ibm laptop Battery Maintenance and User Instructions

IBM Laptop Battery Maintenance and User Instructions
1) A new battery usually maintains a discharged condition with very low capacity. It is highly recommended to fully charge new ibm laptop battery packs before using. You can refer to the users' guide of your electronic device for charging instructions.
2) A new ibm battery pack needs to be circled (fully discharged and recharged) three to five times to reach its optimum performance.
3) Rechargeable laptop battery will undergo self-discharging when left unused for a long period of time. Thus, it should always be stored in a fully charged state and kept in a cool, dry and clean place.
4) To maintain the optimum performance of a ibm notebook battery pack, it is highly recommended to circle (fully discharging and recharging) it at least once a month.
5) It is normal if a new battery gets warm when being charged or used. However, please pay special attention if the battery pack becomes excessively hot. This may indicate there is a problem with the charging circuit of the electronic device. Please consult a qualified technician if necessary.
6) New ibm laptop batteries are hard to be charged. Sometimes, your electronic device may indicate a fully charged condition about 10 to 15 minutes when the new battery pack is being charged for the first time. When this happens, remove the battery pack and let it cool down for about 10 to 15 minutes then repeat the charging procedure. Sometimes, a new battery will suddenly refuse to be charged. If this happens, a suggested solution is trying to remove the laptop battery from the device and insert it again.

How do you calibrate the battery for your sony laptop

Once the battery for sony laptop builds a memory, there is very little you can do to repair it. New, the batteries hold almost two hours of use. However, the battery to my sony computer will only hold about 40 minutes of a charge.

The drawback to the sony laptop (and a lot of the older laptops and a good number of the new laptops) is that there is not an effective system of power management. This is seen more often with cell phones, where there is a "smart chip" that manages the charging of the laptop batteries without creating a "memory" to the sony laptop battery.

I purchased a generic battery for my Sony laptop this week. However, when I installed it in my computer it would not work. An error message popped up saying my computer was going to sleep and that the sony laptop battery may be incompatible.

Customer support pointed me at the following web site:, which points out that Sony laptops are running a little software program called ISBMgr.exe that generates this error when you insert a generic battery. It appears to be the only purpose of the software, and if you disable the software the genereic battery for sony laptop works fine.

I paid about $100 for my battery, where a Sony brand equivalent would have cost $370.Sony is really exploiting its customers here.

4400mAh 3.5hr Laptop Battery For Asus EeePC Eee PC 4G 8G 20G 701

High quality replacement Asus Eee PC 8G(1G RAM) Laptop Batteries . This 11.1V, Li-ion Asus Eee PC Battery is rated at 4400mAh capacity and is 100% compatible with the original equipment.Fits Asus Eee PC,Asus Eee PC 2G/4G/8G laptop.

Physical exercise is important for maintaining physical fitness and can contribute positively to maintaining a healthy weight; building and maintaining healthy bone density, muscle strength, and joint mobility; promoting physiological well-being; reducing surgical risks; and strengthening the immune system.

Frequent and regular aerobic exercise has been shown to help prevent or treat serious and life-threatening chronic conditions such as high blood pressure, obesity, heart disease, Type 2 diabetes, insomnia, and depression. Strength training appears to have continuous energy-burning effects that persist for about 24 hours after the training, though they do not offer the same cardiovascular benefits of aerobic exercises. Exercise can also increase energy and raise one's threshold for pain.

There is conflicting evidence as to whether vigorous exercise (more than 70% of VO2 Max) is more or less beneficial than moderate exercise (40 to 70% of VO2 Max). Some studies have shown that vigorous exercise executed by healthy individuals can effectively increase opioid peptides (aka endorphins, a naturally occurring opiate that in conjunction with other neurotransmitters is responsible for exercise induced euphoria and has been shown to be addictive), positively influence hormone production (i.e., increase testosterone and growth hormone). Benefits that are not as fully realized with moderate exercise.

Exercise has been shown to improve cognitive functioning via improvement of hippocampus-dependent spatial learning, and enhancement of synaptic plasticity and neurogenesis. In addition, physical activity has been shown to be neuroprotective in many neurodegenerative and neuromuscular diseases. For instance, it reduces the risk of developing dementia. Physical activity is thought to have other beneficial effects related to cognition as it increases levels of nerve growth factors, which support the survival and growth of a number of neuronal cells.
Both aerobic and anaerobic exercise also work to increase the mechanical efficiency of the heart by increasing cardiac volume (aerobic exercise), or myocardial thickness (strength training, see Organ hypertrophy).

Not everyone benefits equally from exercise. There is tremendous variation in individual response to training: where most people will see a moderate increase in endurance from aerobic exercise, some individuals will as much as double their oxygen uptake, while others will never get any benefit at all from the exercise. Similarly, only a minority of people will show significant muscle growth after prolonged weight training, while a larger fraction experience improvements in strength. This genetic variation in improvement from training is one of the key physiological differences between elite athletes and the larger population. Studies have shown that exercising in middle age leads to better physical ability later in life.

Review: Asus Eee PC 4G — Wee PC Is Super Sweet

At two pounds flat, the Asus Eee PC is the smallest ultra-cheap PC on the market, yet it's arguably the most capable of the bunch. Design-wise, the Eee draws on Asus's long history of notebook design: It's altogether a solid and streamlined machine. People who don't see the display might assume you paid thousands for it. This ain't no Vista laptop, though: The Eee runs Xandros Linux and is simplified to the point of obviousness. Jumbo icons let you launch a web browser, Skype, office apps, and the like, all separated by tabs to let you know if it's "Work," "Play," "Internet," and so on. Linux n00bs won't have any trouble setting up wireless, managing files, and even snapping pics on the integrated webcam. On the downside, the Eee's diminutive size mostly relegates it to novelty status instead of business tool. The keyboard is too small for touch typing, and the screen is just too tiny to fit much information on at once. —Christopher Null

WIRED Possibly the best ultraportable laptop you can buy, and for a mere $400. Available in multiple colors. Serious hackers can go nuts and add extra apps and even install Windows or other Linux distributions. 4GB solid-state drive means no crashes when you drop it.
TIRED Two hours and 20 minutes of asus eeepc battery life disappoints considering the slimmed-down specs. Only 1.3GB free storage space available straight out of the box. Stiff (and tiny) mouse buttons.

How to keep a laptop battery efficient?

It is said that letting a laptop plugged to the AC with the laptop battery in can damage the battery. Is it really better for the long term battery-life to keep on charging and emptying it?
i search some data.and get the best answer as follow,i hope it can help anyboday who has the same question.

While not optimum… I don’t think it’s a huge problem given your convenience.Some say it may not last as long.

Exercise the laptop Battery. Do not leave a charged battery dormant for long periods of time. Once charged, you should at least use the notebook battery at least once every two to three weeks. Also, do not let a Li-On battery completely discharge. (Discharing is only for older batteries with memory effects)

finally,My husband uses 3 year old hp pavilion dv1000 battery and we've left it plugged in most of the time. Still works great and the battery holds a charge.

sitelinks for my

do you know what is sitelinks?

Google Sitelinks are a collection of links that appears below the result of a website. These additional links link to main pages of the website. They are randomly and automatically chosen by Google's algorithm.EG:

As an example, here are the sitelinks that you get for when you search for "laptop batteries":

Sitelinks only appear for general search terms. You'll get Sitelinks if you search for "laptop batteries" but you won't get Sitelinks if you search for a term like "sony laptop battery". Sitelinks show up most often for searches on brand names.

under the usual links:there are 8 links:

dell 1691p , hp laptop computer battery , acer laptop battery,dell laptop battery,camcorder batteries, sony camcorder batteries, new f4809a

How can you get Sitelinks for your website?
Unfortunately, there is nothing certain about Google's Sitelinks. The following factors seem to influence whether Google displays Sitelinks or not:
Your website must have a stable #1 ranking for the searched keyword. Other websites don't seem to get Sitelinks.
Your website must be at least 2 years old. It seems that younger websites don't get Sitelinks.
The number of searches and the number of clicks that your website gets for a certain keyword seem to be considered. Keywords that aren't searched often enough don't get Sitelinks. It also seems that your website has to get many clicks for the searched keyword.
The number of links that point to your website with the searched keyword as the anchor text seem to influence the creation of Sitelinks. Sitelinks only seem to appear for the main keywords of a website, not for all keywords for which a website is listed.
If your website meets these criteria Google might assign Sitelinks to your website for your most important keywords.

Here,I introduce my new website: sells discount laptop batteries for sony,acer,hp,compaq,dell,toshiba ..., camcorder batteries , digital camera batteries , pda batteries and 7" 12.1" Digital Photo Frames on the online .

matchbox pinhole

My first couple of 35mm pinhole cameras attempted to be panoramic, wide angle affairs, but this time I thought it would be nice to get back to the classic square format.
Here's my latest contraption which uses 35mm film to provide square images of 24 x 24mm. Using this size means that you can get up to 50 exposures on a standard roll of 36 exposure film. Now that's what I call economy!
The image edges suffer from distortion that gives a "Diana" quality to the pictures. In fact, the images look very "toy camera" like indeed, except that the pinhole allows some really good close ups due to the DOF of the pinhole.
It's also costs pretty much nothing to build - certainly a lot cheaper than a $100 Diana off ebay!
So far I've only run a single roll of colour film through it, which I then developed in B&W chemicals,so the results are a bit odd but they did prove it worked.
I'll be posting additional photos (colour too!) onto my flickr site, check it out.

All you need is a matchbox, an empty roll of 35mm film, some new 35mm film, some black tape and a bit of foil!
First, mark out a 24mm square exactly in the centre of the matchbox tray, cut this out with a sharp knife as neatly as possible. Or make it messy if you like, it's up to you. This provides the image frame, any rough edges or card fibres will appear on the image obviously.

Now get a black pen and color the tray black. Also stick a pen inside the front of the sleeve and colour that black too.

Cut a small hole, about 6mm square, in the centre of the sleeve. Try to do this as neatly as possible to avoid fluffy fibres appearing in the image

Now for the pinhole. The very short focal length means that the optimum pinhole size is small, less than 0.2mm. Make a pinhole in a bit of foil/drinks can using you favourite method (wont go into it here, search the web), and stick it over the hole in the sleeve.

To work out how far to wind the film, I make small "clickers" from bits of plastic (here that stuff used to bind documents). Cut a very thin strip and make a point at one end

Now take the full roll of film. Stick the curved plastic to the back of the canister so that the pointed end pokes through a sproket hole by about 3mm. As the film is pulled out of the cansiter, the plastic will jump between holes and make a clicking sound. (some more detail on this here)

Now thread the film through the box sleeve. Then, push the inner tray in so that the base of the tray with the hole in in presses against the film, pushing it flat and proving the square frame.

You also need an empty spool to take up the film. Ideally, this will still have a bit of film sticking out, otherwise you have to carefully open the canister with a bottle opener, fix the new film end to the spool and re-assemble. I've done this but its much easier to use a spool with some film sticking out!! Splice the film together with clear tape. Then, wind the film into the take up canister so that both canisters fit snugly against the matchbox. Make sure no film is visible at the back - you will use tape to seal this joint so you dont want to be sticking tape onto the film! NOTE - make sure you dont wind the film back into the full spool at any point, the "clicker" plastic may rip the film.

All that remains is to make the thing light-tight. Wrap tape around the joints between both canisters and the box. Make sure all sides are well covered. The tape does a suprisingly good job at keeping the whole thing together and stable!
Place a small piece of foam on the underside of the takeup canister then wrap tape over it. This gives some tension and stops the film unwinding withing the canister each time you wind on.

Now make a simple shutter, a bit of tape will work, but I prefer a sliding card shutter. The camera's now ready to take pictures! Find something suitable to wedge into the top of the empty spool to act as a handle to wind the film on, and count 6 clicks for each frame.
Check out to calculate the optimum pinhole size, and work out exposure times for the film you use.
Mine worked out at around f90, which gives fairly short exposure times with ISO100 film, a second or two in daylight.
Make sure you don't wind the film back into the canister with the plastic "clicker" attached - it will rip the film.
Here's some more images from my first test - note I didnt get the hole exactly square!
If you decide to make one of these please share your images, I would love to see them. If you are a flickr user I've created a group called Matchbox Pinhole - Please add your photos to the pool! :-)
