My IBM2611 laptop, spent more than three years, and the battery has not been looking the other. The last six months, the ability to supply energy to the battery deteriorates, watches today for a test, actually use just 20 minutes. Originally wanted to purchase blocks of new troubles, never thought to inquire about a blue accessories Monopoly Express, I would like: Battery lithium-R2611 850! My machine is that now the value of money? To put an aftermarket battery sold 350, said Paul month, but a month later?
There is no way the reader access to the chat bar Qiujiao web master. In various forums laptop or a Web site, anywhere on the old battery cores for the introduction, there are specialized to make the live dealers. A battery of 10 to 25 months. However, since I use the battery from IBM, there are eight nickel-hydride batteries, metal, calculate required at least 100 bar yuan. Although the 100 is a side dish, made after the event No, not even 20 minutes of the original disappeared. Can not take the risk.
At that time, the Forum has a master above me in my mind: Ni-MH battery memory efficiency is very obvious, perhaps you should first try to discharge, and then decide what to do. I sent for multimeter, battery measurement in 2611 is negative, the battery of both ends of the interface is positive and negative. An amount of voltage is 10V, the voltage seems normal, completely discharged, the battery is still great potential responses.
Now, on the implementation of the landfill. Disconnect the AC charger, start the computer to see if the display power: 98%, open Winamp to play MP3 files, listening to 20 minutes, the computer prompts the preservation work. Showing 1% of electricity right now. The computer hibernates in soon. Stop, remove the battery, a voltage test, strange 10V! If he found two small 6V emergency bulb connected to a power supply, unusual light bulb, then such a bar to lie, after nearly two hours, the lights finally went out (and later found burnt out). The battery is installed, connected to the mains, boot, power management, the display is over, about 5 minutes, even charge 60%! How is this possible? ? ? Almost a half-hour of electricity filled. Start “Battery
Bar tests that showed that 100% of electricity, unplug the AC charger, battery
Bar shows 98% battery remaining, estimated time of 3 hours 10 minutes. Feel happy, but my heart: “Is this the list? Too easy a bar! “Start Winamp songs, but you have not seen the 10 minutes we heard the alarm sound!” Shortage of electricity, please change the battery. ” Capacity is displayed as 3%, then the computer goes into sleep mode. The battery took only 10 minutes, remove the battery, a voltage or 10 V, seems to release any means, connected to the bulb slowly wait. 5 minutes or so, the lights go out, a test voltage is still 10V. How Gaode, release to let go, it seems that unless you can not see the light bulbs burned! This seems not acceptable.
I installed the battery, disconnect the AC power, start the computer, you can even start! Consumption is still 3%. Then the sound of the alarm quickly, the computer in sleep. Now, I fell into meditation.
Since the battery is still able to boot the computer power is sufficient to show up. Shortly after launch, in sleep, the battery discharge is not stable, no power has been exhausted. So sure the remaining power is enough to start the computer. Better yet, try this: the computer to sleep, click the mouse to turn in a moment like a computer during sleep to activate it again, so that the effective discharge may be a little better. In this way the computer to sleep once every three minutes, time of day. Stir for 45 minutes, the computer may not be the last wake. Remove the battery, this voltage is below 5V, drawing a line on a 6V bulbs, to continue to discharge until the lights off, it must be said that the discharge of success.
Re-install the battery, connect AC, startup. Power Management Display: is in charge of electricity 1%.
I open the Word to prepare to write this article, noted that the display of the battery is still at 1%, but felt the position of the battery a little heat, it should be supported. Waited for 1 hour and 50 minutes, the display power of 43%. I really can not go on and so first test to say.
Disconnect the AC charger, start “Maximize Battery Wizard” to set the battery energy savings average (CPU Speed: CPU speed to medium Medium LCD
The most brilliant display brightness EVEL 7), have begun to measure the battery life, the program runs in the background Winamp, Word. The CPU usage to 100%.
Power output relatively stable, just started from 43% to 37% of the time by two points from 37% to 31% long term and 9 points from 31% to 25% of the time and 9 points from 25% to 3% of the time 10 minutes. The actual use of the battery 30 minutes, consuming electricity of 40%. If the proration of the fully charged battery must be able to use 80 minutes. At this point the battery has declared a perfect return.
Such a result is indeed so I was surprised, not expecting such a way to actually be able to approximate the original is to my old batteries glow a second spring, which is also a sense illustrates the quality of laptop batteries IBM. If you and I have the same scourge of books users can try IBM .
