SOURCE: touch pad quit working, fn-f7 doesn'make a difference

First, ensure that the button that enables/disables the touchpad is not deactivated if your unit has one.

If the keyboard still works, and you can navigate past your log-in password and enter your windows environment, here is a quick way to check and ensure your laptop still has the correct software driver for your touchpad mouse.

1: Press and hold your windows key, and press the R key.
2: This will open a run command prompt. Type "devmgmt.msc"
3: This will bring up your device manager. It contains all of the software drivers of your unit. If your mouse has a missing driver, it should boldly stand out from the list as an expended menu, within either your mouse drivers, or unknown drivers. You should see a yellow asterisk or exclamation mark next to the damaged or missing driver.
4: If the driver is missing, you can often re-download it from the manufacturers website and have the computer automatically re-install it once you have the driver saved onto your computer.

This solution is only for a single scenario though. Why your driver would have gone missing should it in fact be missing or damaged would still be questionable. It is possible that another program, such as a malicious spyware or virus, could have modified or deleted it. If that were the case, simply re-installing it would not erase the software that is causing damage from your machine.

This is only a software related fix. If it is hardware related, such as the touchpad hardware itself is defective or damaged, then it would need to be replaced by a certified technician, most likely at a service center. I would recommend taking it to your nearest Best Buy and having a Geeksquad agent inspect it, test a usb or ps2 mouse with it, and give you a better idea of which of the two possibilities (hardware or software) the fault is really being caused by.

Hope that helps.

SOURCE: Ihave an acer 9410Z laptop the backlight won't

Defective CCFL backlight, it may have the following symptom: Screen flashs on red/pink and off. Picture stays on in red and slowly be come normal. Picture flickering with dim display or appear black. Picture flickering on and off. All these symptoms indicate that the LCD backlight lamp (CCFL Lamp) has reached the end of the life and all you need to do is replacing the CCFL lamp.
Connect an external monitor to your laptop and power the monitor up first then the laptop, if you see the normal Windows images then the video card and laptop is OK and the problem is definitely the backlight. Dim image and/or dark display on the laptop's LCD screen indicates a faulty LCD backlight and it could be the inverter that supplies high voltage to the CCFL lamp or it is the CCLF lamp is nearly burnt out or burnt out, most likely this is the case.
The inverter can be replaced easily but the CCLF lamp is more time consuming and requires soldering skills.

SOURCE: Toggle Between Laptop and Monitor

Fn + F5 toggles the display output, the trick here to wait each time you hit this combination because it goes through several options. Hit it once and it may want to go to just the external, then both the laptop screen and the external. etc. Now Fn + F6 turns the backlight bulb off on the internal monitor to save energy. Now I am giving up the link to your service manual, it is in PDF format so you can make a copy for yourself and keep on the laptop, print it or save it to a flash so you can reference it later. I believe if you take the keyboard off and disconnect the video lead on the left side where the display plugs into the motherboard, then when you power the laptop back up it will default to the external cord and you can use the laptop without any switching. That is what I am doing with an Aspire 5920 that I am rebuilding. Good luck, ParrotHead PC Repair
Just copy and paste the link below to you internet address bar and hit enter.

SOURCE: hi i have a acer 5532-5535 laptop and the cursor

Make sure the button on the left side of the power button is not lit up. If it is, that will make the cursor stay frozen.

The touchpad is not working


Hi Asmorr,
Chances are, the touchpad was accidentally turned off.
Try pressing Fn, which is at the bottom of the keyboard near Ctrl and Alt, and F7 at the same time. This is the shortcut to enable/disable the touchpad on an Aspire One

The touchpad and scroll on my acer aspire 5734z does not work


It sounds like you've accidentally locked the touchpad. To unlock it hit the Fn key (lower left corner, between the CTRL and WIN buttons, it should be labeled with blue Fn label) and F7. That's Fn+F7, press and hold the Fn key, and then hit and release the F7 key, and then release the Fn key. On my Aspire this is the combination to toggle on and off the touchpad. It may be a different combination on your laptop but the rule of thumb is that you need the Fn key and one of the F1-F12 keys. The correct Function key will be labeled with a rectangle and a hand over it, illustrating a touchpad. Once you locate the key, press it and the Fn key as I explained above, and that should be it.

I've tried pressing fn and f7 at the same time and it won't work, neither will any of the other suggestions. And my computer keeps saying that the touchpad is enabled. Is there anything else that I can do...


Try hitting just the F7 key only. I had an issue with an HP Mini laptop and was hitting the Fn and the F7 key and found the key combination didn't work when I pressed both Fn and F7. But it did work when I just hit the F7 key (even though "F7" was written in blue, the same color as the Fn key, it turned out that I didn't need to press Fn and the key for F7 to gain the functionality of the F7 key. HP tech support informed me of that when I called them due to a similar issue I experienced a while back).

Try to hit F7 alone. That may help you out.

As for the touchpad, it should be enabled. (Unless you're using a different pointing device and want it disabled). There are options where you can turn off the touchpad on start up, but I would advise against doing so.

My touchpad mouse is not working


you can try pressing fn-f7 to turn it back on.. hold the fn key like a shift key, then tap f7 (it turns the touchpad on and off on the zg5 series units.) the icon looks like a touchpad with a finger.

Acer Aspire 5532 touchpad wont work at all. I had to use a usb mouse to be able to get online.


I just fixed this problem...the fn & f7 didnt work... at the top of computer where you turn the machine off and on - there is a button to the left. Press this button [not the on/off btn] and it should work.

Touchpad on my emachines g720 laptop will not work


Have you tried holding down the function key 'FN' ( next to ctrl at bottom left, and then pressing F7 ?

This toggles the touch pad on and off, so that when you are typing you do not move the mouse pointer around accidentally.
