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 ?

Batteries are not repairable.

 

If you are referring to the laptop's power battery, most are held in place with a couple of spring loaded finger clips, just slide the clips sideways. some are located with two screws, undo the screws and it will slide out. Some - Lenovo I am looking at you - are internal and cannot be accessed without at least partially dismantling the laptop.

 

If you are referring to the CMOS battery - typically a CR2032 lithium cell - these are always internally mounted and replacing them may involve anything from undoing one or two screws and removing an access panel to a complete teardown just to get at them.

 

I don't understand the connection between faulty batteries and flashing an EEPROM.

Thanks for your reply. You are some beginner in the world of computers as soon as you do not know about the repair of batteries. What have you repaired so far?

I would suggest that you think before you post.

 

Someone with in excess of 6500 posts, that is a member of staff here (as am I), knows more, a lot more, about computers and their intricacies than you do.  The reply you received, and your response to it, clearly indicates this is the case.

twi_x, many competent computer technicians have no reason to be aware of the internal intricacies of smart batteries, charge controllers or SMBus management.

 

But why would any who are aware, be motivated to offer help when they've seen the first responder get a dose of cynical rudeness?
