Power Laptop Could Get New Life

serg — Sat, 27 Dec 2008 20:10:13 +0000

The tech world is developing quickly, and so is the laptop power technology. The today’s result of laptop power packs research is a gradual switchover from lithium iron batteries to portable fuel cells.

Media Bay Fuel Cell

We can trace the respected activity of some power source makers and be aware of what we are to have soon. For instance Panasonic’s purpose is to create a methanol fuel cell enabling a laptop to work for 20 hours, but this promise is planned by the company only in two-three years.

The more working hours for cell-phone talk is already offered by Medis Technologies Ltd., it has issued a 1-watt liquid borohydride fuel cell recharger with the above-mentioned potency. But the 24-7 Power Pack when exhausted has to be recycled, not refuelled.

Anyway some analysts do not expect the wide commercialization for fuel cells, the switchover will go a bit at a time. The new technology should be standardized. And nowadays some companies manufacturing laptop power units are moving toward their products other than fuel cells, but enabling enlarge their capacity as well. For instance silver-zinc batteries are expected from Lenovo, and their capacity will be 20-30 per cent higher than that of a conventional lithium ion battery.

Laptop Battery Repair

serg — Tue, 16 Dec 2008 20:25:53 +0000

Most of laptop users ask themselves a question – if it possible to repair a laptop battery after it has undergone wear and tear.

Laptop Battery Repair

First of all it is recommended to consult the internet to know what kind of battery could be repaired. But one needs to know a battery which is apt to leak should not be repaired, as it could be unsafe. But most batteries have the complex construction and therefore cannot be repaired at all. Some batteries can, but for that one should have specific tools. It is much cheaper and more wisely to buy a new one.

Notebook Battery Removal

Sometimes a damaged battery just needs a little calibration. Such work can be done in local laptop repair shops. But if a battery is really damaged, one should better throw it out to save money and nerves. Therefore one should be aware of the type of the battery when he is going to have repaired, or firstly to check the possibility of such repair in a store before buying.

But one must remember a laptop battery is one of the most important parts in a unit, and taking care of it is the quite rational thing.

MacBook Battery Testing

serg — Fri, 12 Dec 2008 14:21:03 +0000

A notebook battery of Apple’s MacBook’s is designed so that it can save up to 80% of its primary capacity within about 300 full cycles of charge and discharge. So we can resume that the longer we use the battery the less charge it gets during a sequential cycle. To follow the process of decreasing capacity we should have a tool for its analysis. We wonder if the Apple notebook has such a tool. As we have found out a 15″ MacBook Pro has got a built-in diagnostic which is able to analyze battery’s life.

MacBook Battery Charger

It is easy to make the test operation. We opened the Apple menu, chose About This, clicked the more Info button Mac and found launch system profiler. It also to be found in the utilities folder. Then one can glom the Contents window in which there is battery line, and the first entry battery Information is what we need. In some other models, like Leopard, Tiger one can choose cycle count or condition entry in the health information.

In nowadays models must have good pane in the condition, if not, it is necessary to contact Apple and clear out the reason of is absence. The up-to-date Apple’s users would like to have the needful current battery statistics, the battery original and present capacity, actual charge, charge cycles, running voltage. All this he would like to see in an interface.

Long Life Battery Of Boston Power Offered by HP

serg — Thu, 11 Dec 2008 15:22:04 +0000

Each traveller limited in time would not like to spend it near an outlet to charge his laptop battery. To improve the lives both of a battery and of a customer Hewlett-Packard is introducing into the market the innovated Sonata battery, which has been developed for three years by Boston Power. HP will soon rebrand it as the Enviro battery and offer for some separated units.

Boston-Power’s Battery for HP Notebooks

It will take only 30 minutes to charge the battery to 80%. The number of charges before the battery’s exhaustion is 1000 instead of common 300. A user can charge the battery each day and stand with it for as much as three years, and even four years, if to charge only on weekdays. This battery will appear firstly in the USA and Canada and then it is planned to be distributed in other markets. HP has been working together with Boston Power for three years and now it is its first major customer.

Christina Lampe-Onnerud, founder and Chief Executive Officer of Boston-Power, believes that Hewlett-Packard will acquire a lot of customers and will not stop its activity at this point of achievement, breaking into some other electronic industries. She says of the mentioned innovation:

“It brings a new level of performance to the market”.

Hewlett-Packard guarantees the Enviro battery 3-year life at sum extra price. In early 2009 the product will be already seen and tested by the customers of the company.

Battery Life Is To Be Increased

serg — Wed, 03 Dec 2008 16:44:31 +0000

A department of OLPC project, making the screens for XO machine, called Pixel Qi, plans to furnish laptops with battery which lives can last for 20-40 hours. Mary Lou Jepsen from Pixel Qi believes that this innovation will be introduced in the first half of the next year.

Jepsen says: “We are working with a number of notebook and e-book makers on a number of different form factors”. The company can enable an increase of 5-10X battery life from one charge to another unlike a standard notebook. An owner will have the possibility to recharge its batteries in the interval of 20-40 hours instead of a few ones as usually.

The poor battery life is a weak moment of the current devices. Even seven hours use, offered by the Sony Vaio TZ and some others, are not enough for the laptop owners of today. So they do hope to get soon increased battery life, and Pixel Qi is one of those to live up their hopes.

Toshiba Slim Battery

Moreover Jepsen talks about their intentions to make their screens cheaper, but unfortunately cannot reveal the secret of what stuff is to be used in these screens, but everyone can find it reasonable that it will have some similarity to that used by the XO.

Flash disks increase laptop battery life?

Laptop Expert — Fri, 23 Nov 2007 05:43:45 +0000

Laptop PCs need longer battery life. I used a flash-disk based laptop for much of the ’90s and loved its 10-hour laptop battery life. You just have so much more freedom when you don’t need to worry about keeping a laptop battery charged.

I’ve been very interested in how flash drives could extend notebook battery life. Using a Kill-a-watt power meter I ran some experiments with an Intel Core Duo notebook. Power use is a little more complex than I’d thought. Here’s what I found.

Laptop config:

MacBook with the 2 GHz Core Duo,
2 GB RAM,
Intel 950 integrated graphics,
13 inch screen,
8x DVD Drive,
160 GB Western Digital Scorpio 2.5″ 5400 RPM HDD,
Bluetooth,
Wi-FI

One of the nicest things about the MacBook is that disk drive removal is easy (see the 1 minute video here). I ran the tests with the internal Scorpio drive removed and ran the MacBook off an externally powered FireWire drive.

Instrumentation
In addition to the Kill-a-watt power meter, which sits between the wall power and the MacBook’s power adapter, I also used the most excellent open source MenuMeters utility. MM shows CPU, memory, disk and network usage, typically sampled over a user-selectable 1-2 second period…

The Tests
I booted the system while video taping power usage with both the internal and external disks. I also ran a disk defragmentation tool, the estimable iDefrag to create heavy disk I/O.

Since I had the system up, I also checked some of the other subsystems. Display power consumption was measured with the display off and at minimum and maximum brightness. Optical drive consumption was checked by watching a DVD and ripping a CD. Idle power consumption with the screen off and CPU at 3-4% was also checked. I even removed a 1 GB SO-DIMM.

The Results
The surprise is that you can’t just turn features on and off to judge power use. For example, performing I/O is a CPU involving business whether to disk or over Wi-Fi. In my defrag workload the CPU utilization ran from 80-95% on both cores, for an 8 watt hit – almost 3x of a busy disk…

30 year laptop battery life? Yeah, right

Laptop Expert — Sun, 21 Oct 2007 17:31:56 +0000

Wow! It’s Wednesday’s IT Blogwatch: in which we’re really, really excited about a notebook battery that lasts 30 years. Not to mention an awful, awful performance from Commander Riker hawking enterprise IT automation software…

A breathless Next Energy News reports:

Your next laptop could have a continuous power battery that lasts for 30 years without a single recharge thanks to work being funded by the U.S. Air Force Research Laboratory. The breakthrough betavoltaic power cells are constructed from semiconductors and use radioisotopes as the energy source. As the radioactive material decays it emits beta particles that transform into electric power capable of fueling an electrical device like a laptop for years.
…
Betavoltaics generate power when an electron strikes a particular interface between two layers of material. The Process uses beta electron emissions that occur when a neutron decays into a proton which causes a forward bias in the semiconductor. This makes the betavoltaic cell a forward bias diode of sorts, similar in some respects to a photovoltaic (solar) cell. Electrons scatter out of their normal orbits in the semiconductor and into the circuit creating a usable electric current… [more]

Addy Dugdale digs it:

Made from radioactive material … the batteries end their life being completely inert and non-toxic, so they’re not as scary-bad as they sound … Before you all run for the tinfoil, the batteries don’t use fission or fusion, nor are there any chemical processes to produce energy, which means no radioactive or hazardous waste … Small and thin, the batteries use a porous silicon material to collect the hydrogen isotope tritium that is generated in the process. And as it’s a non-thermal reaction, your laptop will stay cooler than if its juice came from traditional lithium-ion batteries… [more]

Rupert Goodwins, the first ever blogger scoffs:

Sadly, no. As with the best techno-rubbish, there is a story in there, but you’ll be pootling around the skies in jetpacks before you’re powering your Dell from neutron decay.
…
Tritium’s half-life is around twelve years, so every decade or so your battery will halve in power … the sort of atomic structures that generate power when bombarded with high energy electrons are the sort that tend to fall apart when bombarded with high energy electrons … there’s the small problem that if you break the battery during its life the nasties come out … they don’t have a great conversion efficiency. Around 25 percent is the best you can get – which is pretty good, but leaves 75 percent sloshing around as heat. That means a 25 watt battery will get plenty warm … Even the latest devices, which are very clever in the way they saturate a porous structure with the gas and thus usefully capture quite a large number of the energetic electrons, have an energy density of the order of twenty five watts per kilo. Lithium ion batteries, the sort you have in your laptop, manage 1.8 kilowatts per kilo… [more]

Care for Laptop Batteries

Laptop Expert — Sun, 21 Oct 2007 17:24:19 +0000

Lithium Ion notebook batteries wear down because of two factors:

active usage in your notebook battery
natural aging of the notebook battery

Both will wear down your notebook battery over time; the trick is to minimize their impact while still getting the performance out of your laptop battery that you need.

The most important thing to understand about laptop batteries is that they are always losing a small bit of their charge. The hotter the temperature, the faster notebook batteries loose their charge. So rule number one is: keep your notebook battery cool. Notebook battery manufacturers store their products at around 60F.

The second most important thing to understand about notebook batteries is that their capacity decreases with each cycle of charging and discharging. By itself, this is not surprising – but when combined with the previous point, it leads to a surprising conclusion.

When laptop users leave their laptop battery inside the machine but leave the computer plugged into the wall, the laptop battery is going through a constant charge-discharge cycle. The notebook battery is sitting unused inside the notebook, discharging a little faster than normal because of the notebook’s heat. Once its charge level drops to a predetermined level, the AC adapter provides extra juice to “top off” the notebook battery. As the laptop battery gets older, it tends to self-discharge a little faster, which accelerates the process even further…

Lithium ion notebook batteries normally offer 600 to 800 charge/discharge cycles over 1.5 to 3 years of useful life. When you use your notebook battery as described above, you are needlessly using your supply of recharges.

One additional note: many people recall that older notebook batteries on early computers worked best when they were fully discharged before being recharged. While that remains true for Nickel Cadmium technology, today’s Lithium Ion notebook batteries work best when they are recharged when they still have 10 to 20% capacity remaining. So if you are using your notebook battery on a long flight, try not to get in the habit of using the notebook battery until it has almost no charge. Your laptop battery literally won’t be the same when you re-charge it the next time.

Some Guidelines for notebook batteries:

Remember that new laptop batteries generally arrive in a discharged state; you must charge them up for at least four hours before their first use.
Keep your laptop battery cool, but do not put it in the refrigerator or freezer
Don’t use the notebook battery if you don’t have to! Many people keep their laptop plugged in most of the time. They can preserve their notebook battery life by storing the battery outside the laptop in a cool place.
Try to avoid running your laptop battery all the way to zero
Don’t charge your notebook battery before long periods of inactivity
Much as we’d like to sell you more laptop batteries, don’t buy spare notebook batteries for later use. The longer you hold them, the less useful life they provide
