A fully charged battery is being drained despite the computer is not turned on.
Answer:
Due to the following factors, the Li-ion battery power of the computer will always drain.

The proper running of Real-Time Clock (RTC) and CMOS consumes internal battery power.
Once the battery is inserted, the computer will not use the internal battery to run Real-Time Clock (RTC).
  
The power switch of the computer models after PC97 (※) is a soft switch.
The switch does not control the turn-on or turn-off of circuit directly, but sends turn on or off power signals to the controller of power manager to perform the operation.
When the computer is connected with the battery or power adapter, the controller managing power is usually in galvanical state which consumes power.

※  PC97 --- Microsoft recommend users to use the hardware specifications which can guarantee the proper running of Windows 95、Windows NT or more advanced Operating System.
  
Using microprocessor to send signals also consumes power.
VAIO battery is equipped with the microprocessor to check the battery state (the surplus capacity of battery, the current value when the battery is charged or discharged, the temperature of battery and so on).


As mentioned above, besides discharging automatically, the battery power is still drained no matter whether it is inserted in the computer or removed.
Therefore, the battery power is consumed even if the VAIO computer has been turned off.



   * Both the microprocessor of battery and the Power Management Controller are running on power though the required amount of power is small.
     For Li-ion batteries of video cameras or computers of other brands, the same amount of power will be drained when used in the same way.

   * For different models of VAIO notebook, the power consumption remains the same, disregarding the status of the computers. For different models of VAIO notebook in the same status, the discharged power quantity is basically the same in a specific period.
     Therefore, compared to computers with larger capacity batteries, computers with small capacity batteries may run for a shorter period of time.

     ※  Besides the capacity of battery, other factors such as the aging degree or temperature will influence the time of totally discharging.

Please refer to the following example for comparison of computers with larger capacity batteries and computers with small capacity and the running time.

Suppose there are two computers with different types of batteries as follows.

   * Computer A: battery with 11.1V output voltage/4300mAh capacity
   * Computer B: battery with 11.1V output voltage/2000mAh capacity

Suppose the consumed quantity of power is 200mAH per day, what is surplus capacity of battery 10 days later?

   * Computer A ：4300 - 200 x 10 = 2300 (mAh) about 53%
   * Computer B ：2000 - 200 x 10 = 0 (mAh) 0%

Thus, computer B with small capacity of power finishes discharging first.

Dun be so humble.

Both of u did a great job solving all VAIO enthusiasts here.

Keep them up!

I have a question, dunno if it's related.
I wanna make my FW more cooler, any way to do that?
Using a cooler fan isn't help anything...

I saw some cooler gel pad, are those helping? As it's cool conductance & dissipate heat from the lappie base. But I believe it'll block the air vent at the base... Will this works?

Dun like my armrest getting warm (while in room temp without a/c).

Is this thing Windows7 supported?

U tried this out yet?

i recently purchased a Vaio S117GG. I found that the sound quality sucks big time. The volume is very low even after the volume control is already max. On top of that the sound quality is horrible.

Anyway to improve the volume and sound quality?
Thanks in advance.

Looks like so..

Sadly as Sony is the fore runner in the sound system and they could not even provide a decent one for their notebook. Mind you the S series is not the low end ones 

Hi all
I am planning to buy Sony Vaio VPCS117GG, any suggestion where I can get the best deal?
Any of you guys who has advice on whether I should buy this lappy or consider other brand/model?
TQVM

Owner of two Vaio's checking in here (:

But they're too old, so doubt they fit in xD

Vaio S and FJ. Both also half a decade old already.

Considering an upgrade to either a Vaio Z or Vaio E. Can't make up my mind. Any help available would be much appreciated

its depend on your needs. theres alot of other notebook you can consider which fall under the same category of S series.
head here for other choice: http://forum.lowyat.net/topic/1422707

-Thank you, Just bought EA16FG from Sony Centre in Low Yat yesterday.
So far so good and am loving this laptop.

officially joined the VAIO force!

got myself an VPCX127LG with the RM300 cash back (result RM4999), couldn't be more happier than that. i prefer the black one though, but travelling down to singapore + paying RM900 extra just for the black + 3G WWAN doesn't sound quite right...

planning to get the X size battery but pretty pricey...

Looking for battery BPS9.
Ori - RM800+ (too crazyprice)
Compatible one walking around lowyat plaza quoted RM300 to RM400.

Anyone here got contact to get at more reasonable price.

I'll have to second that. Really interested in the EA16 but problem is no discount/freebies that I can find anywhere 

Really? Brother's friend who works in Sony Bangi says that the staff price isn't much different. Bought one of the Vaio's through him last time and it came with FreeDOS, not a big discount either...

I guess Sony's are slowly becoming like Apple's product now? Fixed price here and there.

to all EA16 users..may i know where u guys download the latest ati graphic driver?..is it hard to find?..i read some of the post here saying that driver downloaded from ati website cant be supported on sony vaio...and are those driver posted on sony-asia.com always updated??..

can someone please clarify with me...i plan to get a EA16 soon

is this problem just for vaio tho or is it for all models which use ati?
