Asus ux305 sleep standby time

Asus UX305 has been good at maintaining a long standby time under sleep/hibernate mode. 2 Weeks standby time was marketed.

Thus i find it weird when i close my lid my battery went down from 95% to 5% after coming back in 12 hours. This problem didn't exist before, and im thinking its a certain app/program/activity that is draining my battery during sleep. Any ideas guy?

 

How long have you owned this notebook?
If it goes into sleep/hibernate mode then no app/program is running anyway.
Fully charge the battery, and test its battery time until it's drained to see how long it can provide you.

 

I have had it since April. Usually on sleep mode it would rarely run out of battery even after a few days. I'm suspecting now that when I close the lid, it doesn't go into sleep because certain programs prevent it from doing that, instead only the monitor display is turned off.

 

Check the status LED and please verify.
If it's blinking then it's sleep, but if it's off, then it's either a straight powered off, or powered off after hibernation.

 

Asus UX303 has a design flaw and Asus UX305 may have similar.

If you put UX303 to sleep and it is not connected to the charger, then it will be waking up every few hours, thus discharging battery.

You may see this on this video:


You may check in Windows logs if computer is waking up. Let me know if this happens.

 

Did you check in the power management options in the control panel, to make sure it is set to go to sleep? Check to see if Allow Wake Timers is disabled or enabled in the advanced settings. I would also check to see if there is any programs running in the background, like if you have any kind of backup or automated tasks that could be doing it.

 

Man... didn't you read? This is brand new computer, directly from the shop. Absolutely nothing installed. I've seen same problem with two other brand new Asus computers. Asus service replaced motherboard and some other components and problem persisted. If problem persists after motherboard replacement then most probably this is design fault of the model or even entire product line, as it exists in more than one model.

 

Check under advanced power settings and look for hybrid sleep, then verify whether it is on or off.

 

Hybrid sleep is for desktop computers, not for laptops. When it is enabled, during going to sleep computer writes it's entire memory to file on disk (so it is actually more like a hibernation).

This is a safety measure in case of power loss. Such power loss would cause loss of unsaved data in desktop computer, which doesn't have battery.

Enabling this option makes sleeping computer a lengthy process, especially when there is lots of memory to be written (e.g. when computer has 16GB of RAM).

"Hybrid sleep is designed primarily for desktop computers"

 

I know, but the behavior your notebook acted is similar to hybrid sleep that's why I was wondering why.
What if you do powercfg -hibernate off?

 

IIRC the hybrid sleep was disabled as it came from the shop. I've returned this computer so I can't test this.
