powerpower supply
I know for a computer I can change the BIOS settings to have it 'auto on'. This way the computer turns on by itself after power is restored ( instead of manually having to start the computer after power loss).
Is there a similar BIOS setting or a program which I Can use to auto restart a latop?
Thanks
I am asking this as a general question as we are planning to buy some cheap dell laptops. So I did not include the make and model.
For other users that are experiencing this issue, I thought I'd follow up with my own experience. I had the same problem, pushed the power button on the computer and nothing, no beep, no post, etc. After a few minutes the machine would magically turn on. This problem got worse and worse, and the delay before start longer. I replaced the CMOS battery and the problem persisted. I didn't suspect the power supply because the green led on the main board was lit and on. I was wrong. I replaced the power supply, and the machine starts right up again. This is a home build btw, and the power supply that failed was a 4 year old Thermaltake TR-2 600W ATX power supply.
Option #1:
In your bios you should have a 'power on by RTC' and 'Power on by pcie', have you tried disabling those? I believe they should be disabled by default.
Option #2:
Install and Configure a UPS Software
Step 1: Install PowerChute or similar software.
Step 2: Navigate to the Energy Management tab or similar within the Configuration setting.
Step 3: Check the Enable Energy Management checkbox and choose the Default settings in PowerChute. Look for any "Turn On Again" settings in any other power management software and check/uncheck as appropriate.
Option #3:
Option #4:
The .reg files below are for the registry key and value below.
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\CrashControl
AutoReboot DWORD
0 = Disable
1 = Enable
Option #5:
In command prompt enter the following:
wmic recoveros set AutoReboot = False

We have the same situation with a laptop in a remote location. We hook it up to a 2 hour UPS and when it quits during a power outage, the laptop battery is set to go to sleep mode when the battery reaches 50% discharge. In sleep mode, we find it will last for more than a day. A meaningless task is set to run every 24 hours, but only when AC power is on. This task can wake the computer. So, when power is restored to the laptop, the computer wakes up, within 24 hours.
