The battery wont charge for my lt2802u


POWER SUPPLY & BATTERY PROBLEM
If the laptop 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 and will lose their charge capacity over time, i.e. won't charge to 100% and gradually the charge reduces until the battery won't charge up at all. OR The battery shows a 100% charge but when the adapter is disconnected the battery drops off to zero capacity in a very short time. If the battery drops to an unacceptable charge level then the battery needs to be replaced. Rechargeable batteries will fail if stored in a discharged state for long periods. When you connect the power adapter into the laptop, does the power LED light up? If not then - The battery adapter or the adapter's power lead or the laptop's power socket could be faulty. Check power adapter's DC plug that connects into the laptop power socket with a multi-meter, the voltage should be slightly higher than the voltage that is printed on the label on the bottom of the adapter. If the voltage is zero or way below the voltage that is printed on the label then the power adapter is faulty and needs to be replaced. If the adapter is OK then connect it to the laptop and power it up, then look at the power/battery charging LED light and wriggle the power plug in the laptop's power socket. If the power/battery LED light flashes and in a certain position this LED light stays firm, then the power socket is either faulty or it has a dry solder joint where it is connected to the motherboard. This can be repaired but it requires the laptop to be completely dismantled to get at this power socket and repair. If you cannot DIY then I suggest you get a quote first.

Tip

Looking for the longest battery life laptop ?


We’ve yet to see a Windows laptop with battery life longer than 5~7 hours, unless we add an extended battery to the system. But when hpand dell launched its new series of laptops last week, one big push wasfor longer battery life.

When you purchase your notebook, charge the battery to 100 percent,discharge it completely, and then fully charge it to 100 percent againto help the battery remember exactly how much electrical charge it canhold. From then on, you’ll never need to completely discharge the laptop battery again, but always make sure when charging it that you let it reach 100 percent. DeHoop told us to “remember to plug in the laptop AC adapter(or dock/port replicator) whenever you get a chance. Most notebookswill recharge quickly.” Salinas had another tip for your batteries:“Keep them cool. Exposure to high temperatures can be a battery’s worstenemy,” he said

Hope the list can give you some help when you purchase a laptop or battery:

Toughbook will not start, we have it plugged into the wall and when we switch it on the battery light turns red and nothing else happens? Thanks, Brad M.


> battery light turns RED

For Panasonic computers, that indicates that the battery is almost completely discharged (it's YELLOW while charging, and GREEN while fully-charged).

So, my guess is that your AC adapter has failed,
and that your battery needs recharging.

Or, the socket where the AC adapter connects into your computer is damaged, such that no power from the AC adapter is reaching the computer.

Take a "MultiMeter" and check the voltage & amperage output-level from your AC charger. If "zero", go onto eBay and search on the part-number, to find a compatible replacement part.

Dv6000 not charging


If your charger is functioning good and you have checked for proper voltage at the tip. should be 18.5 to 19 volts. Then most likely your battery has dead cells and will no longer accept a charge. These laptop Lithium Ion batteries do not do good with being run all the way down and then recharged back up. it destroys them, they are only good for so many recharge cycles before they fail. Laptops should be left charging all the time when near an outlet and only should be used on battery when an outlet is not available. Change out your battery and everything should be back to normal. Ebay has them for around 36.00 US dollars.

Labtop battery goes dead very fast.


Depending on the age of the battery this may or may not be a problem. Most rechargeable batteries reach a point were they will no longer hold a charge. I've reached that point on my 7 year old HP laptop and will be getting a new vatterty any day now. I'm assuming your laptop functions if you use the power adapter and have it plugged in. If not your problem is probably not the battery but the laptops power management circuits. Replacing the battery is a pretty simple DIY job. All you'll need is a screw drive and some free time.

how old is the laptop/battery? rechargable batteries sometime with age; I'm told, over time lose their ability to hold a charge. As far as model number number, usually at the bottom side on the sticker you can find all information you need.

Compaq Presario needed a new battery was installed labtop will not charge up!


When you install a new battery and remove a battery always make sure the laptop is completely shut off and have the power cord removed so that you avoid any possible power surge.

Batteries generally don't last much longer than a year and I have found removing the power cord or battery when it is off to be a good practice.

Before you charge a battery make sure it is run most all the way down. Recharging a battery when it is not run down can give it a memory and you may only be able to charge it up to the point you started charging it.

Anyway, if the computer won't charge a new battery then you could have a bad motherboard. To be sure try another battery.
