usb 3.0 speed slow hp envy dv6 7215tx

Hey,

I have a Hp 7215tx, 

My issue is that i have a Brand new Patriot Supersonic Express usb 3.0 and a Kingston Data Traveler 3.0, Both of their write and read speeds are over 40Mbps but when i run them in my Laptop's usb 3.0 ports they start off around 21Mbps and then 10 seconds later drop to 7Mbps.

Yet when I use these same usb's on my  brother's asus or dell, they run at their full potential.

 

So is there something wrong with the ports or am i missing proper drivers.. I have kept my system upto date with Hp automatic updates.

 

Any help will be appreciated.

Thanx in advance

Hello gnmongia,

 

Your USB 3.0 ports are running slow.

 

Make sure you are using the port that has SS next to it, to be sure that you are using the 3.0 ports.

 

Go to HP.com and update the BIOS.

 

Also go to device manager and uninstall the USB ports and restart the computer.

This will uninstall and reinstall the drivers for the ports.

 

Here is a link to device manager.

Let me know how everything goes.

Have a good day.

gnmongia,

 

Go to power options and change the power settings to high performance.

 

Also go to advanced settings and USB settings and disable selective suspend setting.

 

  1. Go to your start screen 
  2. Type POWER.
  3. Click settings.
  4. Click power options.
  5. Click show additional plans.
  6. Select high performance.
  7. Click change plan settings.
  8. Click change advanced power settings.
  9. Double click USB settings
  10. Double click selective suspend setting
  11. Disable on battery and plugged in.

Let me know how everything goes.

Have a good day.

Re: usb 3.0 speed slow hp envy dv6 7215tx

thanx for your advice once again anothony, 

I tried exactly as you have suggested but to no success. I have also tried my USB on another computer with 3.0 port and it works better then it should so nothing wrong there.

But the problem still persists on my computer. It just starts off perfect and 4 seconds in just drops suddenly. 

I have also tried different sizes and types of files whilst transfering to no succes.

Any further help will be muchly appreciated otherwise any advice on whom i should speak to about this would be great.

regards
