Simple introduce about IBM ThinkPad A20M Battery

First post by: www.itbattery.com

As far as we know, IBM ThinkPad A20M Battery like so much of the ibm range, has upped the memory to 2GB from the two 512MB modules of DDR 2 SDRAM featured in our version. It’s pretty light and portable and offers high performance and great media options (like the IBM ThinkPad A21M Battery). Basically, you get the best of both worlds, at a reasonable price.

Dell IBM ThinkPad R60 Battery Specs :

• Intel Core Duo T2400 / 5 Mb Cache / 1.83 GHz / 667 MHZ FSB
  
• 15.4″ Wide-screen XGA Display with Truelife
  
• 120 Gb 5400 rpm Sata Hard Drive
  
• 1 Gb DDR2 SDRAM / 553 MHZ
  
• 256 Mb ATI Mobility Radeon X1400 Hyper memory
  
• Windows XP Media Center
  
• 9 - Cell Battery

The Dell Inspiron 6400 is 36×27x4cm and weights a tad under 3kilos. It has a 15.4inch screen with display resolution of 1680×1050 that I am told is WSXGA+. The fonts looked a little strange but were very readable. Displaying folders gave the icons a rather larger separation but this was just a difference and not a problem.

The Intel Wireless card (Intel Pro Wireless) is very good using my standards. Dropped connections were limited and it was easy to use. You can easily shut it off when you are not using it by pressing Fn + F2. For this card, you can use the software Intel provides or the one Windows has, Windows Zero. I personally prefer Zero because it’s easier to use.


IBM ThinkPad T60 Battery life is very respectable. I wasn’t expecting much and I almost ordered an extra to go with it. Under normal tasks (WiFi on, 75% brightness, Windows Media Visualizations), the battery lasted about 3 hours and 15 minutes. With WiFi off, and playing games with low brightness, I was able to get about 3 hours and 34 minutes. I bet that you can squeeze 4 hours if you really wanted. It also can fit for IBM 40Y6797 Battery.


Regardless, the 6400 will likely stay on your desk for most of its existence. Its 2.8kg heft is far from feather-weight, and you’ll definitely start grumbling after walking with it for 20 minutes or more. It’s fine for shorter distances, but true mobility can only be found in a sub-2kg offering such as the IBM 40Y6799 Battery.

IBM AC power adapter type cannot be determined

The “IBM AC power adapter type cannot be determined” problem description

I have brand new IBM FRU 92P1139 Battery.


Battery fully charged, when I unplug the charger from the wall, but let the plug in the Inspiron for a while (let’s say a night), when I startup my computer, I get the message “The AC power adapter type cannot be determined. Your system will operate slower and the battery will not charge. Please connect a Dell 90W AC adapter or higher for best system operation” (needless to say that the power adapter IS a Dell 90W…).

Unplugging and replugging the adapter solves the problem.


The problem happens frequently at IBM FRU 92P1141 Battery, IBM FRU 92P1137 Battery, IBM 02K6651 Battery and so on.

Customer review :


My original battery worked for barely a year. Second one lasted 3 months, now it doesn’t work at all. I follow all the recommendations for preserving battery power. It’s a pretty cheap practice for Dell to try to make money off of repeated purchases of weak and bad batteries, weaker than IBM FRU 92P1167 Battery. Between the bad batteries and the bad customer service, I’m never purchasing from Dell ever again.

recalling and replacing all batteries

First post by: www.itbattery.com

As you move into the final weeks of the semester, we want to send a brief reminder of the dangers of certain laptop batteries. A Compaq Laptop Battery recall has been in effect since 2006, but there is still a chance that you are using a recalled battery.


We recommend that you visit your laptop manufacturer’s website to confirm whether or not your battery is safe. You can find information about product specific recalls at the following manufacturer websites:


Compaq Armada M700 Battery recall: http://www.itsbattery.com/Compaq-laptop-battery/Compaq-Armada-M700-battery.htm

A limited number of batteries in use with various Apple and Dell Laptop models are being recalled.? Apple and Dell are taking a proactive approach and recalling and replacing all batteries from specific production runs.

compaq AC power adapter type cannot be determined

First post by: www.itbattery.com

Concerning this problem, I was also disapointed with the limitations imposed due to the PSID signal on my Compaq Laptop Battery. So this is my solution.


OK the ID function is there for a reason, Dell designed it to help preserve the ( Compaq EVO N600C Battery) etc, but having emailed tech support with a request for a software override or some other solution to be able to switch off the PSID requirement, they either could or would not help. Just recommended I purchase (as people have said) more of their charging equipment etc. which I also think is a bit unreasonable.


They could easily update the Bios to allow user selection of this function.

Anyway, I ummmed and errred for a while, and then thought why not move the mysterious ID chip from the adapter to permanently inside the Laptop and disconnect the middle ID pin so the laptop ALWAYS thinks it has a correct adapter connected. Fine by me. And you can still adjust the power saving mode on screen anyway.


Now I don’t recommend this to most people as its quite tricky. I’m an electronics engineer and have experience with circuits etc. and it took me a couple of days to do it with Compaq EVO N610C Battery. Remember warranties probably go out of the window.


The first problem is to get your good Compaq EVO N620C Battery apart. The case is glued together, and withought butchering it completely, takes some effort to get apart with blunt knives etc. Then unsolder the end of the metal shield nearest the output cord to get to the back of the circuit board.

creating a jacket around the cable

  First post by: www.itbattery.com

First you will find this: Compaq Presario 1200 Battery, Compaq Presario 1800 Battery, 116314-001

There are many small silver wires creating a jacket around the cable. After a few of them break from bending the cable during NORMAL usage there is a drop in voltage but still PLENTY to run and charge the computer. The whole thing about the CPU running at a slower speed is totally unnecessary and only there to further encourage a new purchase.


The wiring and AC adapter are DESIGNED to fail. I have never had one last longer than about a year. Oh, and if you try to get a non-Dell adapter (universal) it won’t work either.My Compaq Presario 700 Battery has not the same situation.


This is basically an engineered weakness causing many (Compaq Presario 900 Battery) AC adapter orders and a borderline scam if you ask me.


There are many small silver wires creating a jacket around the cable. After a few of them break from bending the cable during NORMAL usage there is a drop in voltage but still PLENTY to run and charge the computer.


Start laptop as normally with AC supply, after complete booting of system, turn off AC plug, just press the cable (coming from adapter) towards the adapter (with normal force) and Turn On AC. Surprisingly it’s charging my Compaq Laptop Battery.

Put it all back together, and it works well. I now get no more notifications of unrecognised adapters and full speed operation whenever I want.

How To Protect the Asus Laptop Battery

  First post by: www.itbattery.com

Is a composite standard lithium-ion Asus Laptop Battery (the power lithium), lithium power of the physical structure is characterized by high electricity, no memory effect. Lithium batteries must pass any battery power management controller (PMU), the effective implementation of the law charging control. Therefore,battery must be recharged using the original adapter, so as to achieve effective and safe application.


Lithium power is not the memory effect characteristics, that is not necessary to achieve the depletion capacitance charging, lithium power at any level of power, the right charged, the charge would like to charge, charge do not want to sleep on the consumption of automatic shutdown Also line up. Lithium electric charge to the general computing life cycle, the cycle is the theoretical value of 500 (+ / -15%), once considered a full cycle, spent 30% of renewable electricity charge, PMU will not count a cycle.

power battery and the PMU / SMC is the smart, as the depletion can not be 100% capacity, the PMU / SMC will continue to monitor the consumption level in a lithium battery, use up to 5% of the electricity that is, on its own Activate dormant books, forced shutdown to protect the lithium Asus A42-A3 Battery will not run out dead. At this moment should take charge for electricity market, lithium battery power adapter with PMU / SMC battery management controller, in charge of the resume will achieve 70% of the fast charge, 70% will be in place to achieve slow charge, 95% of the electricity to start Filling the implementation of drip, drip filling up to 100% charge off automatically.


Therefore, regular adapter to connect the original charge, is 200% no problem. The connection electricity in the city at the same time, lithium batteries, if less than 95% of capacity, charging adapter will be implemented to drop to 100% charge after the auto-off charge.


Notebook battery dismantling do not have to, is ignorance, lost mobility of the intent of the book, lithium batteries because of the long-term storage and failure, can not charge the implemented again.

Lithium-ion battery hybrid technology is expected to be reduced by half the cost of the battery

  First post by: www.itbattery.com

Ener1 CEO Charles Gassenheimer said that once its lithium-ion technology to accumulate up, it will be able to hybrid electric vehicle battery to cut costs by 50%. This has been with a major car manufacturers supply agreement signed by the company also said it At the end of this year is expected to get two new Apple Laptop Battery development contract. Those contracts may eventually become a production agreement.

Toyota's Prius-use nickel metal hydride batteries. However, lithium-ion technology, as well as a car manufacturer as a supplier to extend the power, the end result is a hybrid running away from the key. Is now in trial production of the Tesla Roadster electric sports car, as well as General Motors is expected to be released in 2010 to insert hybrid Chevrolet Volt are dependent on lithium-ion Apple M8403 Battery technology.



Ener1's Gassenheimer said that the assumption that crude oil remained at about 100 U.S. dollars a barrel, lower the cost of the Apple M7318 Battery means that 50% of the high price of hybrid car owners to buy a car in less than two years after the time they make the investment to break even, In contrast, now need 7-8 years.



"We can cut the cost of the PowerBook G3 Battery by 50% and I believe that information can be passed on to consumers," Gassenheimer said, "I also believe that we are able to break even point down to less than two years is obviously very favorable Because the U.S. car buyers is the popular choice in the 3-year lease. "



Gassenheimer said that if the decline in the cost of half of the lithium-ion Apple PowerBook G4 Battery can be no doubt on the mass production.

the terminals on the battery voltage

    First post by: www.itbattery.com

In constant current cycle, the Apple PowerBook G4 15inch Battery voltage sophisticated surveillance so as to avoid over-charging. As previously described, more than battery voltage termination will gradually shorten battery life, and its effects are cumulative in nature. As the battery ESR ends of the pressure drop in the CC charging, the battery terminal voltage show the Apple A1012 Battery voltage is not the exact instructions. Through the termination voltage to terminate the CC cycle, ESR on the pressure drop provides a guarantee that cushion, making the Apple M8511 Battery will not be too high voltage.

CC in the cycle, the battery was charged to its capacity of about 80-85%. CC after the completion of the cycle, a constant voltage cycle started. In this cycle, the Apple M8244 Battery I Charge = (VBatt - Vcell) / ESR under the charge. With the rechargeable battery, Vcell increased to reduce the charge current. The charge current decline as the result of the error caused by the ESR gradually decreased, and the terminals on the battery voltage show that the more accurately the actual Apple A1079 Battery voltage.
