"Testing and repairing computers is a difficult task that is often made more difficult by unwieldy diagnostic tools. Manually running diagnostics and burn-ins is a burden on personnel resources. Ultra-X's QuickCAST D.D.R. Mobile Diagnostic Deployment Appliance provides an automated diagnostic tool that is simple to deploy and requires almost zero maintenance, all in a form factor about the size of a smartphone."

And if you think the RAM "test" your motherboard performs when you boot the machine is enough to catch all the errors, think again. The R.S.T. Pro2 slips into a PCI slot and works the RAM over like Rosie O'Donnell at an all-you-can-eat buffet. It's superior to a stand-alone RAM tester because the RST Pro2 tests the RAM in it's natural habitat- the motherboard. You can also use the R.S.T. Pro2 to test the integrity of the BIOS's memory timings.

"Even better than Memtest 86 is Ultra-X's RAM Stress Test Pro2, which is a self-booting diagnostic plug-in card. This card uses a comprehensive set of test patterns to assess your memory, and we've found that it finds bad pieces of RAM that other testers miss."

Needless to say, using such a device to diagnose laptop hardware glitches would save both time and money. "
