Problem with Post-install PBI CE on HP Probook 4540s Yosemite

[ADLB]

Hi,
Happy New Year to you all
I have a Probook 4540s i3 who's working fine on OSX 10.9.5.
I bought another one for my daughter. I installed Yosemite on it, I followed the nguyenmac's method. Everything works fine.
So I try to do the same with my Probook by installing Yosemite on it.
I followed scrupulously the nguyenmac's method, everything goes fine until I restarted after the post-install with PBC CE 6.4.5.
Boot stop on black screen with the loading bar under the Apple Logo.
I tried several times but no way to a complete installation.
I need help please :/
Thank you very much

Make sure you install the latest IntelBacklight.kext. PBI has an old version.

After the success of installing Yosemite on my Probook 4540S, I decided to upgrade to El Capitan.
I used the Nguyenmac's method and everything is perfect.
El Capitan works fine !!!!
Hellyeah
Thanx for your precious help !!!

Please remember to fill out your profile/signature to include details on your ProBook...

Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)

Mobo: manufacturer/model + bootloader(Clover/Chameleon/Chimera)
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
Mobo: HP ProBook 4540s (Clover)
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.
