  1. Power Light blinks before Shutting Down


    When I sign out of my user profile on my 2 Acer laptops and then click shut down, the computer goes black indicating that it is shutting down. However, the power light blinks until it shuts down completely. I don't know if it's a hardware issue or what but when hibernation is disabled, it tells you its shutting down and the power light doesn't blink (instead it shuts down normally). This is not a UEFI BIOS, it is a Legacy BIOS therefore it doesn't have the option to enable or to disable fast startup. This occurs on my Acer Aspire 5250 and Acer Aspire 5749 laptops. My Acer desktop doesn't do this, but it has a UEFI BIOS.

    Can anyone understand what I am saying?

    Also, if someone understands can they please help me with this issue?

    :)

  2. Battery problem not getting fully charged (Envy 15)

    My laptop get shut down while the battery icon shows 30% remaining( I have checked it out just before it get auto shut down) but when I press the power button light indicator shown "White light blinking i.e no power".

    And most important things are...

    1- When I am going to charge my laptop it doesn't 100% charged, it's just stuck on 99% charging, I have given it to at least an hour to 100% charge, but it is still stuck on 99% ( Battery indication is yellow light i.e charging).

    2- It is always shut down on 30% charging but when pressing the power button indication is "White light".

    3- Charging speed very fast up to 60% than usual( I have noticed it).

    I have been facing such problem for 2 month.

    It could also be the chipset driver. Although, I don't know what version chipset I have.

    Are you maybe doing Hybrid Shutdown ?
    Run this: %windir%\System32\shutdown.exe -s -f -t 00 or make a shortcut with that line in Target.

  6. CountMike, don't you have to have a UEFI BIOS to have Hybrid Shutdown?

    Looks like you don't. I don't have UEFI either and it works.

    Power Light blinks before Shutting Down

    I thought it was normal for the activity light to continue to blink until its actually off as its doing the shutdown sequence. Also you don't need to sign out before shutting down. Just one less step to do *Biggrin

    I thought the same thing. My PC does that.. red light blinks until it's fully shut down.

    It is normal and are you sure if it's power light instead of HD light is blinking. During shutdown, anything in cache would be written back to disk causing the disk activity light blinking. In addition, the system also kills all the background processes, unload DLL's etc...

    You can tweak the registry a little bit to speed up startup & shutdown.
    Code: Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon] "AutoRestartShell"=dword:00000001 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] "NoLowDiskSpaceChecks"=dword:00000001 "LinkResolveIgnoreLinkInfo"=dword:00000001 "NoResolveSearch"=dword:00000001 "NoResolveTrack"=dword:00000001 "NoInternetOpenWith"=dword:00000001 [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control] "WaitToKillServiceTimeout"="1000" [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer] "AlwaysUnloadDll"=dword:00000001 [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\Serialize] "Startupdelayinmsec"=dword:00000000 [HKEY_CURRENT_USER\Control Panel\Desktop] "ForegroundLockTimeout"=dword:00000000[/quote]

  11. Well my desktop doesn't do it. So, I figured it wasn't normal.

  12. Okay. That fixed it CountMike. Thanks for that suggestion. The only problem now is that when it boots up, it repeats the spinning circle sequence. Let me explain. When I turn it on, it has those spinning circles after the Acer splash screen. But, the spinning circle sequence repeats itself as if it is not ready to go to the lock screen yet.

    [/quote] Thanks topgundcp. I will try that to speed up the process. I have noticed a big performance decrease since upgrading my personal computer to Windows 10 which is the Acer Aspire 5250.

  14. Count Mike, after tweaking the registry like what topgundcp said to do. It somehow disabled the hybrid shutdown. I don't know. But when I put in what you said to do, it shut down normally.
