Should you leave it plugged in as much as possible, or only when the battery wears out?  My husband seems to think it will get ruined if I leave it plugged in all the 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".

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

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.

you can leave it any wear it will break down quickly, like a leaf off of a tree. can you just give me the points no one else is going to answer

I recently read about new power strips that cut even standby power to equipment that are plugged into them. For example, your computer and printer still draw a current even if shut off. this tricle can add up over the course of a year. These power strips cut off that tricle until the moment the unit is roused from standby.\n\nThis was in a pretty good article in this month's Kiplinger's Personal Finance magazine.

BATTERY AND CRAP???? lolz...wat exactly were u tryin to say!??! guy said he uses AC power not BATTERY..'nd i....errrrrm.....ammm..i dunno wat to say...guys help him out.... yo man..tc...!!

easy,you got to let the charge leak out.when your a car you can take your shoes off and stuff like that but there really is nothing to worry about just because the voltage can range from 10 000 to 20 000 volts it does not necessarily mean its going to harm you, it has a very low current(which does harm in high doses.

You should remove the batteries because even if they are not used, the chemicals in the battery can eat through the housing and damage the device.\n\nAlso, the chemicals in the batteries have a "shelf-life" where they will react slowly even if there is no electrical discharge.

No need to turn it off DUH!!!  LOL!  Everyone has "brain farts" :)

do you look after the battery. charge it up full then use it till it is right flat every now and again. don't use it when laptop is plugged into mains as this puts a constant charge through it. if you do get a new battery then don't be tempted to use it a.s.a.p . let it charge fully!! or else the battery(depending on type) will remember the stage it was charged to and will never charge past that point(the same thing happens to people with their brand new mobiles who can't wait to use them)

The UPS has an internal battery that is disconnected for shipping.  Have you connected the battery inside?  Did you get the polarity right? If the UPS is plugged into the wall and turned on, it should power any connected devices while it charges the battery, assuming that the wall plug is live.  If this is a used UPS that you inherited, then the battery may need replacing.  The battery has a finite cycle life.  Check to see if the circuit breaker or fuse is reset and good.

no u can use the ac power supply it wont hurt it cause that's how u recharge the battery so don't worry about it just use it like that

Could be a dead battery. The lifetime of lithium ion batteries varies with temperature, number of recharge/discharge cycles and percent of discharge and percent of recharge. Complete, 100% recharges actually shorten the lifetime, but, complete discharges are worse. Partial discharges and partial recharges can lengthen the usable life. The lower the storage temperature, the better, but, DO NOT freeze. High heat, such as in a vehicle or storage building in summer drastically shortens the expected lifetime. A lithium ion battery's normal lifetime is about 3, maybe 4 yrs. Best longtime storage is at 40ish degrees F with about 40% charge. ( just the battery, not the device )

Contact dell and tell them you want a new battery. dont leave it any longer, cos after the 1st year they dont want to know about the battery.\n\nTrust me your battery is fubar, its happened to me several times.

If you use it alot, you might try cleaning the player. You can get a cleaner at most electronics stores.

A lot of airlines have blocked off those little plugs - they don't want people plugging stuff in due to fire hazard.  You should call the airline, or see about spare batteries.  Personally, I don't think your PSP would be too much of a hazard, but if something goes wrong, help is a long way away...

Although it is quite possible that nothing noticeable will happen (I have done this hundreds of times without major consequences), you should try to avoid it at all cost. There are three main reasons for this:\n\n1. You will probably lose any unsaved data.\n\n2. It could damage your computer and/or shorten its life.\n\n3. It could cause some files (that HAVE been saved) to be permanently deleted and/or corrupted. Although this is fairly rare, it has happened to me before--and the possible risk is worth serious consideration. All files are at risk; including system files, program files, and all personal files.\n\nSo I suggest that you fix this problem. There are a few different ways you can do this. Your best option is to buy a battery backup system--it should cost you about $25-$45--it will protect your computer from unexpected blackouts as well as it being accidentally unplugged. You could try getting a new surge protector (I assume that is what you mean by an "extention thingy that has a saftey on it")--they are usually about $5, but you can sometimes find them for free with a rebate. However, if you aren't going to get a battery backup, instead of replacing a functional surge protector, I suggest you simply bend the electrical contacts (prongs) outward slightly; this will improve the electrical connection and hold the plug in place.
