HP Pavilion 15-e051se not starting after installing OSX Yosemite

Recommended Posts

Hi guys,
I have done a dozen Hackintoshes so far using Niresh Mavericks.
Today I have tried to install OSX Yosemite for the first time on an HP Pavilion 15-e051se.
I have Installed Yosemite and I was finishing the User Account creation steps. When I was a about to login to the desktop, it hanged. 
I have waited for around 10 minutes and then I shutdown the laptop by long pressing the power button.
After that, the laptop just won't turn on. Its sitting like a brick.
I have removed the battery and placed it again and still the result is same.
I will explain step by step what I did. 
Please tell me what happened.?
Hackintoshing Steps
* Created a bootable Yosemite USB using Transmac and Yosemite-Zone.dmg
* Created a bootable Windows 8.1 Pro USB using Novicorp WinToFlash
* Made some changes in BIOS
- Virtualization Enabled
- Legacy Boot enabled
- First Boot Option made USB and second Boot Option to HDD
* Booted using Yosemite USB
* Boot Flags used are
 /hp -v -f GraphicsEnabler=No PCIRootUID=1 UseKernelCache=No npci=0x2000
* Made 3 Partitions using Disk Utility
- YOSEMITE - Mac OS Extended (Journaled)
* Selected MBR instead of GUID Partion Table
* Restarted and booted using Windows 8.1 Pro USB and installed windows as usual
* Booted again using Yosemite USB
* Used " /hp -v -f GraphicsEnabler=No PCIRootUID=1 UseKernelCache=No npci=0x2000 " boot flags and selected the Yosemite usb installer
* Clicked "Customize" and unchecked "GraphicsEnabler=YES"
* Selected YOSEMITE Partition and installed Yosemite
* Selected location and did usual account creation steps
* After that I was asked to enter password on a login screen (But it was in Safe Mode, I saw the -x flag on top-right corner)
* When I entered password and hit enter, screen appeared to login (a gray activity indicator)
* After waiting for almost 10 minutes, I long pressed the power button and turned off the Laptop
* When I tried to turn it on..??? Nothing..!!! No LED indicators, nothing. Laptop is dead like a brick
* I can see LED indicator on charger port, so battery is working
* I removed the battery and put it back and tried again. Still not working
* I have also tried pressing power button for 30 seconds after removing battery and power supply.
* Then I connected the power supply and pressed the power button (No battery) and still no change
* Now I have removed the battery and I'm going to put it outside for an hour and retry after that
This is my problem. If any of you guys have encounted a problem like this, please let me know.

This exact same thing happens to me. I tried to install Hackintosh on my laptop of a similar model, and it done exactly the same thing as yours did. I'm sorry, to tell you, my friend, but I expect your laptop to never turn on again! My laptops motherboard fried after this, and is now broken. Nothing you can do to fix it, except get a new laptop. Sorry!

You can try, to remove the CMOS battery so that the BIOS checksum can be restored again. You have to find out how to do that for your laptop on the internet. It might help.

Good Luck
