You laptop should come with a care and instruction manual. When it comes to actually operating it, it won't be much different than using the computer you are on right now. Just bear in mind that you need to keep the battery charged.

not necessarily its used for avoiding DAMN BURN INS....for crt monitors...its more effiecient if you use POWER SAVING OPTIONS....

I believe most laptops either have a standby or hibernate feature where after a certain time the laptop shuts off automatically. i don't think it's bad to leave it on all night, but if you're laptop has this feature, there's no need to worry about it. it'll turn off by itself.

I am afraid your battery is dead\n\nIf you can run it on AC power but on battery, it is dead.\n\notherwise check battery connectors

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.

Yes, of course.\nLaptops are made to be charged, and they charge fastest when shut down as they are not relying on power. I have to contradict what someone has said; I leave my laptop charging overnight all the time, and it has not done any damage to the battery.\nI hope what you do, is if you are using the laptop during the day you do not have it running on AC power, I'm pretty sure it is better to be running on battery.

Short answer: no.\nLonger, more complete answer: it depends.\n\nWhile on, the UPS uses a small amount of electricity (which costs a small amount of money), produces a small amount of heat (which makes air-conditioning run a tiny bit more, which costs money), and provides a small charge to the battery in the UPS which keeps it in tip-top condition (maximum battery life).\n\nWhile off, the UPS uses no power and produces no heat, but the internal battery "self-discharges" at a slow rate.  This means that you won't have 100% capacity when you turn it (and the computer) on, and the repeated small self-discharge & re-charge cycles will slightly shorten the life of the internal battery. If there are long periods when the computer (& UPS) would be off (like weeks), then this self-discharge could be significant.\n\nSo, if electricity is hideously expensive, or air-conditioning is costly or unavailable, then turning off the UPS might make sense.\n\nIf you've got no money to replace the UPS and the battery has to last as long as possible, leaving the UPS on makes sense.

Why don't you just use the setting within windows to detect power.... if the laptop is running on batteries then have the computer turn off or go into hibernate.

This does nto seem to make much sense unless the battery is so old that even at a full charge it does not have enough battery power to run all of the necessary parts of your laptop. You can try this. go into: START, CONTROL PANEL, POWER OPTIONS, under POWER SCHEMES you can pick PORTABLE LAPTOP, then you can check the options below of how you want the laptop to run while plugged in to AC and how to run plugged in to BATTERY POWER.  Hope this helps...\n\nIf neither of these situations fixes your issues, then you may need to go into your SYSTEM Properties and check out to make sure all your devices are performing okay..

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.

Even though the battery says its charged it may be bad. Do you know someone with the same laptop, so you can borrow thier batttery to test it.

Yes it is perfectly safe, The device will only draw the current it requires. So as long as you are providing at least 300mA the device will operate without being damaged.

add more RAM. that or you can open it up and mess with the jumpers or switches. Doing that will cause the processor to become hotter and it may overheat, ruining you notebook.

Turn it off first if you care for your laptop..

You should be ok if you have it on a hard surface like a desk or table. \n\nIf you have it on the floor, or couch, or table with tablecloth, it may overheat due to the fan being blocked by the fabric.  Overheating is bad as it can kill the motherboard and/or drive and you would have an expensive paperweight.\n\nLeaving a computer on is supposed to be good for it since booting from the off state over and over adds wear and tear to the system.  I have a PC that I power off every night, and a work laptop that gets shut down once or twice a day, both work fine.  I haven't rebooted my mac in over a month and it too works fine.
