Acer laptop stuck on Windows boot manager


1. Restart the Acer Aspire netbook by pressing the "power" button on the netbook's keyboard or by pressing the "CTRL," "ALT" and "DEL" keys at the same time.
2. During startup, hold down the "F8" function key immediately when you see the "Acer" splash screen and the option for entering "Setup."

3. Keep pressing the "F8" key until the "Advanced Boot Options" menu appears.
If you receive a "keyboard error," restart the Acer Aspire and repeat step 2.

4. Use the arrow keys to navigate to the "Safe Mode" selection on the "Advanced Boot Options" menu.
The arrow keys are located on the right-hand side of the Acer Aspire keyboard.

5. Press the "Enter" key to execute the "Safe Mode" selection.
The Windows operating system will now start in "Safe Mode" and you can perform a system restore or make needed changes to get your Acer Aspire to boot normally again.

Unable to detect any wifi when I know my wifi network is on, working, running, just fine! The other laptop in this has is getting wifi perfectly, so is my Android phone.. I tried downloading the wifi...


If it is three days old and no wifi you may not want to read this...;-]

There is a off on switch for the wifi either in front or along the side of the case. By default it is off. The wifi will show installed and working but won;t do anything. The hard part is finding that stupid switch. Followed by pretending you knew it was the problem all along. I'm chuckling at this as everyone myself included has done this. If it is anything other than the switch on a 3 day old laptop I'd put in in the box and return it.

it's the switch ;-]

My acer aspire 5742Z touchpad is too sensitive or I don't really know how to use it. Every time I touch it something stupid happens on screen. Now it has turned my screen dispay side on and I have to use...


Definitely your touchpad is TOO SENSITIVE!
To modify the sensitivity just go
START > CONTROL PANEL > MOUSE/TOUCHPAD and adjust there the sensitivity by dragging the cursor to the LEFT until it reaches the middle.
In PROPERTIES just re-invert the functions of your touchpad to get rid of the mixed axes.

Try uninstalling and reinstalling the video drivers. If this doesn't work, it's likely that the LCD control board or cable is damaged.
