this article refers to an issue in Acer notebooks and tablets recovery. After going through the whole recovery process, the system may hang on the last step, telling something like:
"Installing Cleanup (52/53)"
Note: that the numbers in the parentheses may differ depending on the model you are trying to recover
This really sucks a lot as you are already almost finished with the restoration, using the original recovery media, and still not able to use your device. The advice of the Acer service was to send the tablet (this happened to me with my Iconia W510 tablet [EN] [SK]) for (paid) servicing.
Easy solutions that do NOT work (for me):
- Simply pressing CTRL+ALT+DEL and requesting the Task manager does not help, as it simply does not show up
- Booting to safe mode does not help, as the system rejects it after reboot
- Booting a repair disk like Hiren's does not work because of the BIOS UEFI protection that I was not able to quickly override (my tablet does not support standard BIOS boot, no switch for that)
Very tricky solution that WORKS (for me):This is a very tricky solution. I hope it would work for you, but I cannot promise.
What you will need if you are working with a tablet (I am not sure with a notebook PC):
- USB mouse
- USB keyboard
- USB hub (preferably with external powering)
- USB optical drive (DVD)
- Your tablet
- Lots of patience
Note: you are doing everything on your own risk. Please be aware of that.
- Connect all the devices to the PC
- If your optical drive requires two USB connections, you can use an other PC for connecting the other USB port
- If you don't have the docking station (the keyboard), you need to use the microUSB to USB cable (you got one with your tablet)
- Nice guide is here
- Why? This will give you few seconds thanks to a system interrupt. Only a few, so be very fast with the next step
- This is tricky and took me lots of my nerves. You can do it easily - measure how long exactly the green screen lasts and do it on the very last seconds - or simply try again and again
- You probably won't be successful on the first try. Don't worry, neither was I. If it does not really help, kill anything that seems to run and does not need to run. You will see you were successful once the Cleanup screen does not show up after few seconds
- You can use this guide to do so
- You may also launch msconfig by pressing WIN + R, write "msconfig" and press Enter
- It might be also C:\Acer\Preload\Command\AlaunchX or somewhere else in the Windows, System, or System32 folder.. you will find it, I trust you
- wAlaunchX (so the full path would be C:\OEM\Preload\Command\wAlaunchX)
- WIN + R, type "PowerShell", press Enter
- Note: you paste by a right-click. The picture (and also the following one) is from Michael Pietroforte from 4sysops.com
- If it does not, press WIN + R, write "sysprep" and press Enter
