Coprocessor driver required

scbono · 03 Jan 2010

Hi, I have an AMD athlon 64 x2 dual-core TK-53 processor but i can't find an driver for the coprocessor not even on the offical site. Windows say's in the device manager that it isn't working properly because there are no drivers installed.
I am getting this message... The drivers for this device are not installed. (Code 28)
This is resulting in my laptop in crashing regularly and windows tries to recover the display driver.

I have a HP dv6525 with 7150M / nForce 630m - driver version 7.15.11.7948.
Running Win 7 Pro x32 bit.

Please help.

Hallo Scbono, It appears the only Windows7 driver/software HP has released for your model is the HP Wireless Assistant.
I did check all 6 different models as you didnt supply your full model number.
All i can suggest is to go to this site 24/7 Online support for HP's Home and Home Office Products - HP Customer Care (New Zealand - English)
and download the latest Vista drivers and use them.

Had this problem with a clean install of 7, reinstalled the latest chip set drivers and all was good.
Vista drivers should work try herehttp://h20180.www2.hp.com/apps/Lookup?h_lang=en&h_cc=us&cc=us&h_page=hpcom〈=en&h_client=S-A-R163-1&h_pagetype=s-002&h_query=HP+dv6525&submit.x=9&submit.y=7

Welcome to seven forums scbono.Just as a teaching aid. When ever you start or use a thread, scroll to the bottom and you will see a number of threads on the issue in common as well as the use of the search function. This coprocessor problem has numerous threads with some resolved others not. It's worth the research. best wishes . Also with these HP notebooks they have several different model numbers like yours ending in ea,ei,em,en,eo or tx this may designate special upgrades ect might need to know. You can usualy fix a coprocessor problem with updating the chipset drivers. No 7 drivers avalible but a bunch of Vista some listed as critical These are for the DV6525ea Select software and drivers HP Pavilion dv6525ea Entertainment Notebook PC - HP Customer Care (United States - English) You'll have to use compatibility mode to update compatibility mode Compatibility Mode.
