Hi Rafa Zubimendi,
Thank you for posting the query on Microsoft Community and providing us an opportunity to assist you on this issue.
As per the query, it seems like the ‘Wake up’ on the Acer keyboard does not function properly on the computer.
I would like to gather little information on this issue to help you in a better way:
- What exactly happens when you try to use the Wakeup key on the keyboard?
- Did you try the wakeup key after putting the computer into sleep mode?
- Are you able to wake up the PC with mouse or other keys on the keyboard?
If there are keys particularly dedicated for sleep and waking up the PC on the computer and which aren't working, I would suggest you to contact the PC manufacturer for further assistance.
Please let us know if you have any other Windows related issue and we would be glad to help you.
