Another thing, is it provided with Optimus technology for switching between the 2 GPUs?

Guys, how come the official site said the battery up to 14:25 hrs, I expect about 10 hrs ofcourse not the all 14... and here in this review you say it is only 5 hrs??

Also another review on laptopmag.com say it is 7:48 hrs
Can anyone confirm?

My ZBook 15 with standard IPS LCD, i7-4800MQ, currently 67Wh battery. Left it to discharge at minimum brightness, ie: don't turn off LCD or sleep. It lasted a remarkable 13:35!! A 75Wh or 83Wh would exceed the quoted 14:25.

My configuration particulars:

- Win10 installed
- Hybrid graphics enabled in BIOS, ie: iGPU + Nvidia dGPU
- Power settings, maximum battery life for wifi, iGPU.

Key here is the SSD & it's configuration:
- AHCI mode set in BIOS, Intel RST driver installed
- Enable AHCI link power management via registry, set to "lowest", ie: DEVSLEEP
- Using Samsung SM871 SSD that supports DEVSLEEP
