Are 2002 Aztec computers compatible


I am assuming you are discussing the 2002 Pontiac Aztec, the early crossover with the rather distinctive look. I would assume that since they were made by the same manufacturer and they used the same parts that their computers should be compatible. I can't say so for certain as you haven't provided much information, but, unless one of the Aztec owner swapped out the original computer and replaced it with an updated device, the computers should be compatible.

If you are thinking of trying to swap computer chips, I would advise you to wait and let a professional do it at an independent shop. The reason I suggest this is simple, unless you know how to access the computer chip correctly, you risk accidentally ruining it. If you handle the replacement chip incorrectly it is entirely possible that for a stray static charge to ruin the chip by blowing out a trace. Also, if you damaged the socket from which the original chip was removed then it is possible that you will not be able to reinsert the new device without bending any leads on the bottom. If the leads are damaged, then the new computer won't work.

Even if the new computer chip and the original chip were already installed in installable cases (the way most desktop computer chips are installed), it is possible that when you removed the computer, you might have damaged the receiving socket which means that when you go to insert the new computer carrier it won't work correctly because a few or many of the pins on the bottom of the board won't sit correctly.

Why doesn't my HP 4620 print black ink


Either the BLACK INK CARTRIDGE is out of ink of it's possible the ink jets (they eject the ink onto the paper) are clogged/dirty. Your software under HP in PROGRAMS from the START MENU should provide a 'cleaning' cycle. How to Clean Print Heads is a link to help you with how.

Screeen is upside down


If you have a Windows OS, press and hold the ALT and CTRL (control) keys and then press the Up arrow. (If that doesn't work, try holding the Alt and CTRL keys and pressing the left (or right) arrow key twice.) If that fails, right click on the desktop (Windows+D will minimize all programs), anywhere with no running programs or icons. Then select the Screen Resolution option. Look for the line Orientation; use the drop down menu to select the correct orientation. Click Apply and then confirm the setting change if a confirmation window pops up. (This works in Windows 7 and 8.) For older Windows versions on laptops, you may need to select Graphics Properties (or a similar line) and then repeat this. The Windows screen rotation option is dependent on your video card. With some models, you'll need to open the graphics card properties to undo the rotation. You should see a line for the graphics adapter when you right click on the Display.

For Macintosh OS, make sure that the System Preferences is closed. Then open it by pressing Option/alt + CMD . Select the line Display. Find the button labeled Rotation: Standard then choose the correct screen orientation.

I hope this helps.

How do i reset my computer to an earlier date?


Most computers have a RTC or "real time clock" in the BIOS. BIOS (or "Basic Input Output System") controls how data gets into and out from the processor (via keyboard, disk, etc.). Be careful making changes. The BIOS is normally only accessable when the computer is powered on or reset, and then only while performing the POST (or "Power On Self Test"). At this time your screen may display text describing memory, drives, controllers, etc. Some machine have a "silent boot" enabled which displays a manufacturer's graphic or logo instead of this data. It is during this time the the BIOS may be accessed. Depending on the manufacturer of your computer, a key (Delete, Escape, F1 or some other) or key combination (ALT + F1, ALT + S, or some other) will be needed. It is required to press the key or key combination prior to the Operating System loading message(s). This can be done be repeatedly pressing the key (or key combination) once every second (or two) during the POST. Holding the key(s) down the entire time - or pressing them too often will result in an error, and require starting over again.

Once the BIOS screen is presented, you will have to scroll the entire page(s) to find the clock. Most BIOS brands have more than just a single page of settings. Using the the up, down, left, right, PgUp, PgDn & Enter keys - navigate to the clock hours and minutes and adjust as needed. Make sure that you SAVE changes before exiting the BIOS screen. Upon exit, the computer will reboot with your settings.

Your Operating System may also provide a way for you to change the system time (and date) as well. Try clicking on the time / date to see if it will bring up a dialog box that allows you to make the change.

I hope this helps and good luck! If my answer was helpful, please rate it "4 thumbs up" Thanks!
