Laptop battery--is it a goner?
918618
1.  Disconnect the battery physically from the laptop - let it discharge for a few minutes.\n 2.  Put the battery back into the laptop.\n 3.  Boot up laptop and charge battery.\n 4.  Shut down laptop and unplug adapter from wall and laptop.\n 5.  Boot up laptop\nIf the battery does not maintain a charge at this point, it's probably a goner and needs replaced if you would like to do work independently of a power adapter.

Best value, 100% of the time on notebooks, is Toshiba.  I've recommended them to a few people, and every one of them that bought one has been completely satisfied with it.  By the way, people usually don't sell a laptop (they're so expensive in the first place) until there's something wrong with it.  I would either buy a new, but not top of the line model, or used if I can test it out first.

First look at the adaptor and get the output rating of the adaptor. It will also show a pictogram of the adaptor plug this shows what part is negative and positive at the laptop end). Look for a new adaptor that has the same rating (or extremely close) and the same pictogram of the plug.\n\nThe ones for the laptop may be quite expensive.\n\nAlso get the battery looked at, it may be faulty.

Laptops come with batteries.  If your laptop doesn't run when you remove your AC adapter one of several things could be happening.  You could have a bad battery, which is the first thing to check.  If your laptop is under warranty I always suggest contacting your vendor for support.  While not usually a fix, cycling the battery does sometimes help (especially with older batteries - it's not so much an issue anymore).\n\nIf your laptop isn't under warranty you really only have a few options.\n\n1.  you can take it in to a professional and have them figure out what's wrong.\n\n2.  you can try basic troubleshooting steps and see if you can figure out what's wrong.\n\nGenerally speaking laptops that don't run on their own battery power but on AC power have bad batteries.  The first thing I would do, is hop on a auction site (ebay/yahoo/wherever) and try to buy a good used working laptop battery.  Replace that battery, give it a few hours to charge and see if that fixes your problem.  If it doesn't - then you probably have a issue internally with your charging system.  Which at your level means taking it somewhere to be serviced.\n\nDoes your laptop run at all without the power cord?  Even a short time would suggest that the battery just needs replaced.

3 weeks is not a long time, but it is too long for charging ;) It is recommended charge battery 2/3 of it's capacity and take it out of laptop - in case you leave laptop for 1 month or more.

You'll need to take the laptop apart and find the CMOS battery. It looks like a watch battery attached to your laptops motherboard. Take it out for 45 seconds, then put it back in. This sets your BIOS back to defaults and also removes your password. I wouldn't suggest doing this if you've never been inside a laptop.

1.\nPower down all nonessential functions. Switch it off if you're not using it. Many business travelers already know that you don't want to take the DVD player for a spin on the plane, and that every time you hit "save" it can set the hard-drive whirring, which devours even more power. "But users often also forget to turn off their wireless card when they are no longer using it but are still using their computer," notes Mike Fuller, executive vice president of PC Laptops, a Sandy, Utah, laptop manufacturer. "When the wireless card is on, it still continually searches for networks." In Windows XP, click on "Power Options" in your control panel. It allows you to reduce the power consumption of any number of your computer devices or of your entire system.\n \n2.\nStay out of extreme temperatures. The technology that powers you battery isn't terribly complicated. But it's important to understand a little bit about the chemistry behind batteries, and how that can affect your work. Specifically, temperatures can affect the performance of your battery. It's best to use (and especially charge) your batteries at room temperatures. Extreme conditions can drain your battery quickly. Also, avoid partial charges and use the battery until it is dead. Battery experts liken partial charges — and discharges — to eating a cup of lard every day. It significantly shortens your battery's life. Considering that a lithium-ion battery can explode if it's improperly used, it could also shorten your life.\n \n3.\nLet your laptop do the saving. Not every computing device handles a power source in the same way. Some of the more sophisticated laptops, which are designed with business travelers in mind, are misers when it comes to using power. And that's a good thing — if you can remember to take advantage of it. "Most users make the mistake of simply not choosing to use a product's built-in ability to conserve battery life," says Dan Coffman, a senior product manager for PC manufacturer ViewSonic. How do you harness your PC's built-in ability to save? Consult your user manual. Often, calibrating your laptop is as easy as double-clicking on the battery icon in the toolbar.\n \n4.\nAlways, always carry a spare device that uses batteries. How obvious is that? Well, if you're trying to keep under the onerous new airline weight-limits, it isn't. But as Rick Thompson, director of engineering at Valence Technology in Austin, Texas, observes, "the availability of 'free' power outside of your hotel room is not predictable." That's a nice way of saying it. In fact, I sometimes think airport terminals, car-rental facilities and hotels try to hide the power outlets from us to keep us from accessing their free power. Thompson recommends a system that can simultaneously charge a second portable device such as a cell phone or PDA, allowing you to multitask your battery operations.

Even if you have your laptop powered down, the battery is still providing energy to the laptop to be able to turn itself back on, not to mention that the BIOS has to have constant energy.  This is why you will notice a slight drain, it's nothing serious, just necessary for the laptop to continue running correctly.  To put it simply, a computer needs constant power to be able to keep time and settings in BIOS, and to be able to initiate the startup sequence.  Hopes that sheds some light, my $40,000 education just answered your question.

take the battery out for a few minutes then replace.\n\n\nthe mother board battery is what i was talking about!!!!!!! had to perform that operation myself and it works wonderfully. and not all laptop main board batteries are on the motherboard, mine was located in a small compartment underneith the laptop.\n\nUPDATE: you could just also bash the thing repeatedly on the concrete untill it is just a bunch of tiny bits, that will get rid of the password too.

There are two schools of thought but my tech support from Gateway said turn it off if you are gone 2 hours or more. I don't do that. I set it to hibernate at 2 hours. (In Control Panel, Power Options). However, as to lithium batteries they can 't  be ruined by overcharging. I leave my computer plugged in several days at a time.

Wow, there seems to be some differences of opinion on this one. Well perhaps I can help clear up some of the mystery.  I have actually done quite a bit of research on this topic.\n\nThere is this thing called "battery memory".  It doesn't actually have anything to do with memory, what it refers to is the battery's ability to hold a charge.  If a battery is not discharged all the way before it is recharged it starts to develop a "memory" of the amount of discharge. It doesn't happen right away but eventually it gets to the point where the battery will no longer charge to the full capacity it used to have.\nDifferent battery types are effected by this different amounts.  Alkaline batteries are severely effected by it. Lithium Ion batteries (the kind in a laptop) are not nearly as effected by it but are still a little effected.\nThere is something else to consider however.  All batteries, especially lithium Ions and most especially cheap lithium Ions loose there charge over time, even when they are just sitting being unused.  This means that every few hours or even every few minutes depending on your battery and laptop, the battery charger kicks on to get the battery back to 100%.  This rapid charging and discharging will quickly hurt the batteries life.\nOf course this is only one of many things that can and will effect the life of your battery.  The manual to your laptop should have care instructions for it.  Usually it recommends running on the battery and draining it completely dead then doing a full recharge around once a month.  This will help stop "battery memory".

Will it stay running in safe mode?? or does it still turn off? if it stays running in safe mode, it is not the thermal overload switch...\nIs it a lap top? if so remove the batt and leave it pluged in. will it stay on? might be the Batt going bad... post back!

A friend has one and just got it back from service. The cooling motor was cutting out and shutting down the computer. Also the battery was replaced due to concerns from Sony.

Open up the Machine....Just Check the Motherboard...you will Surely Find the Battery.......

i depends on what you are going to use your laptop for if you are having it at a desk all day with power plugs close a low cell battery will be fine. but if you are going to travel lots there are advantages getting to higher celled battery and yes higher celled batteries do heat up more depends a bit on the brand

It depends, If you are constantly in one place using your laptop, then there is no charge or discharge done. Keeping it always plugged in is one way, but to prolong it you should use a battery optimizer. Use a search engine to find "laptop battery optimizer" this will discharge the laptop to 0% power and then fully charge it very slow, thus allowing the battery to caliberate. Message me if you have a question.

You can try this:\n\nhttp://www.batterystandard.com/product.asp?ItemID=13314\n\nI just checked on eBay and they don't have any listed right now, but that's always a good place to look as well.  You may want to do a search by the make and model of the laptop too - that might give you other batteries by different manufacturers.
