BIOS update crashed G530 4446-23U Win 7 32 bit

[Mike_NY]

I have installed latest BIOS upgrade from Lenovo  and my laptop crashed. (June 24 2011)

Will not boot, Lenovo restore doesn't help, can't boot from Windows 7 DVD

Does anyone know of a utility to create a bootable USB (or disk) BIOS flash

to roll-back to a working version of BIOS?

Lenovo G530 4446-23U, no HDMI support

Operating system: Windows 7, 32Bit.

try to remove the battery, unplug the ac power, press power button for 30-40 seconds, replace the battery and check if it works.

also, try to remove/replace or swap the ram sticks.

Did as suggested, no effect. Same problem remains

if you have valid warranty, contact lenovo support line and ship it back to service.

Yeah.... Warranty .... Thank you!

This is a solution which actually works;

It was recommended by a brilliant friend who is not associated with Lenovo:

1. create bootable usb flash drive

       here is a link to download wintoflash utility:

       http://download.cnet.com/WinToFlash/3000-2094_4-10974471.html

1. Unzip 6get19ww.exe to the usb flash drive to a folder (for example C:\SOS)
2. boot computer from newly created usb flash drive (if Windows doesn't work, use command prompt)
3. locate an old bios file on a crashed machine. It should be name bios.bak
4. copy located file to another folder with the name bios.wph for example (C:\SOS\bios.wph)
5. run WinPhlash.exe from a folder (for example C:\SOS)
6. specify backup file for existing BIOS as bios1.bak

1. specify new BIOS file as C:\SOS\BIOS.WPH

1. flash BIOS

Everything WORKS!

i was gonna suggest that if you don't have valid warranty.
( we've already discussed this issue before )

Mike_NY,

I'm a bit curious over your case. You mentioned that your machine would not boot up after flashing latest bios. Then how did you get it boot from the usb flash drive?
