Windows 7: Powerdown after shutdown not happening (batt drain when off)

Powerdown after shutdown not happening (batt drain when off)

Hi sorry about his probably familiar type of first post from a non expert who badly needs some help.I have just been given a Fujitsu Lifebook S6540 running windows 7 and on the whole it is fine but it is eating the battery when switched off. Research on the internet has shown that the computer, although seeming to shut down may still be running in the background. I have therefore been into the registry and changed the powerdown after shutdown code to 1 rather than 0 which should ensure a complete shut down. I duly did this and let the computer charge up before shutting down and then left it for a day. It did not make a shred of difference and found half the battery had been used.

I have read around on various things that might cause this but a lot of it has been in extremely technical computer speak that I have been unable to understand. Is anyone here able to give me some clear trouble shooting advice and tell me what may be causing this?I would be very grateful. I am currently leaving the computer for a while after opening up in safe mode then shutting off

How are you shutting down? From a the desktop hit Alt+F4, make sure Shut down is selected then hit the enter key.

you could also turn off the hibernate system, Cmd prompt, powercfg -h off hit the enter key. Once that is off the system may shut all the way down.

If the battery is at half a charge in that short period of time, my first question is; was the computer used? If so, the battery charge does not have the same storage time capability as when it was new and will be reduced more rapidly.

It could also be some type of BIOS setting keeping something like the NIC and wireless NIC active for Wake On LAN function.

If it was a bad, old or faulty battery the OP would notice a very reduced run time while the system is running and not connected to AC. He never said the battery doesn't last long when he is using the computer and not connected to an AC outlet. But that it loses its charge when powered down.

So, do you believe that the computer is somehow consuming more battery power when the OS has been shutdown and the computer is placed in any of the available power modes; sleep, hibernate or complete shutdown? I don't see the connection. It seems more likely to me that there would be a higher usage while running the OS. I am certainly not an electrical engineer, but that was how I looked at it.

That's just it. The OP doesn't feel the computer is shutting down all the way. Never heard of this on any other notebook.
I do know that Windows 8 has this feature where the system really doesn't shut down. It goes into some type of hibernation.

Personally I have a Macbook Pro and a Dell E6420 and when I shut those systems down they both power completely off. If the battery level on either is at 50% when shutting down the next time I turn them on the battery is still at 50% or very close to it, like 48-49%. But certainly not like what the OP is seeing. But then I do not Sleep or hibernate any of my computers.

That was why I asked the OP "How are you shutting the system down". If he is using the power button then it very well may be putting the system into sleep or hibernate. Instead of doing a REAL Shut Down.

As with many poster to this forum he has not replied back with any answers to questions.

I believe we are having a problem in our communication. However, as you state the OP hasn't replied so who knows what may be causing the problem.
