Can anyone help me out with this issue, it's driving me crazy!
I have a Sony Vaio VPCEB4X0E laptop running Windows 7 Home Premium 64-bit with AVG Internet Security 2012, MS Defender and MS Security Essentials. I have a standard user account with Administrator permission locked so that the password is required every time. I also have a separate Administrator account which I only use for installing new software and doing updates.
I usually leave the laptop to go to sleep then hibernate itself, or put it in to hibernate when I've finished using it at night. I close the screen lid and leave it (either plugged in or unplugged from mains).
At random times, I will notice that the fan has started running and I can hear HDD noise from the laptop. When I check it, the power light is green and when I open the screen it is on. If I log in and start Task Manager, I briefly see that the CPU is 30-50% busy on the Performance page (CPU Usage), but when I switch to the Processes page to see what is running and using the CPU, it goes straight back to idle. Laptop will be quite hot. I also wake up in the morning to find that the laptop is on.
I only ever use the laptop on WiFi to my home broadband, never wired LAN. Bluetooth is switched off all the time. This happens if I leave the WiFi switch on, or off - it doesn't matter.
I have tried checking through all of the settings I can find for Task Scheduler and have switched off all automatic checking and testing in all applications, programs and services (e.g. Defrag, disk clean-up, sync tools, etc.) that I can find, but this is still happening.
I keep AVG and MS anti-virus up to date and have run many full deep system scans with all checks switched on, but it's still happening. This is the first and only Windows 7 laptop that I have had and I have no other system to compare with. No one else that I talk to has this issue with their Windows 7 PC.
What I would like to know is:
1) What is making the laptop start up?
2) What process / program / service is running?
3) How do I stop it happening?
If I leave the laptop not connected to the mains power, it regularly runs the battery totally flat when left in Hibernate. When I try to use the laptop again, I can't switch on without mains power connected and then get the Windows black screen crash recovery screen due to total power loss!
Many thanks for any help!
Yours in frustration
