Win 7 was freshly installed on my laptop on a brand new 160 gb hard drive. 1st fresh install was Win Home ver 7 32bit. After installing 32 bit , realizied I mistakenly installed Win 7 32 bit Home version. Product key revealed original software was Win 7 Pro 64bit. Keyboard problem did not occur with 32 bit version. Once I installed the Pro 64 bit version the keyboard was non responsive.
Keyboard worked fine with 32 bit install and unresponsive after 64 bit install. Touch pad works.
I carefully removed and installed brand new laptop keyboard. Same identical problem. Non responsive laptop keyboard. Suspect this is a software problem but unable to know which/what software driver
may be compatible with 64bit Win 7Pro version. This was over a year ago and still there is no software (driver) fix for this. I am using a small keyboard on top of the laptop - Very Clumsy. I have hit a road block here and it has to have something to do with the changes described above. review Original install factory Vista. Then upgraded to Windows 7 64bit. After this I acquired this laptop working just fine, nothing was inoperative. Hard drive dies. I install new one and install win 32bit, discover the original software was Pro and then install 64bit win 7. After this, one by one I checked each and every update and driver. Everything available has been updated. Keyboard and Dell 1520 laptop's front edge media buttons, are inoperable as well as some function-key operations. I replaced Dell keyboard and no go. A friend tried upgrading bios and we saw the keyboard somewhat responsive for about 45sec then nothing thereafter. I welcome any practical ideas. I do not have an old version of Vista to start this all over again and I am reticent to allow a tech to mess with it as I am certain I would be paying through the nose for their education, catching up to where I am now. If there is such a service anyone can recommend which could perform this, I welcome it. Thanks alll
