20 Most Recent Acer Aspire 5742 Notebook Questions & Answers


If you hear a quick click of the dvd/cd unit, and the reboot sequence restarts all over again, endlessly. Most likely this solution will work for you.
1 Unplug the power.
2 Flip the laptop over.
3 Slid the "lock" for the battery so you see red (or the battery is in unlock).
4 Push the other slider mechanism to remove the battery, and slip the battery out of its holder.
5 Take a small Phillips head screw driver and remove the screw in the middle of the back of the laptop.
6 Slide the DVD/CD player out from the side of the laptop.
7 Complete the battery reinstall in reverse steps, plug in the A/C adapter.
7 Power up the laptop.
! Viola - No more boot loop issue.
Now you need a new DVD/CD unit (or you can try to put it back in, sometimes they start working due to a poor connection).
Why? The DVD/CD player in this laptop is a convenient place to pick the laptop up. It gets jostled around a lot. There's also a lot of heat generated right near the units. They also have poor hold down and connections as you will witness, once removed. It is a part of the boot process to check its operation, no work, no boot, it doesn't communicate well either. So it just keeps rebooting not telling you why. Since the player doesn't work, you can't use your recovery discs, lol.

If machine not booting it could be a bad cmos, hard drive, mo bo, peripheral, corrupted OS, bad power supply, bad memory,
Remove the hard drive and see if it posts and then gives you message that there no boot drive If that does not happen then machine is not even posting which means something is wrong with the cmos. - not a good thing.

are you on about the mouse you use on the laptop or a mouse you have added?

Overheating When the CPU overheats then it will shut down (i.e. thermal overload) and won't boot up again until it has cooled down. If this is the problem is not fixed then the CPU will eventually fail.
A faulty fan causes the problem or the fan and heat sink assembly are clogged with dust.
Check the CPU fan to see if it spins freely, if not replace the fan.
If the fan and heat sink is clogged with dust the remove the dust and make sure the vents are clear and dust free. Use a small brush and can of compressed air to do this.

Hello,

Thank you for using fixya. My name is Carlo.

There are two ways that you can do to turn off/on the touch pad in your acer aspire.

1. Press FN + F7. It will turn off the touchpad and will turn on once you press the same buttons again.

2. If the buttons do not work. You can do this:

1. Go to control panel>hardware and devices>Devices and Printers>Mouse
2. CLick on the last setting on the right.
3. Click on Disable in the Mouse Properties.
5. Click OK.


Just go to the same area when you want to enable your touchpad again.

I hope this helps.

Carlo

Could be the cmos battery low voltage, the processor may be too hot, the video firmware may have errors ... could be all manner of things.
Try updating your drivers after checking the cmos battery.

If your computer is asking for a bootable disk drive on startup, it typically indicates drive failure and your harddrive needs replacement. Sorry for the badnews.

Could be almost anything but does it charge the battery? If it does in may be a processor issue if not there is a power supply issue on the main board. Without detailed information, it will not be possible for you to pin point a faulty component as the main board uses DC-DC convertors and one may have stopped oscillating..
