Sony CW series, battery drained by itself when the adaptor is unpluged

Hi,

I was wondering if this is a normal thing or not.

I have sony cw series with p8700 on it.

what I am asking is why the battery would drain by itself when the adaptor is not plugged in to the notebook?

so everytime I take this notebook from home to office, I always lose around 5% of the capacity while it's in my bag.

is this something normal? cause if I take the battery out and plug it back for example 30 minutes later, it still shows 100%. It is drained while it's plugged in to the notebook.


I am so curious to know if this is something normal with sony cause I've tried with dell, compaq and ibm. none of them has this issue.


thanks and sorry for my english...

 

This is a known problem with some Sony laptops. According to a Sony engineer that I spoke to it is absolutely normal to lose battery charge over night. I lose up to 17% overnight if I leave the battery installed and turn the laptop off. If I leave the laptop overnight in sleep mode it only loses about 7-8%. That doesn't make sense to me, but it has been like that for over 2 years now. If I am shutting down the computer (not putting it to sleep) I disconnect the battery and all is fine that way. Virtually no charge is lost that way.
It's all very odd.

 

yes, it's odd. but it's a normal thing?

any other sony user can confirm having the same problem like mine?


thanks

 

Other people with exactly the same laptop as me don't have the problem, but some do.

 

wow that's weird... do I need to claim this to the service center???

 

I am bringing this up cause I need to know about others opinion


thanks
