Installing Windows on a HP Pavilion ze4500 Notebook

Posted in Geek Mode at Thursday, 15 September 2005 22:16 W. Europe Daylight Time

This week a friend of mine gave me his HP Pavilion ze4500 laptop to letting me install Windows and the common set of applications. His hard drive crashed after it was incredibly slow for some weeks. HP was nice enough to replace the drive.

However, I decided not to use HP's own recovery CD but a "real" (non-OEM) Windows installation I customized using nLite. Of course, there were not all notebook-specific drivers included in this package. The drivers for video, networking and modem were available through Windows Update and the HP support page, but Windows refused to gather drivers for the WLAN device in this machine (a Pavilion ze4526EA namely). HP's other support page doesn't show it as well and a Google search for the PCI Vendor ID/Device ID wasn't successful either. I had to call HP support to find the drivers for the LAN-Express 802.11b WLAN card (SP23038). The support people told me that there they built models with a LAN-Express card and a Broadcom card. However, the LAN-Express drivers are not listed on the support page (wheras the Broadcom drivers are on the English support page). That's not what I expect from a company like HP.

I encountered a unique issue that's somewhat similar to your encounter with not-quite generic drivers (and the inability to find them on HP's site -- and I unfortunately don't have the driver CDs):

After using an nlite-ened version of windows (with and without sp2) I experienced touchpad lags when attempting to move the mouse cursor, as well as keys on the keyboard that appear sticky (and this lappie is *very* clean, so no soda-stained messes bogging the keys down.)

I was wondering if you experienced a similar issue. I believe that it has to do with the built-in ps2 hardware for the keyboard and mouse and I just don't have the drivers to make it happen.

If you've found any fix (if you've stumbled across this problem), I'd appreciate a link ;)

sorry, I didn't encounter this kind of problems with the machine when setting it up. Therefore I'm not able to provide you with a fix to your problem. Another stange issue that appeared after I unplugged the notebook from the LAN cable: Windows boots directly into a BSOD. Disabling the network interface helps. However, I'm not sure why this problem occurs... The only solution might be to buy a new notebook, this time *not* from HP. But I'm not the decision-maker in this case since I don't own the machine.

Best regards,

I saw the sticky keys and mouse pointer lag problems on my ze4500 Pavillion notebook as well. This was before and after a clean install. I spent quite a bit of time trying to tweak the touchpad with no luck. The mouse lag and sticky keyboard keys make this virtually unuseable in my opinion! Seems like there should be an HP keyboard driver with the row of special keys but found none on HP's web site.. I suspect that this is some BS that they inherited from the Compaq merger and weren't too happy about having to support. It is a mess. I've shyed away from HP computers (from bad experiences with them when I was an IT mgr at a bank) all these years and now I know.. for good reason.

Not sure if I can post a comment here, but here's a try. I found this thread while troubleshooting a co-worker's ze4500 with the same symptoms. After installing the synaptics driver/utility with little improvement, I found the issue to be a bad battery. I know it sounds strange, but if you remove the battery it works fine. Hope that helps, -J
