Dead laptop battery repair

[twi_x]

Hi,

does anyone know how can I repair dead laptop battery without opening and damaging. More precisely can anyone explain me which tool and software is used to flash her (EEPROM) memory ?

You are asking two questions. 

It should not be necessary to flash the EPROM on a laptop not yet three years old.
How do you know the laptop battery is dead?

Does the laptop work when plugged into the electrical wall plug?
Who told you to repair the battery yourself? Do you want  to die?
This is a scam:

DIY repair of batteries is only  for very advanced techies. . And eve then it is a real hazard to life and property.

EDIT: Laptop batteries area special thing. Thet differ from car batteries and flashlight batteries is a big way. They are much more dangerous.

There  is little value in resorting flashlight batteries. However, one can do a real business with automotive batteries.

There is a need for entrepreneurs to get into local automotive battery restoration. It is not easy, but it is a good business.

To be honest, this business of restoring old or dead batteries is not as easy as many think, but actually everything good comes with a little hard work. However, with the right resources and a few tools anyone can do it, and excel at it.

Does that help any?

Thanks for the answer, but you did not offer anything specific. If someone wants to do this job, he understands that he knows the basics. In my surroundings, there are services that do this job and earn good money, and of course they do not want to discover the way they do it. Some instructions may be found on the Internet, but the biggest problem is software and the device is used for this type of service. I hope that somebody will offer concrete answers and instructions, not just for their own benefit.

In our first post:

...repair dead laptop battery without opening

IMO you can not, except at a high risk  beyond was is reasonable.

The methods you will find on the Internet are very dangerous.
In general, lithium-ion batteries must be returned to the factory and recycles by a process tactfully takes apart  the battery and re-cycles important  materials.

Put another way, it would be safer to make fireworks in your garage rather than rebuild lithium-ion batteries.

Read it over carefully.

If the battery is dead. Buy a replacement. Dont mess with a dead battery to try to fix it there is no easy solution to fix dead batteries. They are designed to fail and be replaced or new computer purchased.

If the laptop needs a flash to the BIOS, get the tool and BIOS flash ROM file from the laptop manufacturers website. If a flash doesnt exist, then there is no flash for it.
