How come my laptop battery dies out a lot and take forever to charge up?
I just bought new battery and it's my 3rd time buying my ac adapter. my ac adapter always get extremly hot and when my laptop battery is going low it take about 2 hours to charge it back up to 100%. Usually it takes less thant 40 minute to charge it back to full charge. Anyone knows what's wonrg. Sometimes my air vent on the bottom of my laptop get hot too even though I do not cover it up too.
Laptop batteries can be overpriced and not always get you the battery life you need. Hot ac adapters are fairly common computers and laptops. Even if it's new, you may have gotten a bad battery. Refurbished batteries usually have a 30-day warranty and cost a small fraction of the price as new. You might search for a refurb battery for your laptop just to confirm that it is the battery that's the problem and not the laptop.

How to get them to actually do something about laptop ac adapter?
I have a Toshiba laptop who's AC adapter keeps going bad. I was curious if anyone had suggestions on what could be causing it to go bad so often. It's currently under warranty at Best Buy, so anyone that knows how things work there and how to get them to actually do something about this, advice would be greatly appreciated.
To give a better idea of how often it's gone bad, and how long they've lasted, here are some dates of when I had them replaced:
12/2003 (bought laptop)
11/2004 - first replacement
3/2005 - second replacement
3/2006 - third replacement
7/29/2006 - fourth replacement received
8/10/2006 - fourth replacement starts beeping, fifth replacement received
8/13/2006 - fifth replacement starts beeping
The last one they gave me only lasted 3 days. I waited on bringing it back for service until now, as I needed the laptop for school. I finally brought it in for service on 8/15. About a week ago, they told me they were finished and I could pick it up. When I went in to pick it up, I was told they simply replaced the AC Adapter again. I refused to take the laptop back, and asked them to send it in for service again, this time to figure out what's causing the Laptop AC Adapters to die so often. I called them back today, and was told that their tests couldn't pick up anything wrong with the laptop, and so everything must be normal, and that possibly I was plugging it into a bad outlet. I do not think that is the case, though, as I've lived in at least 3 different places for an extended period of time over the past 2.5 years, and the same problem happened at all 3 places, none of which gave trouble to any other appliances or computers. On top of that, it was always plugged into a surge protector.
I'm supposed to pick up the laptop later today, but still nothing has been done to correct whatever is causing the adapters to die. Any suggestions on what could be causing it? Or how to get Best Buy to actually fix it.my warranty expires in a couple months, so I'd like to get this taken care of before then.
How much power your laptop is using normally
A slight buzzing sound that varies with current draw (how much power your computer is using) is normal. Also heat is a natural byproduct of its operation. They can even get almost too hot to touch when under high loads.It shouldn't be anything to worry about.
I personally leave my laptop battery in my laptop at all times, as it acts as an uninterruptible power supply if the power goes out for any reason. It has saved me a few times.Taking out your battery will extend its useful life. But lithium batteries degrade over time anyway, and it will not save your work in the event of a power outage – so in my opinion, it's not worth taking it out.
It's the heat that speeds up the degradation of your battery. Once the battery reaches full charge, it completely stops charging (for all intents and purposes). It it still not worth taking the battery out for the reason I mentioned above.
For storage, keep it at 40% (check it once in a while to make sure it hasn't dropped, do not ever let it completely discharge it may degrade 20% or more in an instant)
The first Dell notebook AC Adatper I had with this laptop has some kind of degraded wire, it has to be curled in a certain way or it continually beeps with no green LED and doesn't supply power. I keep this one at home where it doesn't need to be moved. New properly working ones haven't beeped at all, so maybe ask Dell about that.And it does get hot, it's a 90W adapter and draw goes above 70W during games.
I would leave battery out but the AC cord falls out far too easily. Even being in 100% of the time it's only degraded 50% in 2+ years according to RMClock. Not too bad, still manages >1.5 hrs light use (6cell 56Wh battery in a Vostro 1500).

How to solve noise for laptop AC adapter&Notebook AC Adapter
My new Dell Studio 15's laptop AC adapter is making some buzzing and beeping noise. The sound varies if I use the laptop with or without the laptop battery. Anyone experiencing this? I don't feel comfortable with this noise from inside of the laptop ac adapter. Also it's kinda hot, I don't know if this is normal as I never had a laptop before – this is my first lappy.Also, is it OK to run the laptop without the battery? I won't move around with the laptop it will stay on the desk with power cable plugged in 24/7.
My friend jason tell me that It is normal to have some buzzing sound. as his notebook's AC adapter has it too, along with many other people. Just keep it on a cool surface and have some cover between you and it. I very doubt it would fail/explode but just in case.Generally that's what you should do, but have the battery charged at around 40% before disconnecting it. that's the most optimized % to store the battery (or was it 60%? i cant remember >.< ). also, store it in a cool place; or the fridge if you're not planning on using it for a LONG time.If you have the battery and AC connected to the laptop, it will trinkle the life of the battery, slowly to it's demise. Which actually dies a lot faster.
Below is some method for you keeping you laptop ac adapter to be used much more better according to Dell:
Charge batteries before storing. The recommended charging time should not exceed 1 hour. Typically, this should charge the battery to between 80% and 100%. (Some discharge will take place over time. Stored batteries are expected to discharge 10-15% over a four month period, for your information.)It is normal to have some buzzing sound.

Without battery when use laptop AC adapter
I've run other laptops using the Notebook AC Adapter while the battery was not installed in the laptop. Never seemed to cause any problems. When I do this with the XO I notice the adapter gets warmer then any other adapter I've used. Is what I'm doing harmful to the XO or the adapter?I run without the battery at home so when I take the XO away from my desk I know the battery is fully charged.
My friend Jack has run one XO without the battery for about 10 hours per day, 7 days a week for a year and there does not appear to be a problem. His power module runs no hotter than the power module on his Linksys wireless access point, Linksys router or cable modem; however, the display is at minimum brightness or blanked most of the time. The power module does run hotter than the others if a discharged battery is charging and the XO is being used.
So I'll bet the hot adapter only happens when I'm using it and charging the battery at the same time. Of course,if I want to buy an new notebook ac adapter,I will go to laptop ac adapter online store buy it.Below is the most popular online battery stores:

Laptop AC/DC Adapter Power Supply
The manual for the XM1 includes diagrams for using the crossover in a car. From the manual:
The XM1 can also be used with the sound system of a car. The problem here is that most cars have a single 12 volt battery as a power source, and the XM1 requires positive and negative supply voltages. Figure 9 shows a simple solution where the 12 volt supply is used directly to drive the crossover; the ground reference is derived from the battery voltage through a simple voltage divider. This circuit works well if AC coupling of the signals is allowed and the signal levels do not exceed 2.5 volt RMS (4 volts peak).Resistors R1, R2 and capacitors C2, C3 remove noise signals from the power supply to avoid alternator whine to be passed on to the output signals. R3, R4 and C4 define the ground reference for the crossover. The input signal is AC coupled with C1, and the output signals are AC coupled with C5 and C6. Using film capacitors for C5 and C6 should be considered with high performance systems.
If the power source is a 20 VDC laptop AC adapter: 1. Would the AC coupling capacitors (C1, C5, and C6) be required?2. Would R1, R2, C2, and C3 be required?3. What voltages would be available at P2 pins 1 and 3?
I like to house the XM1 module and the voltage divider circuit (R3, R4, and C4) in a small project box and use the laptop AC adapter as an external power supply. Would this configuration perform well in a bass guitar amplification system with nominal 1 volt line-level inputs and outputs? Still waiting for the xover board to be delivered but the enclosure and power supply are ready.
AC Adapter can’t supply power for laptops
My wife's laptop doesn't react to having an laptop AC adapter plugged in, but it can still run off of battery. (I charge her battery in my laptop and all is well, but that gets old quick.)Any ideas as to what could be causing this?
I popped it open and didn't notice anything popped or burnt, all the traces seem in tact and the capacitors are happily sitting there without so much as a bead of capci-juice running down the side.I'm hoping to be told "oh, that problem, just shake it this way, spray some air here, and off you go", but so far HP has just been telling me it is a $400 job and I have to wait a month to get it back.
Is this a new laptop or an older one? After two and a half years, my laptop's AC adapter went bad. There are stress points at various points on an adapter. Go to a local retailer w/ a decent return policy and buy a universal power adapter. They usually come with a transformer, an AC plug, and another cable that goes to the computer. It should come with a variety of plugs for various laptop brands.
Buy one (I use a Targus adapter) which is capable of putting out an equal or greater power output as the one my wife has. It should say it on the adapter itself. I don't remember how I determined my laptop's power requirements. I think I took it from the laptop battery's voltage and amperage stats.Anyways, if this doesn't work, then you can rule out the AC adapter and figure out what to do next. But changes are that your AC adapter will fail sooner than the laptop's motherboard power plug header.

Cell Phone Battery Charger to charge a lithium ion battery
Does anyone know of a good external battery charger to charge a lithium ion battery?I am the unfortunate owner of an NOKIA N97 phone which has a rapid battery drain issue when it is turned off.
I don't like removing a perfectly good battery in order to reinstall a totally dead battery just so I can charge it in the phone. Beside the fact that it's a nuisance, I'm concerned about wear on a flimsy plastic part that was not designed to be opened & closed on a frequent basis. I tried a Universal charger that is made in China (come to think of it everything is made in China these days ) and it broke the 1st day before it had completely charged the battery even once.
Verizon doesn't carry an external charger, and Nokia doesn't make one. Any info you can pass on would be helpful and appreciated.
Though it is completely overkill for one battery, there are various battery charging products made by a company called Cadex that would charge, test and recondition (NiCd/NiMH) just about any type of battery. You may find one cheap on www.battery-replacmeent.org or somewhere because these are somewhat pricey new.
Another idea is to find the same phone on www.battery-replacement.org/cell-phone-batteries.html or Craigslist and use it as a battery charger only.
How to conserve camera battery power?
Your cameras battery life is very important. Without battery power you can quickly become useless. Here are some tips for making your cameras batteries last as long as possible.
Buy the Longlife Battery
Buying an additional long life battery is the easiest way to ensure that you have enough battery power to get you through your event. When you buy a long life battery keep your original battery charged as a spare for emergency situations.
Camera batteries can lose charge when they have been stored for a long period of time. Even if you stored the battery at full charge plug your camera in the night before to make sure you get the most you can out of the battery when it matters.
Use the Viewfinder
Using the LCD screen can be tempting to do when you are recording an event. The LCD screen uses more than twice the battery power than your cameras viewfinder does however. If you are in a situation where you want to conserve your cameras battery power then try to close the LCD screen and use the viewfinder instead.
Watch Your Movie Later
It can be tempting to want to watch the funny event you just recorded. If you wait and watch the event later once your camera is plugged in then you will be able to save your battery power for recording more fun events.
Make Your Movement Uniform
Turning your camera on and off and zooming in and out can take up a lot of battery power. You are going to want to zoom, and turning your camera off when you are going to stop recording for a while is a good idea. Try to keep things like that to a minimum when you can.
Buy an External Battery Charger
If your camera uses itself as a battery charger then you may want to consider purchasing an additional external battery charger. If you have two batteries then you can leave one on the charger in the hotel room while you and your family are out for the day, stop back by in the afternoon and switch the battery on the charger for the battery on your camera. With an external battery charger you are able to have a battery constantly charging and also always have use of your camera.
