This may just be a simple software glitch, that a bios flash could cure. Go to Dell's support site and download the bios program or any updated bios. Also check for any patches that might clear this up. Dell is pretty good about keeping on top of little bug problems with their machines. If the bios flash doesn't work or if there is no patch , then the problem may be with the power management system on the motherboard. This is a common problem in many different machines. Let's hope the flash does the trick, but if it doesn't, then the problem will be a board component, and you will need to take it for a professional diagnostics in order to track down the exact problem.

    That's right, I forgot about that little Dell detail. Just a thought, check the battery connector in the machine to see if there is something in it, or if one of the contacts is out of place. It will have to see the battery to do the flash. Have you downloaded any patches, if not try this one. Also, I doubt that this will work, but have you tried a system restore.

    I'm going to say no. You're going to run right back into needing the battery as soon as you try the flash, but it couldn't hurt to try.

    Unfotunately, Dell doesn't offer the bootable disc option. I don't think you can jumper the battery connection, but you can try. I've never tried it.

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.

How to enable bluetooth


Your computer has to have a bluetooth radio. You can check
Control Panel > System and Security > Device Manager
Do you see a Bluetooth Radio listed?

If not, you don't have BlueTooth on your computer so you will have to add a BlueTooth device by plugging one into a USB port.

If you have a BlueTooth radio, go to Control Panel > Hardware and Sound > Device and Printers > Add a Bluetooth Device

This option is used to connect a blue tooth device (e.g. bluetooth headphons) to your laptop through your bluetooth radio.

See this Windows web page for more information.
Set up Bluetooth enabled device

I will respond to any additional questions you have.

How do I get the battery out of my acer laptop


Your Model of Aspire has a different battery release method, see attached pic on how to do it. This is a pic from your User Manual, you can download it from here Download Acer Aspire E1 572

. I suspect that the information you have been given regarding battery removal and passwords refers to removing the cmos battery as in a PC in the hope that it will clear Bios activated passwords.

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!
