composed of either nickel cadmium, nickel metal hyrdride of lithium ion technologies. These types of computer laptop battery technologies, as so many elements of the high-tech world, are better known by their short abbreviations:\n\nNickel cadmium is known as NiCad\nNickel metal hydride is known as NiMH\nLithium ion is known as Li-Ion.\n\nThere are some differences between two nickel-based laptop computer battery technologies. (The NiMH version is the newer of the two versions of computer laptop battery units.) The NiMH computer laptop battery offers higher energy density than does the NiCad version. Generally speaking, the NiMH computer laptop battery delivers approximately 100% more capacity that its nickel-based counterpart.\n\nThe NiMH computer laptop battery also does not suffer from what is known in the industry as "memory effect." This is the effect in which unless a battery is drained completely before each recharging, the computer laptop battery will end up ultimately never fully recharging. The final result of the memory effect is a serious limitation of the expected lifespan of the subject computer laptop battery.\n\nOn an unrelated note, because the NiMH computer laptop battery does not contain the same heavy metals as theNiCad technology, it is more environmentally friendly. A significant problem in recent years has been the increase in heavy metals and products like some computer laptop battery units containing heavy metals that have found their ways into municipal landfills causing serious environmental damage.

Turn your laptop off and turn it over.  Somewhere on the bottom, there should be a compartment that contains a battery that is used to keep time when the computer is off.  Open the compartment, and take the battery out for at least 2 minutes, and then replace it.   Your computer should unlock.

take the battery off of the motherboard and leave it off overnight, or use the password jumper on the motherboard if it has one.

doesn't matter what kind of car u have. matters what kind of battery your car has. i would guess that if the cars battery was new you could use your laptop for about an hour and  a half before you need to start your car. maybe even 2hrs. also, diehard car batterys from sears are about the best you can buy if u want to upgrade. would probably double the times i estimated

i would go on eBay and see other notebooks that are near the hardware profile that you have. that will give you a good basis.

check first if u r using the right converter . if it is the right one and u used to use it until a problem exist then check ur laptop it has a burnd diode or transistor

my computer doing the same thing i called a computer store and they said that my battery has gone bad and i need to replace it. go to tigerdirect.com and you can get one pretty cheap

It could be a ton of things.  Try these first:\n\nPop the battery out and plug in directly to the wall.  If it powers on, you have battery problems.  If not, jiggle the power cord in the back of the computer and keep pressing the power button.  If no luck, try doing the same while jiggling the cord to the wall or to the power brick.  You either have a bad motherboard or a bad power adapter.  Try another adapter if you can.  Is it on warranty? \n\nI just sent my laptop out yesterday with exactly the same problem...and it's either a fried motherboard or bad power adapter.

Consult your laptops manufacturor's website, they should be able to tell you!

Sorry to hear about the misfortune. You gotta go to the manufacturer website if your unsure on how to install the product. When installing memory in a portable, the manufacturer will usually instruct you to remove the battery and any peripherals attached to the computer, and disconnect the ac power adapter to prevent damage to the pc and the memory.

You can actually conduct a simple test on your battery. Leave the laptop on for about half and hour and after charging fully. See if the battery drains fast. If yes then you have to change your battery. Is yours a new note-book or seasoned one. If new then you can actually contact your vendor and inform him and see what he can do for you.

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.

Plugged in or not plugged in?\n\nIf it's not plugged in, there should be a battery meter that'll let you know how much battery power you have left. Some computers (like Macs and Linux machines) will translate that into hours and minutes for you, some (like the few Windows laptops I've had) won't.\n\nIf you're asking how long you can run it when it's plugged in, it's really up to you. If you can keep the ventillation going (laptop is a misnomer- there's little viable ventillation going on when the computer's on your lap) and the air temperature is not too hot, you can theoretically run it as long as you need to. I think we've run our laptops 10-12 hours at a stretch sometimes when something's uploading, downloading, or compiling.

Nothing you should be worried about. If it does, it will be like 1 second less, but the fact is.. if you have more RAM things will get done faster so you can do more with less time. RAM will not hurt the battery life, it will only help it.\n\nhristo_y are you a moron? I was saying, the computer WILL consume more energy but you will not notice the difference. The computer battery may last 1 second less from the extra power it consumes. Try answering the question and not saying something ignorant.

In laptops of any age the charger is just providing mains power after the battery is charged. Worry not.

For the battery life, I heard that it's better to take out the battery when you're using the AC adapter, unless you specifically want to charge it.\nOtherwise, the battery will charge, then discharge a little, then charge again, etc. and this may wear it out.\nFor the same reason, use the AC adapter whenever possible.\n\nBesides that, just be careful not to hit/drop/spill something on the notebook.\n\nAbout the first answer: "Frequent full discharges should be avoided when possible" and "Avoid frequent full discharges because this puts additional strain on the battery" (see the source below)

I don't hink you can go wrong with either a Dell Latitude or IBM Thinkpad.  They are both quality machines and usually competitively priced.  Nowadays, long battery life is about 5 hours, but if you buy a model with 3 hours of battery life, you can always buy an extra battery, dim your screen, turn off the radios (Wifi and bluetooth) and you'll be up and running for a long time.
