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.

1. no a 7 amps charger cannot harm u'r notebook, neither can a 700 amps charger, provided the voltage rating is correct & it's a smps\n2. i will never recommend a charger from a different supplier than notebook manufacturer, reason being a. the battery charging circuit is a bit tricky, an auto cut-off switch mechanism for supervision / regulation charge: boost / trickle / off states b. the mating pin connecting notebook can make a loose connection, causing localised heating / sparking\n> if at all u buy different, only supplier i know of is targus\nhttp://www.targus.com/us/powerstore.asp\nfill in relevant details & after a few steps, offer comes up

Hi! It's made to extend your battery time. Just get into your wireless card properties and turn off power saving option. ;) gl

I am pretty sure that as long as the main battery is charged you don't need the backup battery.  It's there just in case your main battery should fail.

if you got it used. then the batt is dead. if you got it new ans under 2 years. then i would also have you systemboard checked out. some dells systemboard for laptop came from compal systems. that did make systemboard that where bad contacts that charge the batt.

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.

(If it's laptop) you just have to charge it. If that doesn't work, replace the charger. If that doesn't work too, replace the battery. If nothing works, buy a new computer.

LOL that battery does suck doesn't it??? I own one also but as long as you are happy with the laptop then go http://www.toshibadirect.com/td/b2c/adet.to?poid=294716&seg=HHO&coid=-26627&rcid=-26363&ccid=1291043\nThis is a direct replacement from Toshiba that has almost twice the capacity.

Why did you take the battery somewhere to be charged if the laptop is not on but you have it plugged in you are charging the battery.  Check the metal connectors on the battery for corrosion, dirt, etc....  When you hit the power button does it make any noise(beep, humming?)?

This is what Dell says their current warranty is for their notebook computers.  I'm not sure if they changed it over the last seven months?\n\n"Portable computer batteries and AC adapters carry the lesser of either a 1-year limited warranty or the length of the limited warranty for the Dell computer with which the battery or AC adapter, as applicable, is shipped."\n\nIf your laptop had a one year warranty, then you should be covered.  Go back and look at the paperwork Dell send you when you purchased the laptop.

Its better u plugged ur battery out...!\nEvery battery has LifeTimer..! when u left it plugged in, it will decrease its LifeCycle. \nTo ensure lasting ur battery, from time to time, try to charge it nearly 8hrs without turning on ur LapTop.!\nenjoy it ;)

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.

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.

if you want to charge, but it can also be plugged when not using. most of the rechargeable batteries today use NiCd or NiMH, so it can automatic stop charging and it can charge the battery even it is half empty. not like batteries before that you must discharge it first before charging it.

Yes.... US current is different from what is used in other parts of the world my Friend... I would advise you, believe it or not, to go to WalMart and get a "universal converter" set... This contains several different adapaters that will allow you to use not only your laptop, but other electrical appliances as well... Makes it a lot easier... Been there, done that!\nTake care...\nThe Duck

well, i think it is... but just in case, while its charging, move the click wheel around until the screen comes up. then at the upper right hand corner where it tells u how much battery u have left, there should be a picture of a lightning bolt which means its charging. if its a picture of a plug, it means that its done charging.
