While i was researching of Vaip P SSD information, I accidentally found the japanese blog discussed about modified latest BIOS file to enable the hidden BIOS menu.

Once we got the hidden BIOS menu and disable "S4 wake up", the battery leak should be fixed.

I translate English step by step only (all credits goes to original writer http://seamade.blog33.fc2.com/)

1. Download files 1,2,3,4 and save to Desktop.
①EP0000218377.exe
②python-2.6.2
③bios_ex_patch1.py
④bios_ex_patch2.py

2. Run EP0000218377.exe and it will popout "does not need to update" windows. Then, left the pop up window open, go to C:\Users\username\AppData\Local\Temp find out a folder with bracket { } with random number and letters. Copy the folder to desktop. You can rename it to short folder name.


3. In {} folder, there is a "Platform.ini". Open it with notepad. Modify as following.
[FDFile] BackupName=CurrentBIOS.fv
[Option] Flag=1


4. And then, In {} folder, run insydeflash. And click "Start" button. If you success, a file "CurrentBIOS.fv" will generated in the {} folder.


5. copy "CurrentBIOS.fv", "1.py", "2.py" three files to your user folder. (Because of access permission issue, it is better put all files in the User folder.)
C:\Users\username\CurrentBIOS.fv
C:\Users\username\1.py
C:\Users\username\2.py

6. Then, go to windows CMD command prompt, and runs two commands separately, one by one,
C:\Users\username> "C:\Python26\python.exe" 1.py CurrentBIOS.fv PatchedBIOS1
C:\Users\username> "C:\Python26\python.exe" 2.py PatchedBIOS1.fv PatchedBIOS
If you success, a file "PatchedBIOS.fv" will generated in the C:\Users\username folder.

7.Copy the PatchedBIOS in the {} folder and open "InsydeFlash.exe".
Click "option", "Update FV", "Enable", "choose file PatchedBIOS.fv", then click "update now".


8. After you click "update now", the InsydeFlash program will close immediately, but it actually running in the background. The writer suggested to wait 3 mins and Restart PC. (I waited 10 mins to restart PC)

9. Restart PC and click F2 to BIOS, in the Advance, you will see the hidden menu.

10. They suggest to disable "ACPI Table/Features Control", "FACP - RTC S4 Wakeup"

===========

Hi Jake,
This update is for 1st gen Vaio P only. VGN-PXX are japnese model. VGN-PXXX are US model. They are same BIOS.
EP0000218377.exe is the last BIOS update package of BIOS version R2073U3.
Update official R2073U3 first, then modify R2073U3 and update again to get hidden menu.

bios_ex_patch1.py and bios_ex_patch2.py are script only and you could rename the file. I just saved links as 1.py and 2.py files.

I tried, failed, and finally succeeded. Therefore, i could note procedure step by step. The photo is the hidden Bios menu in my Vaio P.
I installed win10 pro in my vaio P. But the battery % seems not accurate under win10 or either the battery is too old because of long time fully discharged.

Anyway, there is no more future update BIOS for vaio P.
It is worth to have a full BIOS menu. Once you got it, the BIOS menu stays forever.

Default Re: VAIO P(1st gen) BIOS hidden menu to fix battery leak
so now when fully charged you will not loose 10% of battery per day ?

I got 3x Sony VNG-P near me. One latest custom project 2 GHz Z550 Atom CPU.

I would love to use them, but I hate the battery drain when off....

What a great find!

I was able to download the first two files but I can't find bios_ex_patch1.py and bios_ex_patch2.py. Do you know what I'm doing wrong?

EDIT: figured it out, I think. On this page http://n-labo.cocolog-nifty.com/blog...-bios-7e5.html search for the two py files, right-click, "save link as," and that will save as a .py file. Is that what you did?

Also, since this is scary stuff, I want to make sure I have a first generation Sony P. I have a VGN-P588E. Does that model qualify for this BIO update?

2nd EDIT: from this site http://www.sony.jp/support/vaio/down...000218377.html the translation is: "VGN-P * 1, P * 0 "BIOS R2073U3" update program" with regard to the EP0000218377.exe. The machines listed are:

"VGN-P91NSVGN-P91SVGN-P91HSVGN-P61SVGN-P50/RVGN-P50/GVGN-P50/WVGN-P90NSVGN-P90SVGN-P90HSVGN-P80H/WVGN-P70H/WVGN-P70H/RVGN-P70H/G"

Again, many thanks for posting this info and for your helpful instructions.

Jake

Let me try again, i also have an extended battery. I personally like to use small battery because small battery plus power adapter weight are still lighter than the heavy extended battery.

1st gen vaio P will drain battery around 1 day 8% when the battery plug into the vaio, no matter the pc is "close lid", "sleep", "hibernate", "turn off".

2nd gen vaio P seems fixed this problem.

Many thanks for your follow-up. I now get the difference between 1rst and 2nd generation.

If you look here, at the official bios for the VGN-P588E, you can see Sony's reference to the

http://esupport.sony.com/US/p/model-...d#/downloadTab

They too refer to R2073U3.

Okay, I think I'm going to give this a try. I have a new extended battery and I dual boot to Win7 Ultimate and Ubuntu 10.04, and I use the faster Ubuntu 99% of the time.

With my current bios, the extended battery drains 4% daily--since the extended battery is twice as big as the regular battery, the drain appears to match a regular battery's 8% daily loss.

Wish me luck ,
Jake

Success: I can generate the same BIOS Advanced screen as yours.

It's amazing that you found these instructions and thank you again for posting such a detailed how-to.

HOWEVER, there is a key error in your second python command that I suggest you fix. Your command is:

C:\Users\username> "C:\Python26\python.exe" 2.py PatchedBIOS1.fv PatchedBIOS

The right command is:

C:\Users\username> "C:\Python26\python.exe" 2.py PatchedBIOS1.fv PatchedBIOS2.fv

If I'm not mistaken, you inadvertently left out the "2" in "PatchedBIOS2.fv"

[For safety sake, I would also use the ".fv" extension for all files]

It appears to me that the 1.py command makes PatchedBIOS1.fv. The 2.py makes PatchedBIOS2.fv and PatchedBIOS2.fv is the file to call when using InsydeFlash.exe in your Step 7

When I tried your python commands, I could not generate PatchedBIOS2.fv. I got a "file not found" error.

Here is the translation I used:

https://translate.google.com/transla...tml&edit-text=

Please correct me if I'm wrong. But when I used "PatchedBIOS2.fv" to update the current BIOS, I was successful.

I also waited TWENTY minutes before rebooting.

I'll post back after seeing if the battery drain is truly addressed.

Again, thank you taking the time to tell users about this hack.

Jake

Also, my .msi install of python-2.6.2.msi did not work with Windows 7 Ultimate; I got a win 32 application error--version 2.7 worked.

Unfortunately, I do not find that I've stopped the battery drain--I'm getting the same 4.5-5.0% daily loss. with "ACPI Table/Features Control", "FACP - RTC S4 Wakeup" disabled. Windows 7 shows a percentage point more battery than Ubuntu 10.04, but there's clearly a drain.

Although my extended battery is new, there is a chance that the battery itself is the problem. But recently, when I removed the full new battery out of the machine for 13 days and then re-inserted and booted machine, my battery was at 88%. So a drain, but not as quick as if the battery had been in the machine for 13 days. 13 x 4% would've been drained over half the battery.

As someonehoi says, the new BIOS page gives users many more options (you can even pick different LCD resolutions), but I don't think it solves the first gen Vaio P drain issue.

Oh, dear. I just bricked my VGN-P588E. Using instructions from this site:

https://translate.google.com/transla...p/&prev=search

I did tried these things:

"By the way, the changes are as follows.
Power in the OS options Advanced, sleep → wake timer to disable the permission of the
BIOS in
FACP - RTC S4 Wakeup: Disabled
PCI Clock Run: Enabled
Quickly S4 Resume: Disabled

PCI Express Root Port jackpot to the 1 to Disabled Arikamo also by people."

I now get a black screen on boot--the machine turns on, it accesses peripherals such as a usb cd drive, but screen statys black.

Does anybody have any advce?
