Lenovo z500 - High memory usege+turn off the touch screen



I have Lenovo z500 Touch version.


My first question: Is there an option to turn off the touch screen? It takes a lot off battery and i rearly use it.


The second issue:

I have 8 GB of RAM memory, the constent state is about 45% memory use.

when I look at the task manager and I calculate the precentge of use by different processes and the amout of space they take in MB it looks like I have only 4 GB of memory.


For exemple, 800 MB use by the anti-virus is translated to almost 20%, somthing dosent end-up right.

I checked the hardware in Everset and in thesettings and they both showes 8GB

Re: High memory usege+turn off the touch screen

hi SolFine,


Welcome to the Forums.


There's no feature to turn OFF/ON the touchscreen but you can try to disable it via the Device Manager > Human Interface Devices (there are usually 2-3 entries here and one of them controls the Touchscreen > right click on it and choose disable)


As for the RAM usage, can you try open System Properties (Winkey+I > PC Info) and check the Installed RAM area,

If it says 8GB (4.xx usable), the RAM is most likely being allocated to the Integrated Graphics Processor.

Re: High memory usege+turn off the touch screen

It is unfortunate that there is no hotkey for disabling the touch function.  I have a practical reason for wanting such a feature : wiping off the screen while using the comutuer.  It is very frustrating to have to stare at a piece of dust or something on the screen because I don't want to mess up what I'm doing by touching the screen.  I hope the Lenovo developers fix this in future models.
