Hi Millie,
If the computer goes to sleep, alarms and timers might not work. Only newer laptops and tablets with a feature called
InstantGo can wake up from sleep to sound an alarm or timer. And even with
InstantGo, the device might not wake up if it isn’t plugged in.
Refer to InstantGo: a better way to sleep article for further
information.
Write to us for further assistance on any Windows related query, we will be happy to help you.
Thank you.
