We've had a customer drop off a HP Pavilion ZD7000 series laptop for repair. Symptoms include no backlight on the display, and corrupted video on the external and internal display both. Strange ansi type characters, etc.
It seems that this is a known issue on this series of laptop computer. In addition, even if the unit is out of warranty, HP will extend the warranty for this issue. We have contacted HP and arrange to ship the unit back to them for warranty repair. Since this unit is a Pavilion or Presario, the unit must go back to a central repair facility for this repair. If this had been a business series laptop, we could have repaired it here at the store. One more reason to look at the bit more expensive, but better service NC and NX series of laptops from HP/Compaq.
For those of you with the same model, and same problems, contact HP technical support directly, explain the situation, and keep after the technician until he finds the article on their knowledge base. My notes indicate that the ZD7000, ZD7200, ZD7300, NX9500, ZD7900, ZD7100 all have the same known issue. We can also facilitate this repair for you, but there will be a charge for the time needed for phone calls, packaging the unit, and testing the unit when it returns.

Epson Photo 2200 Printer Problems
At the store is a Epson Photo 2200 series printers, with a print quality problem. It isn't your typical cleaning/clog problem, and wanted to mention the issue here, and the resolution.
It seems that sometimes on the Photo 2200, the pump assembly while operating, doesn't do its job. The symptoms appear to be clogged nozzles, or colors that 'come and go.' After flushing and checking the colors that appear not to print, the technicians realized that the nozzles were clear, and it wasn't a clog or electrical problem causing the failure. After removing and examining the pump, it appears that the part would only work part time. In some cases you can rotate and operate the pump, but it wasn't really pumping anything. The resolution for this case is to replace the pump assembly. It is not a difficult repair, but in many cases, you would also want to clean your printer professionally, as this usually only happens after extended use of the printers, and as such, the printer could use a good cleaning and adjustment to ensure it continues to operate for a while longer.
Parts can be purchased from our store if you would like to repair this yourself, please contact a technician and they can help you determine which part you need.

Strange WinME Startup Program Issue
We're scratching our heads a bit at this particular problem, wondering if anyone out there has any experience with this particular issue.
It seems that on boot, on a older Windows ME installation, not all of the startup programs will run. In particular Norton Internet Security will just sometimes not start. No systray icon, nothing... If you start the Norton program, you will find that the firewall and antivirus auto-protect features are disabled. You can enable them, and work normally, but it takes you launching the application and telling the firewall/anti-virus to 'turn on.' There are no error messages during boot. My thoughts, ditch the ME since we all know that wasn't Microsoft's best day, but the customer dearly loves his system, so that's out!
Still working on this problem, so we'll update the article when we have a solution!
UPDATE: We were able to finally resolve this particular problem. In the end, it took completely uninstalling the product, including live update, and all other Symantec programs. Once the visible items in add/remove programs were removed, the technicians searched the directory structure and removed items such as the Symantec Shared directories,etc; the left over Norton folders in the Program Files directory, and cleared all user and system temp folders. Once this had been done, the program was reinstalled, and ran on startup, enabled, without any problems. We are elated that this problem was resolved, as the only other option was to reformat and start over from the beginning, which is a headache even for the seasoned users!

Xerox XC865
We have at the store a Xerox XC865 Workcenter unit which is prompting for a new fuser. After installing a new fuser, the unit continues to prompt for a new fuser. Check back soon to see what to do to resolve this error.
UPDATE: After further investigation, the unit did not have a fuser error, but a drum error message. I feel embarrassed I didn't catch this from the get go, but at the same time Xerox's user and service documentation is a little lacking. It seems that even after replacing a drum unit, you must manually enter a service mode on the unit and reset its counter. I could be wrong, and something may have gone wrong when the customer installed the new drum, but that is what was required for the unit to work without a flashing red light on the control panel. Once the counter was reset the unit worked fine without any errors.

Great source for diagnosing the error codes, or clearing some error messages.
