FAQ Modern Standby

All newer Dell laptops now use the Microsoft mandated Modern Standby. The old legacy Standby S3 is no longer supported. All newer Dell Laptops support Modern Standby S0 sleep only. The BIOS is written with this mandate in mind.

Travel safety and Laptops

With regards to transporting your laptop in a bag or backpack, safety should be your primary concern. You should always turn the laptop OFF =
* Select the Start button
* Click Power
* Click Shut down

In all extended travel and especially airplane travel, safety should be your primary concern. Under no circumstances should you leave a laptop powered on and in any sleep/hibernate/standby Network Connected mode when placed in a bag, backpack, or in an overhead bin. The laptop will overheat as a result of that action.

AC adapter is connected charging the laptop, you close the lid, it enters sleep. You then disconnect the AC adapter. The laptop remains in "Network Connected" mode. The result is you place it in your bag and it will still receive and install Windows Updates. Thus draining your battery and heating up in the bag.


Workaround 1 =
Before you close the Laptop lid, disconnect the AC adapter. This forces the Laptop into "Network Disconnected" Standby mode. Then close the Laptop lid. Now the Laptop is not able to receive and install Windows Updates.


Workaround 2 =
* Open Control Panel- Power Options- Change Plan Settings- Change advanced power settings
* Open the Network connectivity in Standby
* Change both On battery and Plugged in to Disable

Workaround 3 =
Turn the Laptop off prior to placing in bag.
