There's no way to repair batteries once they stop holding a charge. you will need to buy a new one.

Lenovo z570 not powering on


Measure the voltage at the AC Adapter plug, and see if it is within 5-10% of the rated voltage. If the voltage is not correct, then the battery will most likely not be charging, and the system will drain the battery and die in the middle of what it was doing...booting in your case.

You can tell how much voltage is remaining in your battery and if it is charging by checking the blinking of the battery status light.
Download the Hardware Maintenance Manual here:
http://download.lenovo.com/UserFiles/UserGuide/en/User%27s%20guides%20and%20manuals/Z370&Z470&Z570/Lenovo%20Z370Z470Z570%20Hardware%20Maintenance%20Manual%20V1.0.pdf
and go to page 30 and look at item 7 under battery status for blinking light meaning.
1. Blinking amber: (500ms off/1s on)
The remaining power of the battery is less than 5% of
its capacity.
2. Blinking amber: (100ms off/3.2s on)
The battery is being charged with the remaining
power between 5% and 20% of its capacity.
3. Amber: The computer is operating on battery power with the
remaining power between 5% and 20% of its
capacity


With the AC Adapter plugged in, and giving the correct voltage, If you are getting 1. Blinking Amber (light on for 1 sec, off for 1/2 second), then the battery is not being charged. Could be AC Adapter, Battery or Battery Circuit on motherboard. If the light is solid on 3. Amber, then the battery is not charging, and is draining.

Also make sure the power socket on the laptop is not loose or damaged. If it is, then it will need to be replaced.

I hope this gets you in the right direction.

Toshiba l505.no power,blinking light battery for 6 time then stop ?


Can only guess your battery is bad. Try charging. If you have the only other way to find out is to check the battery and the voltage with a multi-meter and if it has a charge. If so, then it's a problem in your laptop

Battery charging LED not lighting up when the laptop is put for charging and the laptop is not getting on.


probably the charger is not working right. Please check with with a spare charger or borrow with someone to check. if the laptop switches on the charger has the problem. Buy a new one with same specification to avoid further problems. and please dont forget to vote my answer with the thumbs up symbol below. thank you.

Your battery is bad and causing a problem. most likely it is feeding an incorrect voltage into the computer. replace teh battery and it should fix the problem. If you have already replaced the battery with a new one the charging system is faulty or the AC adapter.

When the adopter light is blinking. when the net-book is turned off means that is charging, but if the light remains for a lobg period of time there is something wrong with the battery or the charger.

Here is small tool Imtec Battery Mark designed to test the battery laptop life. You can run laptop battery test in two modes (fast and normal) and Imtec Battery Mark will provide full assessment of your Laptop battery at the end of test.

The dead battery charger means the charger can not work : can not charge the laptop battery or can not run the laptop. When our laptop battery can not charge, we must check the battery and charger state. Now let me list the steps of test our battery and charger below.

Make sure the powerbook g4 battery charger cable is plugged in and the output is to power.

Look closely at the battery. Is there corrosion or leakage? If so, replace the inspiron 6400 battery immediately.

Test the charger. For DC chargers, a voltmeter set at 25 VDC and touch the contacts with the probes. The meter should read about more than 1 V Evaluation of the shipper. If the reading is zero, change battery catheters.

Testing a AC charger through the establishment of a voltmeter to 25 VAC. Tap the contact probes. The transformer in the charger is bad if you get no reading.

Check contacts. These are strips of metal or points in the appliance and charging cradle. With the batetry charger unplugged, clean with a cotton swab. Use a fine emery board to remove visible corrosion.

Respected i have d610 the charging light blink 3 time red then green and not changing the battery


First of all, 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.

Acer notebook: But its not charging, 0% and a big X on the


You may have a bad cell in your battery pack (hopefuly its not the powersupply). First remove the battery from the underside of the laptop and replace it. Try charging again.

Check the output of the powersupply with a multi meter and ensure it is providing the proper voltage.

If the PS is good then go on ebay and order a new battery from Hong Kong for cheap (thats what I did :)

Hope this helps,

Cheers,

If you plug the charger into the computer without the battery and the laptop runs fine, then I would suggest to you that your battery is failing and will no longer accept the charge. On the other hand if the laptop will not stay running or acts strage and the screen dims and gets bright, then I would suggest to you that the charger's built in voltage regulator is failing and will damage the laptop if it continued to be used. A bad charger will also permenently destroy the battery condition.
