When laptop battery works for a long time, it's hard to charge electricity fully, and even it shows that the battery is damaged. The fact is the increasing resistance. And the voltages raise up faster. This easy to identify as full, then capacity will naturally decline. As the larger battery internal resistance, discharge voltage drop at high speed, so the system is easy to mistakenly think that voltage is without enough power. So we should take steps to save this.
Big brand laptop has a battery refresh program; we can use it to repair the battery. As the notebook computer: notebook computers equipped with nickel-metal hydride battery (Ni-Mh), like mine is HP 446507-001 Laptop battery. I usually discharge it improperly; so the battery discharge time is short, only less than 5 minutes. If carrying a laptop to work, then it is very inconvenient. What can I restore the battery's discharge time? BOSCH Power Tool Battery DEWALT Power Tool Battery
We can use the official laptop website which has launched a battery refresh program to refresh the batteries, to recovery its discharge time.
(1) Using AC power to support the laptop, first download the refresh program from official website.
(2) Restart your computer, press F8 to enter boot menu and select safe DOS mode.
(3) Entering the download file, start the battery refresh program, and reading the warning message, inserting the floppy disk as required, and then press the Enter key to the implementation of the self-extracting operation.
(4) Boot floppy disk with this computer, the screen came up with reference information.
(5) Unplugging the AC power, the program will automatically be on the Ni-Mh battery discharge, discharge is completed, and the system will automatically shut down.
(6) The battery temperature is high at this time, should not immediately start, after a while to cool the battery, plug in AC power.
(7) Boot the computer with a floppy disk, the file will automatically run the refresh program, and ask the user whether to proceed.
(8) Then refreshing process began to refresh the battery, very soon, when the return to DOS prompt A:> , it represents that refresh is complete.
Before the HP's watergate issue, HP captured a large part of China market. Thus it did have some advantages that others should learn from. Here we list some obvious factors:
Brand. Purchasing anything these days have involved brand for a lot of people when they encounter a variety of stuffs. Hewlett-Packard (HP laptop) in worldwide sales is on the top, and in Zhong guan cun is the same situation. These fully demonstrated its overall strength. Some proud managers prefer this brand and take it as the representation of their high image. Hewlett-Packard or IBM is their choice, they emphasized the cost is not Asus. The ordinary people they would rather get hp than economical Asus for the sake of their face!
Update quickly. They update a series of configuration almost every two to three months. The mold release is endless, every six months launches a new mold. Each time brings some fresh blood, such as HP Pavilion DV8000, I was out of date after three months for there were new model came out and replace this one. And this laptop which equipped a 394224-001 AC Adapter has been changed for three times. When new series came out, there must be some new improvement.
