HP Elitebook comparison


I thinking about buying a new notebook and since HP, Dell and other vendors released new notebooks based on Intel Sandy Bridge this would be the perfect time to replace my current MacBook Pro with a new Windows Laptop.

So basically I made this HP Elitebook comparison for all Important things for me based on the Swiss data. (In Switzerland not every model is available.) I also took always the best available option for me.

Maybe there are some mistakes in this chart but the most things should be right. And I don’t say one is better than the other one, clearly they are made for different tasks and workloads.

Other things:

  • I will add a Intel SSD
  • I will use 8GB RAM
  • I will not use an optical drive

What’s important for me:

  • I need long battery life up 6-8h (more would be better)
  • I need fast disk speed. Since I used a SSD I will never use a HDD again.
  • I don’t need a lot of graphic power
  • Resolution should be 1600×900 or higher
  • the notebook should be light and not to think
  • CPU power, should be enough to run Hyper-V for demos (boot from VHD)


Hyper-V Hotfix for Intel Sandy Bridge and Westmere

If you are using Microsoft Hyper-V with new Intel Sandy Bridge or Intel Westmere processors and our server has over 48GB of physical RAM you may get a performance decrease. Microsoft released a hotfix (KB2517329) for this problem.

This could also be a problem with a lot of Hyper-V installations on Cisco UCS, because the most of them will use more than 48GB of memory.

The performance decrease could show its self in the the following issues:

  • The CPU usage is high and the server responds slowly when you copy large files on the computer. For example, you copy a 10-GB file
  • The disk I/O performance of the virtual machines (VMs) is slow
  • Windows takes a long time to start

The hotfix is not include in Service Pack 1 for Hpyer-V R2 or Windows Server 2008 R2.

For more information about this you can check KB2517329
