Question: Hello where does this go on an laptop motheboard. I know im not doing something right since i keep getting a FF error on every laptop.
Document: this thing does not work as intended. spits out the same code, FF, on every machine I've tried it on (working and broken PCs, no difference) and one of the LEDs is burned out (first digit, top left) so the code is not always clear. IF the code was clear it wouldn't make a difference because the included manual is gibberish, incomplete, and incomprehensible:"the card is named POST too. it could display the error code by the result of POST.
The card I got does not look like the picture of the card advertised. I don't have any "prev" or "next" buttons. It also came with the audio buzzer broken several of the resistors look burned out the diag LED's don't work and it gives the same error code no matter what I plug it into. Luckly I only paid $10 for the thing.I don't know if you can get this card from different sellers.
Everything everyone said about the card came true. It didnt fit right, the instructions are hard to follow. I'm a novice computer guy so I ended up breaking it. (dont put it in the wrong way) I bought a second one since I burned up the first.
A handy gadget to check your power supply. Works on both the IDE and SATA power cords. Hard to go wrong. Just plug it in and watch for all green lights and listen for a beep. Match the male and female ends before forcing. They only go together one way. If in doubt there are several You Tube demos as to how to use it. For the price you cannot go wrong.Keep one in your toolkit if you are a PC builder.
The unit didn't came up. It is either broken or completely incompatible with newer technology. Not sure if there is something better out there, but I wouldn't buy this if I were you..
Good afternoon, I am contacting you to ask them if I can send the motherboard manual for analyzing and motherboards to know the meaning of the codes. Plate with only cables I came. Or else tell me where I can download it or get it.Mucchas thanks.A greeting.Jose.
I was told that this works but not for everything he needed but I don't know what he needed. It did have a lot of functions and for the price is probably an okay product. You'd have to be in the field to know better than I. I am a woman in my 50s and I don't do diganostics on computers so my knowledge is limited. It seemed to be okay for some things and for this price, I think that's  okay
this product is helping my business out greatly. bringing more business to me and im thnkful. i luv the part
My pc stopped working out of nowhere. I removed every parts and plugged them in one by one, I still could not figure out what was wrong. I order the tester, and power supply tester (I thought the power supply went bad). As soon as I plugged it in, it gave a me a code and I was able to diagnose it within minutes.
Just about every bad review of this card centers on two items:1) Terrible, unusable instruction book, and2) Ham-fisted persons breaking the card or MoBo by tryingto stuff the card into the wrong slot.I can't help you with #2, but I did manage to find a great set of instructions in .PDF form for the use and operation of the card.
Answer: with compatible notebooks use the 25 pin parallel printer port (LPT) and USB port (for power) or desktop PCs using a standard PCI slot
