I had an ACPI problem with my Asus 1201n when it upgraded it to Windows 10 RTM. Here is what you can do: 1.- identify what kind of ACPI problem it is.

Rimage Prism 64 Bit Driver here. Aug 14, 2017. Asus Eee PC 1001HA Drivers Windows 7, XP 32bit: Asus Eee PC 1001HA have many features High Speed Processor, Graphics, RAM, Hard Disk Storage, Wireless, LAN, Bluetooth, Ethernet Ports, USB Ports, Built-in Speaker, Headphone Ports, Microphone Ports and more. This Portal has a big collection.

The way to do this is to launch task manager while the windows prompt for 'Asus ACPI driver is missing, Install ACPI driver' is on the screen. See the processes tab and check if in apps it appears the Hotkey service from asus and if in background processes you see it too along with the process for asus sender. If this is your case, then proceed to step 2.

2.- Uninstall Asus HotKey Service. It is ok, the only thing you will miss is the use of the key fn with asus specific functions on the top keys. But it will get rid of the prompt and the ram and cpu you are wasting on the glitch it is causing you. 3.- Restart once uninstalled. And that it is, it should be gone. Let me know how it goes. I have an ASUS Eee 1001PX Netbook (bought February 2011).

After upgrading from Windows 7 to Windows 10, I had the 'Missing ASUS ACPI Driver' error message. I followed the instructions. And downloaded and installed the ASUS Hotkey Service Driver, for an ASUS Eee PC 1225B After a reboot, the error message disappeared. I have just checked, and I HAVEN'T lost the use of the Function key.

I am very happy, thank you, TomsHardware.co. Freestyle Dash 2.2 Installer Download. uk. I'm not too sure if it will solve your problem, but here is what I did after reading about the 'hotkey' issues in this thread. I have an ASUS 1201n and was getting the 'Missing ASUS ACPI Driver' message after upgrading to Windows 10. First, I deleted the hotkey program. The message went away but I now had no Asus Fn function for the top shortcut keys.

I could live without those but I thought I would try another fix to see if I could get the 'Hotkeys' on the keyboard to work and get rid of the annoying ACPI message. I went to the ASUS support site and downloaded the Hotkey utility driver for an ASUS 1225B using the Windows 8.1 OS 32-bit option even though my computer is a 1201N originally with Windows 7. After installing the Windows 8.1 driver the missing ACPI driver message is gone and my hotkeys now work again in my upgraded Windows 10 1201N computer! Apparently the 8.1 Hotkey driver is what is compatible with Windows 10. If the 1225B driver doesn't work for your application, you may just have to try different ASUS model number hotkeys and see if you can get one to work for your particular computer. Just remember to pick the Windows 8.1 driver and not the Windows 7 one.

Hope this helps!
