Help and Advice

Recommended Posts

Hi there,

I want build a Li-Ion Batter Charger I read about in a "SLAA287" document, to charge and old D638S battery.


I got an old D638S Laptop from someone. The person couldn't use it because of the dead(?) battery (DC 11.1V 6000mAH) or couldnt find an adapter/charger/power source to charge it with. I guess I'm in his shoes currently.


I dont know if there is any way to check whether or not the laptop still works (meanwhile) or not.


But, I am willing to try out the project (as per my title) anyway.


The SLAA287 includes a "block lever schematic", but not the component specifically. There could be a similar project ready to try (?).


I have another question but I'll create a new post for that...

Thank you in advance,


Could anyone advise assist me to figure out the componets and here to insert them?
