You can download the manual from hpcalc.org or the HP website.

I would personally include photos of the screen during the test (e.g. "KBD OK").

Why is someone selling me 245/75/16 tires for a 2001 montero sport when that is not the recommended size

Not everyone knows about tires. They can say whatever they like, or sell you whatever they might want to sell. it is up to you to tell them that you want and is the required sized tires for your vehicle.
You can also go oversized tires for your vehicle if you like. As long as they do not rub any areas of the vehicle when installed. That could be dangerous.

Shop around for tires, you want to get the best you can get for the lowest available price. Don't be fooled by some numb nuts that doesn't know a car tire from a bicycle tire.

Why would Big Tex Air in Pflugerville charge $600/hour and sell me a used fan that was supposed to be new? It is also common practice for the general manager (Willie Ridgeway) to answer the office phone...

Hello
This is a fix it your self website.I would call the better buisness people and report him.
Also if you paid by check put a stop payment on the check.

I dont know, but i would take the used fan to Wille personally.Maybe he would be willing to make this right.

It is common to look for a leak in the attic.But you also need to check the entire system.

32-bit self-extractor module .exe file not working on USB

Self extracting exe files tend to run unzip once they start. It may be that the usb drive is getting full before it can unzip the files or it needs to run the files on c:. You are far better copying the file onto the target computer and running from there.

Memory stick

well, best buy usually doesn't sell memory sticks, its newer version is memorystick duo
the duo does come with a memorystick adapter
so, just go to any store that sells memory sticks such as bestbuy, walmart, target, etc, and you can buy one there
they should be $20-$50
