    lights fade out when PC's unplugged because of Capacitor Discharge . A capacitor is like a battery . It's designed to hold a specific charge for a particular lengh of time. when the capacitors are discharged , lights go out.

    I had the same problem. This can actually be an issue where there is no defect, just a condition where the computer is locked up. If you disconnect the power supply connectors from the motherboard, and the power supply light now stays on solid, try the following.
    Reconnect all connectors. Unplug power and wait for all lights to turn off. Take out the four screws on the back that hold the power supply in place and lift the power supply out where you'll have good access. Get a blow dryer and direct high heat throughout the power supply vents for a good 3-5 minutes. The power supply housing should be hot to the touch. Plug the power cord back in.
    If the power supply light is now on solid, let the power supply cool down and try turning the computer on.
    (If the power supply hasn't cooled down enough, you may see a temporary startup of all the fans and then the power supply light will completely turn off.) Unplug the power, Let it cool down more and try again.
    I would repeat this blow dryer process again, if you don't get the desired results the first time. If you don't get good results from this then you unfortunately have a real defect somwhere. Hope this helps. It worked for me.

If it is the power light on the front of the tower that slowly fades in and out, i've found that the most probable cause is some sort of hardware failure, such as with one tower i had, the DVD drive was faulty which causes it go into a sleep mode, sometimes removing the cmos battery can clear the problem, other times is where i remove the memory and turn the system on, it will beep because there's no memory installed, turn the system off again and let the system discharge of any power in it by unpluging the tower and press the power button, the power light will flash and go out, then replace the memory as long as you know the memory is good, that is thew way that i have found to reset the mother board and clear all faults.

The blinking button is an error code. You need to call HP and they will help you determine what the code means and how to fix the problem.

If Power supply light on or flashes
Perform the following steps, in order, until power is restored or it is determined that there is a hardware failure:
CAUTION: This product contains components that are easily damaged by ElectroStatic Discharge (ESD). To reduce the chance of ESD damage, work over a non-carpeted floor, use a static dissipative work surface (like a conductive foam pad), and wear an ESD wrist strap that is connected to a grounded surface, like the metal frame of a PC.

1. Disconnect everything from the computer, including the power cord.
2. With the power cord disconnected , press the power button on the front of the computer for five seconds. Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
NOTE: If the power supply fan makes an inconsistent grinding sound or stops and starts erratically, replace the power supply
3. With the power cord removed, flip the red voltage selector switch to the opposite position. Wait about five seconds, and then switch the red voltage selector switch back to its original location. Ensure that the voltage selector switch is on the correct setting, 115V for North America.
Performing this step ensures that the voltage switch is engaged and set correctly for your country/region.
Plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.
4. Plug a lamp into the same outlet to see if the wall outlet has power. Try the computer in a different outlet in order to eliminate the outlet as a possible source of the issue. Test both to see if the wall outlets have power.
5. Remove all extension cords, power strips, surge protectors and any converters that remove ground. Plug the power cable directly to the wall outlet. Test for power. If this fixes the issue, find the device that is causing the issue and do not use it.
NOTE: If you find the device that was causing the problem was a surge protector, resetting a breaker or fuse on the surge protector may fix the issue.
6. Remove all attached devices except for keyboard, mouse, and monitor.
7. Remove any internal component that was recently added, such as video card, memory, CD, DVD, and hard drives. An added device may take more power than the power supply is rated for. If the problem goes away when the component is removed, the only option is to upgrade the power supply to power supply with a higher wattage rating.

    1. Check the power switch:

    a. With the power cord disconnected, press the power button on the front of the PC. The button should release easily and not stick in the socket.

    · If the button sticks, it should be replaced or serviced.

    · If the power button does not stick and appears to be functioning, continue using these steps.

    b. With the power cord disconnected, remove the case or side panel.

    c. Follow the wires from the power button on the front of the computer to their connection on the motherboard.

    d. Look at the power switch cables connected to the motherboard. If the cable has become disconnected, connect the power switch cable connector to the connector on the motherboard.

    e. Replace the side panel, plug in the power cord and test to see if the computer can turn on. If not, continue using these steps.

    2. Find the defective part:

    a. With the power cord disconnected, remove the case or side panel.

    b. Disconnect all power cable connectors from their connectors on the motherboard and from the back of internal devices (the back of drives). Make sure to label or remember where each cable connects for future reference.

    c. Replace the side panel, plug in the power cord, and examine the light on the back of the power supply:

    · If the LED is on solid and is not flashing, the power supply is probably good and the problem is most likely caused by a defective component (processor, memory, PCI card) or a defective motherboard. Have the computer serviced, or remove the components and replace them, one at a time, to find and replace the defective component.

    · If the LED is still flashing (it should not flash with all connectors removed), plug the power cable into a different power outlet that is known to be good. If the LED still flashes, the power supply should be replaced.

    · If the LED light is now off, plug the power cable into a different power outlet that is known to be good. If the LED stays off, the power supply should be replaced.
    NOTE: If an electrical storm or power surge has recently occurred, then it is more likely that the power supply, the modem, or motherboard is damaged and requires replacement. If the power supply was damaged due to power outage or storm, this may not be covered under the "act of nature" policy in the warranty statement. Refer to the warranty statement that came with your computer for more information.

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

Removing bluetooth chip


Without knowing what the desktop computer motherboard is, I\'d only be guessing as to location of Wi-Fi chipset.
However even if I knew the motherboard manufacturer name, and model number; the point is Moot.

A) You remove that Wi-Fi chip, and kiss the motherboard goodbye.
It\'s designed into the circuitry of the motherboard.

Isn\'t going to be jumper wires taking it\'s place, and making connections to circuit traces on the motherboard.

B) Do you have a wireless router?
Dunno.
Do you have a wireless connection set up?
No.

You can use just a LAN connection. (Hard wired)

C) Suggest if having a Bluetooth option on your motherboard is not an option then use a different motherboard that doesn\'t have that option.

How to install Anti virus on my desktop


Following the steps to install antivirus on you pc.

Compare antivirus software. Look at the features and benefits of each. Read reviews from authoritative editors from magazines such as "PC World," "Smart Computing" and "PC Magazine." Editors who write for these magazines typically test antivirus software as an unbiased outsider and write about both the good and bad sides of antivirus software. For example, the editors at "PC World" recommended Avira AntiVir, Avast Antivirus and Panda Cloud Antivirus in an August 2009 article. Visit the websites of each antivirus program to view screen shots and descriptions of how the program works. Make a final decision about which antivirus program you want to install.

Navigate to the website of the antivirus program you've chosen. Go to the "Downloads" section of the site if you're obtaining a free antivirus software. Click on the "Purchase" section or "Buy" button if you have chosen licensed software; pay for and complete the transaction. Click the "Download" button or link for the antivirus program. Save the file to your computer desktop or to a computer directory or folder which you can easily remember.

Find the antivirus program file you downloaded on your computer. Double-click the ".exe" file (which is an executable file that will install the antivirus program). Once you double-click the ".exe" file, the installation process will automatically begin. Click "Continue" or "Next" on each screen to complete the installation process. Enter your name and contact details if registration is required. Follow any other on-screen prompts to complete the antivirus program installation. Restart your computer if necessary.

How do i turn my bluetooth on?acer aspire 5044wlmi


For Acep Aspire 504x model systems that have Bluetooth built in, there is an on/off switch located in the front of the system.

For systems with bluetooth built in there will be two buttons next to each other just left of the mic and headphone ports.

The left of the 2 buttons is the bluetooth switch and the right of the 2 buttons is for 802.11 wireless.

If you only have 1 button then you do not have bluetooth built-in. You can also check to see if bluetooth is included by looking at the bottom, if Bluetooth is installed there will be a white FCC lebel with the name Bluetooth written on it.
