Cara nk reset bios utk laptop compaq C700 / CQ40 / CQ45 / DV4 / DV5 / DV6 / HDX18T

untuk apa reset BIOS?


This recovery method should also work for HP CQ40, C700, DV4t, DV5 DV6 & HDX18T
C700 use the file name IBL80HW.FD thanks to macakox for this info.
CQ-401AX and similar use JBL20HW.BIN or JBL20.BIN or 30FB.BIN (TBC). Thanks to iq-myst.
DV5 see http://forum.notebookreview.com/show...2&postcount=50. Thanks to dannyres.
DV6-1030us and similar use the file name either 3627.BIN or 3627.FD (TBC). Thanks to errodrigues.
HDX18T see http://forum.notebookreview.com/show...0&postcount=57. Thanks to raj85.

For (TBC) only one file name is correct so if someone can confirm the correct one, please let me know, thanks.

There are probably other HP models with an InsydeH2O BIOS not covered here, so feel free to ask for help.

The following is a discription of how I managed to
recover the BIOS on a CQ45-107TX
running the InsydeH2O EFI BIOS
using a USB thumb drive.


IMPORTANT !!!
Obtained the correct BIOS file, HP seem to provide many different BIOS's.
For instance the BIOS for CQ45-107AU is not the same as CQ45-107TX.

For the CQ45-107TX I used the Insyde BIOS version F.04 file 30F7F04.FD then

• Renamed the file 30F7F04.FD to 30F7.BIN and placed it on a USB thumb drive.
  
  Disconnected the AC adapter from the notebook.
  
  Removed the battery from the notebook.
  
  Inserted the USB thumb drive into one of the USB ports on the notebook.
  Didn't seem to matter which one.
  
  Held down the 'Windows' Key and the 'B' key.
  
  Connected the AC adapter.
  
  Pressed the 'Power' button on the notebook.
  
  When the LEDs came on, let go of power button and the two keys held down earlier.
  On the CQ45-107TX the touch pad LED came on as amber (disabled) instead of the normal white (enabled).
  
  After about 10 seconds the notebook started reading the USB thumb drive.
  While searching for the file the notebook beeped once a second.
  The number of beeps varied, depending on how big the thumb drive was and
  the number of files on the thumb drive, from just one beep to many.
  If the file was not found, the notebook would reset itself and try again.
  
  If the file was found then it took about 12 seconds for the notebook to load it.
  No beeping sounds heard during the loading time.
  
  When loaded the notebook started flashing, indicated by beeps every 2 seconds.
  This took about 32 seconds.
  
  About 5 seconds after the beeping had stopped the notebook shutdown.
  BIOS worked normally thereafter.

*kalau korang nk tau dgn lebih tepat,korang nk kena rename dgn nama apa,korang bukak file platform.ini yg diextract dr bersama dgn bios punya file tu.pastu cari:

[Platform_Check]
flag=2
PlatformName=361B
PlatformName2=3610

masukkan 361B and 3610 .BIN and .ROM

korang just masukkan .bin dan .rom dlm platform.ini.pastu file bios korang tu.rename ikot yg platforname tu.bukan platformname2.boleh la try ye.da yang da test, hasil nya, alhamdulillah jadi :)
