laptop battery not charging

July 1, 2010 at 22:45:50
Specs: Windows XP
My laptop is 3 y.o.
Last night, while on AC power, i got a message saying the battery needed to be charged. It kept saying that for like 20 minutes, then the screen went black (power saving feature) while the laptop was still on, but i couldn't turn it back on, so i turned the laptop off by pressing the power button. When i tried to turn it back on it didn't; i left it on AC power over night. Still doesn't turn on.
Is it the charger? the battery? or even worse, the laptop?
Please help! Thanks.

i believe when charger is connected automatic battery start charging.
In your case "while on AC power, i got a message saying the battery needed to be charged" all this time your are using battery power that means no power coming from charger. Did u try to remove the battery and connect charger?

I tend to always have my laptop plugged in with the charger, so i haven't used the battery alone much.
I did take the battery out, but the laptop isn't turning on. I've also tried cleaning the contacts for the battery and putting it back on. Whatever i do, the laptop seems dead, doesn't respond to anything.

may be the charger is bad or the wire (charger to pc) is bad or the jack is loose or powerboard is bad. Take it to the shop were they can check the charger and the system.

Laptop no video (or video problems), and battery, AC adapter, power jack T shooting.

If there is nothing wrong with your AC adapter's connection and the jack in the laptop.......

Laptop main batteries usually work as they should for a year or so, then they begin to rapidly deteriorate. From what I've seen, by two years they cannot be charged to anywhere near their full capacity, and it gets worse after that.
They often develop internal shorts when they are older. If the battery gets HOT rather than just warm after you have attempted to charge it for at least a half hour, it's definitely internally shorted and you must replace it. Internally shorted batteries getting too hot have been known to cause the laptop to catch on fire.

there is no way for me to check if the battery gets too hot as my laptop is not turning on.
but i've had it for 3 years, so maybe it's time to change it.
Thanks for all the info :)

Read the info at the link I provided.

If there is nothing wrong with your AC adapter, the AC adapter's connection and the jack's connection in the laptop.....

The led you probably have that indicates the battery is being charged on the laptop when the AC adapter is connected to the laptop should light up even when the laptop is off, at least briefly when you first plug in the AC adapter, if not all the time.
If it does light up, the battery may get HOT after a half hour or so, if the led stays on continuously .
If it doesn't light up, you have some other problem, including possibly sometimes the main battery may develop an open circuit internally.

If you're not sure whether you have an led for that, see your Owner's or User's manual for the model.

By the way, if you have dropped the laptop, or have spilled liquid on it, since it last worked properly, those reasons are the most frequent reasons a laptop gets damaged such that it can no longer work properly.

I've never dropped it or spilled liquids on it.
Just tried again to turn it on, but it doesn't respond. I've kept it plugged in with the charger, removed the battery and put it back on, the charge led lighted up just for a second, and then went off. When i press the power button, that led blinks a few times then goes off. But the laptop doesn't turn on. I haven't been able to turn it back on since thursday 2 days.

If nothing were wrong with the AC adapter's cord or plug at the laptop end or the jack in the laptop and the battery , the charging led will only light up briefly if the battery is already fully charged, when you unplug the AC adapter then plug it back in, or unplug the battery, plug it back in when the AC adapter is connected (not recommended when the AC adapter is plugged in).

Have you tried wiggling the AC adapter's cord near the plug into the laptop?

If there is something major wrong with the battery such that it can no longer retain at least a minimal charge, your recent laptop probably cannot run on the AC adapter alone or when both it and the main battery are installed.

You could try replacing the battery. That may restore your laptop to working again just fine, but that will, of course, cost you some money for the battery.
You don't necessarily have to get the brand name's battery - any battery that is compatible with your laptop will work, and there are many no-name or lesser name brand batteries that are much cheaper. As long as the warranty is a year, that's the same warranty as the brand name's battery. They all come from the same places these days - usually China.
If you live in a reasonably large enough location, local places probably have one in stock, but it may cost you more than one you can get on the web and have to wait for.
When you install the new battery you need to plug in the AC adapter to charge it with the laptop off for a while. Then the laptop should start up fine.

Or you could take it to a laptop repair place and they could analyze your problem for a small fee - they would probably have a compatible battery and an AC adapter that would work with your model in stock, and could try that.

I'll be calling a few places tomorrow to find out fees, and you are correct, it will be cheaper to buy the battery or charger (or both) from the web...but until i don't know what's wrong i won't buy anything....don't really feel like wasting money; i'm just really hoping it's not the laptop that's faulty.
Thanks heaps for all your help :)
