Apire E5-571-5552 touchpad does not work on power up

In this case, you can try reinstalling your touchpad drivers and see if that resolves the issue. You can do this by following the steps below:
1. Click "Start" and go to "My Computer" (or Computer). Click "Manage".
2. In the Computer Management window that comes up, go to "Device Manager" located on the left side of the window.
3. Click the + sign in front of "Mouse and other pointing devices".
4. Right-click the device listed below Mouse and other pointing devices and select "Uninstall".
5. Click "Ok". This will remove the device from your computer.
6. Now, restart your computer. Windows will automatically detect and install the drivers for your touchpad.

Hope this will help you.

You may need to check and delete any hidden devices that may be present in your computer. To do this, you can follow the steps below:
1. Go to Device Manager. To do this, you can follow the steps mentioned in the links below:
For Windows 7/ Vista:
http://windows.microsoft.com/en-in/windows/open-device-manager#1TC=windows-7
For Windows 8.1:
http://windows.microsoft.com/en-in/windows-8/where-is-device-manager
2. After you have opened Device Manager, click on "View" menu and click "Show Hidden Devices".
3. Now, from the list of devices displayed in Device Manager window, navigate to "Mice and other pointing devices" and expand the section by clicking +.
4. Now, uninstall one or more ghost/ hidden devices (if any) present under Mice and other pointing devices. If you are able to detect which all devices you are not using, you can uninstall them by right-clicking one device at a time and selecting "Uninstall". If you are not able to decide which of the listed devices are ghost/ hidden, one thing you can remember is that the icon of ghost/ hidden devices is lighter and transparent. If you find any such icons, you can uninstall the respective devices.

Once you have uninstalled the ghost devices, try reinstalling the touchpad drivers by following the steps mentioned in the previous post and see if that resolves the issue.

As the issue still persists, it is recommended to contact nearest Acer service center for further assistance. To do this, the following link can be useful:

I have also been having this issue since day one. Lost the receipt from best buy and dont want to give it to them for 3 weeks for them just to send it off to Acer anyways.

This is BS. Its a known issue......fix it Acer.

Never buying your products again.

You know what guys? As further proof Acer is ignoring this problem, all one has to do is google the sheer number of threads about this. There are countless, and googling 'Code 43 Touchpad' always provides tons of hits with, you guessed it, Acer.

They're ignoring this and it's clear they don't have a solution. If they did it would be front and center on this forum. It doesn't matter how many times you reinstall drivers, apply latest drivers, Elantech or Synaptics, or whatever, the driver will always corrupt when windows 8.1 goes into sleepmode.

C'mon Acer mods and techs.  Or God knows a solution.

Amen, brother. I'm convinced that there is no solution from Acer. What I see through these threads is that no Acer tech has responded with any sort of answer. I did find another thread for a different model Acer laptop where a user claims he found a fix: He reinstalled Windows 8.1 and installed all the drivers again in a specific order. Are consumers of a new laptop really expected to go through this to repair something that shouldn't be broken out of the box?

I suspect this:

The Acer 'reset' is to reuse their original image that sits on the recovery partition for the machine. Considering the amount of bloatware that comes with the laptop in order to reduce costs for Acer I wouldn't be surprised if this image is not corrupted or is loaded with the wrong drivers.

OR: 8.1 is not compatible with the hardware on these machines, namely the touchpad. Can anyone verify whether these touchpads have the same problem with Windows 7 or Windows 10 Eval?

OR: 8.1 sleep mode is not compatible with the Synaptic or Elan drivers. The only workaround I've found is to turn off sleep mode. The user has to turn off the laptop after use every time.  

Can ANYONE verify whether Windows 7 or 10 will work with these touchpads???

Hi all,

I got this laptop for christmas and found both Acer and Microsoft useless in dealing with the issue. So far I have discovered that a clean install does not work, changing the settings to stop the mouse sleeping helps but only sometimes and after having tried numerous drivers from Elan, Acer, Microsoft none work.

Microsoft have previously had an issue with an Acer (Elan) Precision Touch Pad and released a 'Hot Fix', but it won't install on our laptops.

I have also discovered (from others using a different operating systems (Lynux etc.)) that the issue may be related to the fact that more than one driver is needed to run the pad. One makes the pad work, another allows the pad to talk to Windows through a stupid bit of Intel chip architecture (I2C which was intended to be used in mobile phones). 

It seems that say the I2C drivers start up and say 'hey pad where are you' but the pad driver hasn't started yet so it gets no response and thinks "oh well it's failed to start... Code 43 time". Yet it hasn't failed to start, it just started a little to late.

This is proven by the fact that if you use the keys to navigate and restart the I2C driver it sees the pad driver that started late and works.

This is the work around I have been using as I have too much work on to send the **bleep** thing back.

A quick way to get it back up is to push the windows ket and X at the same time. Then use the arrow keys and enter to open 'Device Manager' and sellect the I2C HID driver > DISABLE IT and RESTART IT. Vowla your mouse returns... until it hibernates!

Acer, Intel, Elan, and or Microsoft can fix this with a bit of poking around in the software but form my experience none give a **bleep** about customer service, just shifting units and watching the bank ballene grow. I shall Acer time to develop a fix, then before the warranty runs out if a fix is not found I shall demand a new laptop, equivelent in function or better but different and without the problem. This is evidently a large scale issue and ACER need to wake up before they get an influx of returns in 9 months!
