Re: Battery will not charge.
Computer companies like to sell you expensive batteries. You must always remove your battery while you are plugged in, or you will greatly reduce its lifetime of about 300 or so full charges. Also, to break a new battery in properly, charge it for at least 15 hours, then let it completely drain and recharge 3 times.
Now, however, it sounds like your computer's charging settings are messed up. Go to device manager, open batteries, open microsoft AC adapter, see if it says that it is working properly. perhaps it somehow got turned off, or the files are corrupted. if all ok, open the microsoft ACPI-compliant control method battery--if that is what is in your laptop--otherwise check whatever else you have. If nothing appears wrong, update or replace the drivers from Toshiba's website. let me know how it goes.

Dear power cord is use for charging your laptop battery so if you don't use power cord then you will be unable to charge your laptop battery. But this is truth that if your battery charge is okay then no need power cord but tell me bro how can you charge your laptop battery without power cord. This is totally funny. Yes one way, that is you can charge your battery by using dc adapter. But if you do it i am saying you that you just going to spoil your laptop and also battery.
POWER SUPPLY & BATTERY PROBLEM If thelaptop battery is more than 3 - 4 years old then the battery could be worn out.Rechargeable batteries have a finite number of charge and discharge cycles andwill lose their charge capacity over time, i.e. won't charge to 100% andgradually the charge reduces until the battery won't charge up at all. OR Thebattery shows a 100% charge but when the adapter is disconnected the batterydrops off to zero capacity in a very short time. If the battery drops to anunacceptable charge level then the battery needs to be replaced.Whenyou connect the power adapter into the laptop, does the power LED lightup? If not then -The battery adapter or the adapter's power lead or the laptop's powersocket could be faulty.Check power adapter's DCplug that connects into the laptop power socket with a multi-meter, the voltageshould be slightly higher than the voltage that is printed on the label on thebottom of the adapter. If the voltage is zero or way below the voltage that isprinted on the label then the power adapter is faulty and needs to be replaced.If the adapter is OK thenconnect it to the laptop and power it up, then look at the power/batterycharging LED light and wriggle the power plug in the laptop's powersocket. If the power/battery LED light flashes and in a certain position thisLED light stays firm, then the power socket is either faulty or it has a drysolder joint where it is connected to the motherboard.This can be repaired but itrequires the laptop to be completely dismantled to get at this power socket andrepair. If you cannot DIY then I suggest you get a quote first.
Laptops that I have worked on do not need the laptop to be switched on to charge the battery. There maybe a LED indicator on the laptop to indicate that the battery is charging when the power adapter is connected.
there are a couple of ways to check, if your battery has a test light indicator you can press it will tell you about how much power is by how many lights light up, if it doesn't have one, you may have to trust the windows power indicator. if you go to control panel you can go to your power options and one of the tabs should have a power reading. Also some bios versions have a battery section which tells you how much battery life there is. until they make a charger that automatically shuts off when the battery is charged this is the only way to tell
Most laptops will work without a battery as the house current is converted to usable voltage for the lap top as well as to charge the battery.
The battery is not charging because the voltage level has fallen below a safe level to recharge. Li-ion batteries have a safety feature built into them. A small chip is wired into the battery to tell the power supplly on the lap top that it is OK to charge the battery. If Li-ion batteries internal charge fall below a certain level, that chip signals the charger not to try to charge the battery as it would demand a higher charge rate and raise the battery temperature and cause a fire, so it in effect says don't do it. If the battery charge falls further, then that chip locks out the battery and shuts down your computer.
One thing you can try, put the battery in your freezer for about an hour, and then put it back in your machine and see if it will come back to life. Do not let the battery freeze, just an hour will do. You may want to try this a couple of times, but your batter is at it's life end.
Hi,the reason why your laptop is telling you to replace Battery is,you have killed your battery without knowing by Charging it always,since you have constant power supply,you should at least after getting a new Battery,discharge it four to five times a week longer life of battery,by these i mean,unplug cord from mains let power drain to 5% or 10% before charging again while working and if fully charged and you are not making use of it disconnect and if you want to make use of it use battery instead do not connect immediately to mains until power drains from battery.Just like your mobile phone,you only charge it when need be(ie. when Battery is Low).
I just had the same problem. My battery had discharged to less than zero and would not start even though the power plug was in. I tried everything... but what fixed it for me was to remove the power plug, remove the battery, plug in the power cord and start the machine. Once the machine was already booted, I put the battery in and it started charging. Dont know if that will fix your problem, but it fixed mine.
Most Dell batteries have an LED indicator that allows users to see how much run time and how much overall battery life are available at the touch of a button.
To check battery charge, press the button and the number of lights that appear will tell you charge status. If all lights appear, you have a fully charged battery. Each light that appears accounts for approximately 20% charge.
To check the battery health, press and hold the status button on the battery charge gauge for at least 3 seconds. If no lights appear, the battery is in good condition and approximately more than 80 percent of its original charge capacity remains. Each light represents incremental degradation. If five lights appear, approximately less than 60 percent of the charge capacity remains, and you should consider replacing the battery
if the ac adapter will power the laptop without the battery installed its fine. if the cord is fine and your battery is fine its a mother board issue and it will most likely have to be replaced
