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

Battery in my VAIO not recognized


The battery may be dead. How old is it? A battery has a "lifecycle" of sorts, just so many charge/discharge cycles.

AC Adapter issues Q & A.


<p><b>Laptop switching to battery while connected to AC adapter</b><br /> <p><b>Q.</b> While turned on, the laptop will switch to battery power even if connected with the AC adaptor (sometimes during boot-up, or after a while) until the battery drains out, he then goes to hibernation (the battery light is off). If no battery in the laptop, it will shut down, and the AC light will blink very fast. The battery (li-ion) will only charge up to 10%, where it then jumps right up to 100%, and will discharge from 100% to 90% then jump to 0%, go to hibernation, and fails to complete the process, shutting down. The adaptor makes a small "camera flash charging" sound, stabilizing at 19v. When charging, it repeatedly makes the "charging sound" Faulty AC adaptor? Or Faulty battery? Or Both?<br /> <p><b>A. </b>First problem: The laptop switches to battery power even with connected AC adapter. Most likely you have a faulty power jack. It's either broken or loose. It's a known issue with laptops and you can fix it by replacing/resoldering the power jack or relocating it outside laptop case.<br /> <p>It also could be a problem with the power cord. Find a multimeter and check the AC adapter. See if the power cuts off when you jiggle the power cord. If it does, replace the adapter.<br /> <p>Second problem: The battery will discharge from 100% to 90% and then jump to 0%. It sounds like a bad battery.<br /> <p><b>Battery charging light is on even when power adapter is unplugged and laptop is stitched off</b><br /> <p><b>Q.</b>The yellow light for battery charging does not go even after switching the laptop off and power jack is disconnected. Battery does not charge at all with power source connected. <br /> <p><b>A.</b> First of all, try reconnection the battery if you haven't done it already.<br />The battery plugs directly into the connector attached to the motherboard. If the battery charging light stay on even when the power adapter is unplugged and the laptop is switched off, it's either bad battery or something is wrong with the motherboard. The only way to find the culprit is testing the laptop with another known good battery.<br /> <p>Also, you can try this. Remove the battery and plug in the power adapter. If the battery charging LED lights up even when the battery is removed, most likely you have a problem with the motherboard.<br /> <p><b>Battery charges only when the laptop is off</b><br /> <p><b>Q.</b> Bought a Laptop without AC Adapter. I noticed it would charge the battery OK when the laptop was off but once in windows it would not charge the battery.<br /> <p><b>A.</b> This is very important to choose the right AC adapter for your laptop. The output voltage MUST be exactly the same. If your laptop requires 18.5V you must use 18.5V adapter. The amperage should be the same or higher. If the laptop requires 4.74A adapter, you'll have to find an adapter which provides 4.74A or MORE. <br /> <p><b>While using AC adapter alone or battery alone, laptop works. While using them together, I am getting a problem.</b><br /> <p><b>Q.</b> While using AC adapter alone or battery alone, laptop works. However while using them together, laptop LED lights blinks and the power meter for battery drops down immediately to 0% critical level, whereas the battery LED indicator says it's full. I tried to unplug the AC adaptor while it went down to 0%, then the power meter for the battery came back to normal 85%.<br /> <p><b>A.</b> There could be a few different reasons why it happens:<br />1. It might be an issue with the BIOS. Make sure the laptop has the latest version of BIOS installed, update it if needed.<br />2. It might be a software related issue. If you have some kind of power management utility installed try uninstalling it and use Windows power management utility instead. Also I would try reinstalling the operating system if upgrading the BIOS or removing the power management utility does not help.<br />3. If you still experience the same problem even after upgrading the BIOS and reinstalling Windows, most likely you have a problem with the motherboard. Apparently the charging circuit is not working properly. I assume it's not a problem with the battery. You'll have to check the motherboard in this case. <br /> <p><b>Problem with my battery. 100% to about 40% the battery discharging normally then suddenly from 40% it drop directly to 2%.</b><br /> <p><b>Q.</b> When I use only on battery, from 100% to about 40% the battery discharging normally (last about 1 hour) then suddenly from 40% it drop directly to 2%.<br />When I plug the AC cord, it won't directly charge (the charge LED is still not on). After 10 to 20 minutes it then starts to charge the battery (the indicator say that it can be charged to 100%).<br />If I turn-off the laptop and then charge the battery, it won't also directly charge but the delay is much shorter (maybe just about 1-2 minutes).<br />Is this the sign of a bad battery (when hot it can't be charged?) or maybe a bad AC adapter (not enough power to charge the battery when the laptop is turned on?)<br />Note that this symptom is always repeating when I use the laptop.<br /> <p><b>A.</b> From the first part of your complaint description I can see that you have a bad battery. The percentage might vary, but the process of discharging is the same - the battery discharges fine until some point and then the remaining charge suddenly drops to the minimum. You'll have to replace the battery.<br />I'm not sure about the second part. Probably it's a battery related problem too. Just in case check if there is a newer version of BIOS available for your laptop. If you find one, upgrade the BIOS. <br /> <p><b>The battery is 100% charged but it will die within a few minutes as soon as the laptop is unplugged.</b><br /> <p><b>Q.</b> When I unplug the power it will run off the battery, the battery icon says it is 100% charged and I have 2+ hrs remaining, but within a few minutes I get the "critical battery level" message and it will die. When I plug it back into AC power the battery charge light comes on (and will remain on for over a hour), but I will have the same problem with it dying as soon as it is unplugged. Do I need a new battery?<br /> <p><b>A.</b> It looks like you have a bad battery. Here are some behaviors typical for a dying laptop battery:<br />1. The battery charges normally (according to the battery icon) but as soon as you unplug the laptop, it dies almost momentarily.<br />2. The battery charges normally. When you unplug the laptop, it discharges normally until some point and after that point starts discharging very fast. For example it might take 10-15 minutes to discharge from 100% to 80% and then it discharges from 80% to 0 for 2-3 minutes

How long will my battery last?


Your laptop batteries will deteriorate over time whether you use it or not. Although the Li-Ion industry does not publicize this fact, your laptop battery’s clock began ticking the moment it was assembled. The elements inside your laptop batteries slowly react with each other, eventually rendering the battery unable to supply the required power to your notebook. In addition, your laptop batteries are rated to last between 300 and 800 charge/recharge cycles. It will gradually lose charge capacity rather than abruptly fail to power your notebook.

The general consensus is that laptop batteries last one to three years. While you can slow the laptop battery’s aging and loss of capacity, you cannot stop either decline. The temperature of the battery, combined with the amount and nature of its usage contribute significantly to your battery’s lifespan. You can ease the aging process with some care and maintenance.

Temperature Lower temperatures slow down the self-discharge (loss of charge while disconnected) and aging process of the elements within your laptop batteries. Therefore it follows that higher temperatures shorten the life of your laptop batteries. Leaving your battery connected while on AC power causes the internal temperature of the battery to rise. Removing your laptop batteries and storing it in a cool, dry place will help to slow the aging process. Keeping your notebook in a hot environment is also detrimental to your battery.

Amount of Usage The Lithium-Ion batteries used in notebooks are rated to handle between 300 and 800 charge/discharge cycles. Some of these cycles are used when you leave your laptop batteries connected to your notebook while on AC power. On AC power, the notebook will routinely “top-off” the battery when its charge reaches predetermined levels (i.e. 95%). Removing your laptop batteries and storing it in a cool, dry place will help to preserve some of these cycles.

Nature of Usage Li-Ion batteries do not suffer from the memory-effect (requiring complete discharge before recharging to avoid loss of capacity) like older rechargeable batteries. Regular full discharge/recharge cycles result in an increased loss of capacity per cycle. A series of partial discharge cycles are better for Li-Ion batteries than a single full discharge. You should, however, calibrate your laptop batteries routinely. Tell No One You Can Save up to 35% 3323.jpg

No battery detected


LOL, good ole Vista. I would never discharge my battery once I got it charged. I know the instructions say that, but I just never do it. Sounds like your battery is defective. Send it back.

How to charge your laptop battery properly? During the the process of notebook...


How to charge your laptop battery properly? solarroll-laptop-solar-charger.jpg During the the process of notebook using, we need no to deliberately charge the laptop battery to 100% state or fully discharged laptop battery to automatic shutdown protecting. The correct way is that charge the battery in 20% state and stop charging in 98% . If the machine has the power calibration procedure, when the battery standard-by time significantly reduced. Then calibrate the battery in time to active the protection circuit performance.
For early notebook batteries (Ni-MH Ni-MH or Ni-Cd Ni-Cd), really need to fully charge and discharge in order to maintain good battery capacity. But for the lithium battery is not necessary even it may damage the battery.
In fact the lithium batteries has a little memory effect. The lithium battery materials is very sensitive to the conditions as temperature, the use of frequency and so on. The battery will be aging after used for some period time (standby time reduced). The natural wear and tear is an important reason, and inadequate maintenance is another important reason.
A well-designed lithium batteries have a very good protection circuit to prevent excessive charge and discharge.As over-charging and discharging of the Sony VGP-BPS8 battery will be the rapid reduction activity. Under the protection of protection circuit, the user fully charge and discharge the battery several times, in fact, impossible to achieve had "full" level.
Sometimes WINDOWS show that battery capacity is 20% or more, you can use 30 minutes. But after used 10 minutes or less the machine suddenly automatically shut down. The reason is that the battery has been aging, the battery protection circuit can not monitors the battery real capacity. In the normal battery depletion, the protection circuit original parameters have been unable to properly reflect the actual situation of the battery
So power calibration procedure is to correct the benchmark protection circuit parameters to accurately reflect the actual capacity . This correction process will often take two or three complete charge and discharge. As previously mentioned, fully charge and discharge will reduce the battery activity. It is not frequently used, usually once a month.

When the laptop is unplugged does it l loose its charge even though it is not turned on? Also, can you overcharge and hurt the battery?


There is a gradual discharge from the laptop and the battery will go flat in a few weeks. The laptop is designed to charge the battery at an optimal rate. If you use the laptop on the mains supply with the battery allways, the battery will degrade. If you don't need the battery, charge it up and then remove it when you turn your laptop off. That way the chemical reaction is reduced and it will have a good shelf life. Charge it up twice a year if you are storing the battery.

My walkman wont turn on


Not sure if it's the same problem as mine! My battery was ran completly flat and then wouldn't turn on even after being plugged into the computer and hours of it juset sayin 'connecting'. I looked on Sony's website and found this -

Cause:
Battery is 100% discharged. Therefore, PC's USB with 5V/500mA set up has not enough power to start up the charging process because loading current is greater than the set up, therefore USB is disabled immediately due to sudden current load.
Remedy:
  1. Battery must not be discharged 100%
  2. If it happens then the supplied AC adaptor must be used firstly because it is providing 5V/800mA power. After a couple of minutes the unit can be connected to PC without problem then it can continue the charging during file transfer, etc.
I bought a usb adapter charger plugged it in and its back to normal!

How to maintain the durability of the battery


dont leave the computer pluged in all the time if the battery is being used. i would suggest if it will be plugged in for an extended period of time (mult. weeks) take out the battery. otherwise when allowing the battery to discharge let it discharge to below roughly 40% to avoid over charging or just charging, for lack of better terms, "to much".
