How do i use Sata 6gb/sn port on Intel HM76 Mobo in HP Pro.4540s

I don't know if you have sata 3 or 6 GB/s ports on the notebook. If you do there may be an option in your BIOS to switch. But, either way, the Vertex 4 will work fine in the notebook. It is backward compatible, meaning it will work on sata 3GB/s or sata 6GB/s ports.

I just bought a HP 4540S a few days ago.

Mine has the Hitachi HDD same as yours. Mine came from the factory with the Bios set to SATA 6.0Gbs and AHCI mode.
You can go into Bios and make sure the SATA 6.0Gbs button and AHCI button are selected.
This is a very simple Bios and has very few options.

When the laptop boots to first HP screen keep pressing ESC (escape button).
This will give you options to navigate.
Below is a SNIP of the manual for our laptop. How to get to where you need. You still may need to do a little searching once in.
I found it quite easily.
Hope this helps.

I suspected my HDD is SATA 3.0 Gbs. It will work on Sata 3.0 or Sata 6.0 mode.
It can only work at Sata 3.0 speeds as that is what it was designed to do.

The Vertex 4 will be a nice addition to your laptop.

I ordered a Samsung 840 250GB for mine. It should arrive today.
Good luck.
Post again if you need more assistance.

Yes, sata 6.0gbs choosed in bios. But hdd is not working on 6.0gbs mode. Maybe hdd isnt support 6gbs. I hope it will fine with ssd.

afaik, HDDs don't even saturate 3.0 Ggbps (or SATA II) due to mechanical limitations.
Most laptops don't mount SATA III hdds for cost reasons even if their sata ports could do it. Also because you won't notice the difference. SATA III is mainly for SSDs.

Your welcome.
Excellent numbers.

My SSD won't be here until Monday. It missed the Saturday mail.

My new Ram arrvived. Going from 4GB to 2x4GB made a big improvment.

I hope my new SSD does as well as yours.
Enjoy!!!

Nice scores, RIDVANBAL. Well done. Those are some really good numbers.
