URGENT!!! Bios Bug found for P500 series BIOS v2.90. TAIS really needs to fix this!!

Question

Affected unit: P500-ST6844 PSPGSU-0Q2012
I have had sleep issues with my laptop since I first purchased it back in 2010. I have made a previous post about it here: http://forums.toshiba.com/t5/Batteries-and-Power/L​aptop-turns-off-instead-of-going-to-sleep/m-p/3101​...
I recently found some some helpful troubleshooting documents for windows 7 power management on the Microsoft website.  One of the utilities it suggested to use is the PWRTEST.exe included Windows driver SDK. Running PWRTEST /sleep /s:4 results in a successful Hibernate cycle, however running PWRTEST /sleep /s:3 results in:
NO.0 Transition--TargetState: S3
Error: Pwrtest tracing might be buffer overflow, and the data of this power is discarded.
    File: d:\5359\base\power\tools\pwrtest\exe\pstrace.cpp
    Line: 1653
    Error Code: 0xc0000001
 importing pwrtest.etl created by the utility into the event viewer reveals bunch of these errors:
Unexpected GPE event was fired on GPE bits that should be disabled.

as well as this error :

doing reasearch on the first error reveals that this is caused by a bug in the BIOS.
the bug causes either one of two things two happen P500 does not enter Sleep (S3) properly, or when S3 is attempted the unit appears to enter S3 successfully, and the led sleep indicator blinks, but when trying to resume from S3, unit starts up from an off state and hangs after Toshiba bios screen is displayed. normal boot operation only occurs after forcing a power down and restarting unit.

Answer 1

Anyone running windows in the same laptop can check the same issue of battery drain due to WOl being enabled by default - in the Device Manager under the network cards, opening the settings menu for the ethernet wired card the default for Wake-on-LAN on my computer was set to enabled. This can be changed to disabled, and you may need to also disable the setting for Wake on Magic Packet. Also in the Power Management tab it is possible to uncheck the settings for "Allow this device to wake the computer" and "Only allow a magic packet to wake the computer"
In my laptop these were all set to enabled by default.
