whole idea, isn't it?

SOURCE: Can I power my laptop through th usb port

I know you've either fixed your problem, or thrown the laptop out(still a "fix") but for posterity, and for anyone with a similar problem...

There are two answers, depending on your laptop.

First, NO, there is currently no way to charge your laptop battery by putting power into the usb port.

There ARE commercial external batteries. sadly, they will connect to your failing power-socket.(see http://www.laptop-battery.org/Power/External-Batteries/ENB003L.html)

If your laptop has a external battery charging dock, for spare batteries.... you could go that route.
you'd probably still want to follow the last suggestion.

GET IT FIXED!
Seriously... anyone with fairly good soldering skills can probably fix that powerjack. It probably pulled/pushed the traces off the main board and will require superglue, solder, and maybe a bit of fine wire, to fix. The biggest obstacle will be the dissassembly, and proper reassembly of the laptop case. It'll take a while, but once fixed, should return your laptop to 100% functionality.

I have saved 3-4 laptops with this technique. One, I even swapped the power jack to a more common size. This was to allow the use of a non-proprietary power brick(the original had fried itself).

SOURCE: My laptop is a Sony Vaio PCG-6Q2M with Power and Battery Problems

The best advice would be to update the BIOS and then go to the BIOS utility and restore the settings back to default. This might resolve the issue if it is software related. If not then visit the manufacturer's website and download the latest chipset drivers. Restart.
Try using a different power adapter of the same kind and check for the issue.
Turn off system and remove the power cable and battery and press the power button for about 30 seconds to power drain the system.
Turn on and check.
If not the main board itself is the issue for which I would request you to contact the manufacturer.

SOURCE: Hellow Dear, My acer aspire 4935

First, you need to make sure your power adapter is providing enough power to both run the laptop & charge the battery. A very good way to do this is to compare your laptop voltage & ampere requirements (written on a sticker on the bottom of the laptop) with the voltage & ampere ratings of the power adapter. Voltages should be the same, or the power adapter's voltage about up to 0.5 volts more than the laptop's voltage rating. Amperage of the power adapter should be at least equal to or greater than the laptop's rating. It should never be less than the laptop's rating, or else the power adapter will be providing insufficient amperes to charge the battery. Of course, the power adapter's nominal amperage might be ok, but it degraded on usage. You can verify this by testing using a good or new power adapter.
If the battery did not charge using the new power adapter, take the battery off the laptop, & using a dry tooth brush, scrub in between the fins of the battery connector on the motherboard & on the battery it self, then put the battery back into the laptop & try again.
If this still did not resolve the problem, then the battery itself could be bad. Try it on another laptop, or try a good or new battery in your laptop.
If this did not work, there might be a possibility that the charging circuitry on the laptop's motherboard is defective & needs servicing. In order to do this, the laptop needs to be disassembled & the motherboard checked for defective/burned out components in the area near the DC jack. Any defective/burned out components found should be replaced, or you might need to replace the laptop's motherboard altogether.

Top 1 to 5 tips to extend your laptop battery life


1. Defrag regularly - The faster your hard drive does its work – less demand you are going to put on the hard drive and your battery. Make your hard drive as efficient as possible by defragging it regularly. (but not while it’s on battery of course!) Mac OSX is better built to handle fragmentation so it may not be very applicable for Apple systems.

2. Dim your screen – Most laptops come with the ability to dim your laptop screen. Some even come with ways to modify CPU and cooling performance. Cut them down to the lowest level you can tolerate to squeeze out some extra battery juice.

3. Cut down on programs running in the background. Itunes, Desktop Search, etc. All these add to the CPU load and cut down battery life. Shut down everything that isn’t crucial when you’re on battery.

4. Cut down external devices – USB devices (including your mouse) & WiFi drain down your laptop battery. Remove or shut them down when not in use. It goes without saying that charging other devices (like your iPod) with your laptop when on battery is a surefire way of quickly wiping out the charge on your laptop battery.

5. Add more RAM - This will allow you to process more with the memory your laptop has, rather than relying on virtual memory. Virtual memory results in hard drive use, and is much less power efficient. Note that adding more RAM will consume more energy, so this is most applicable if you do need to run memory intensive programs which actually require heavy usage of virtual memory.

I got a dell latitde d505 wont power on or anthing no blinking lights no noises. i plug it into the charger n the charger light goes off. can some1 please help me??


Sounds like you may have fried your dell latitude. I have seen many laptop's fry and it is nothing you did, but they just go sometimes.

Recomendaitons:
Take the battery out of the laptop.
Plug the charger in.
Hold the power button for a minimum 10 secs (which will reset the power options)
If there are still no lights than it is your cpu
If the computer turns on then you have a bad battery.

When batteries are bad or dead, the computer tries to run off of the battery befor the charger, it switches over to the charger after your OS has booted. In that case you can just order a new one no big deal, but if your cpu is fried then there is no hope for the laptop. :( I have lost four laptops because of this, so for your sake I hope its the battery or the GND Drain.

Also possible that the GND's drain on your board is too short and Gate 4 is driving low. To fix this you have to remove a SMT ceramic cap, which is located opposite side to the power connector, almost under it. I would guess at 1206 or slightly larger and there is an 0402 cap just next to its bottom pad at 90 degrees to it. A couple of Dell Latitude d505 have had this problem and can easily be fixed, but must be cautious and know what you are doing. I would advise seeing a professional.

Please don't forget to rate :), Thanks!

My laptop lenovo 3000 N100 battery has a problem.. therefore i purchased a new battery but the problem with this battery is that when i use the battery it runs the laptop for 10 -15 mins and then with a...


My Dell laptop has a power problem.
d600a.jpg?w=300&h=258
The Dell Precision M20 Battery stops charging when I move the power cord on the DC adapter. When I start moving the cord left to right, the power LED light on the front goes on and off and the battery charge LED goes on and off too.
dell-precision-m20.jpg?w=300&h=225
I removed the precision m20 battery and tested the laptop again. The laptop starts fine from the DC adapter when the battery is removed, but as soon as I start moving the power cord the laptop shuts off. It looks like the laptop looses power immediately.
If you have a problem like that, most likely it’s related either to the power adapter or the DC-IN power jack.
First of all, I tested the laptop power ac adapter with a multimeter. The power didn’t cut off no matter how badly I moved the cord. The power adapter output voltage was 15.45VDC all the time. That means there is nothing wrong with the power adapter and most likely there is a problem with with the power socket inside the laptop.
Now I’m going to test the power socket inside the laptop.
In order to access the power socket I had to disassemble the laptop and remove the top cover assembly with the display.
You can find disassembly instructions for many HP, Dell, IBM, Lenovo, Sony and Toshiba laptops in these service manuals and guides.
In the laptop I was fixing (Tecra M2) the power jack is attached to a DC-IN harness and this harness can be unplugged from the motherboard.
As you see, I removed the DC-IN harness from the motherboard, plugged in the power adapter and tested continuity with my multimeter as it shown on the picture.
When the power cord is still, the voltage output is 15.45VDC, the same as on the plug.
But as soon as I start wiggling the plug inside the jack, the power cuts off and voltage goes to 0. It means, the power harness is bad.
The problem was fixed after I replaced the defective DC-IN harness with a new one.
In some laptops the power socket (DC jack) is soldered to the motherboard.
If the battery stops charging when you wiggle the power plug inside the jack, either you have a bad power adapter (test it with a voltmeter) or the power jack is broken or loose.
You cannot simply unplug the jack and replace it with another one. You’ll have to unsolder the old jack and solder a new one back on the motherboard as I described in this post.
If the power jack is not broken but loose (not making good contact with the motherboard) you can resolder the old jack without replacing it with a new one.
If you want to buy a new one,you can see more information from http://www.udtek.com

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.

Power cuts out


whenever you plug the adapter to your laptop, there is a small pilot light which lights up. if it doesn't light up that means your adapter is not charging your battery. if it does, then maybe you should change your battery. just a little tip : it would harm your pc if it often goes off unexpectedly or improperly shuts down.

Sony Vaio ac adapter submerged


If the ac adapter was plugged into the laptop at the time may be bad news. Unplug AC adapter, take out the battery and hold power button for 10 seconds. Then connect AC adapter and hit power. If that doesn't work put battery back in without ac adapter and hit power button.

If neither test works bring to repair center for diagnosis. Best case AC adapter would need replacing. Worst case Motherboard fried.

Thanks
