Specs: Windows XP
I have 2 hp550 laptops. From time to time, the displays will go blank like the back light is off, but you can still barely see the display and the pc is still running. Both laptops do this. I have reinstalled all of the hp drivers, and have scanned for malware. Any ideas?

"but you can still barely see the display"

That's an indication that the inverter is failing. It's a hardware problem. The inverter drives the light.

The inverter is in the monitor.
