Are P.O.S.T. Cards helpful?

My question is about BIOS beep codes. I regularly see computers both laptops and towers that don't POST. Once I've swapped RAM and disconnected peripherals it becomes difficult to narrow down if its the MoBo or the CPU. If it is the MoBo it would be nice to get a general idea of which component failed.

Seems more often that not I do not get an audible or visual beep code.

Would a P.O.S.T. Card be helpful here?

Post cards can not be used in laptop computers, I have purchased post cards but I found that they really do not help too much when I am troubleshooting. You have to figure out what the error code represents and sometimes it is not very accurate. I have not used post cards much at all over the past few years.

POST cards are helpful at times. I have one and use it from time to time to check unbootable PCs. Usually, it just confirms what I already know - mobo or CPU is kaput. The biggest drawback is that a POST card cannot definitely differentiate between a mobo and CPU failure. All that said, with the low current cost, a POST card is worth having. Once in a while, they can pinpoint a failure.
