My laptop with Win 8.1 Pro x64 has two issues with power states which are not working correcttly. They are:
1-the laptop does not shut down completely; either by navigating to the power down option on the settings charm bar or by pressing the power button on the laptop (I set it to shut down instead of sleeping as default). The computers apparently starts powering down, but the power led never switches off, and the cooler keeps spinning. It won't turn off until I press and hold the power button or the battery drains up.
Of course, the same applies to hybernating; the OS saves the content of RAM and starts shutting down, but never completely shuts down. Ditto with "fast boot" enabled; it doesn't matter if it's on or off, the laptop still doesn't power down.
2-if the laptop sleeps, it simply won't wake up. The monitor turns off and you'd expect to press a keyboard key or move or click a mouse button to awaken it, but nothing happens. Again, all I can do is holding the physical power button to force a shutdown or wait until the battery is drained. When the laptop keeps stuck in sleeping mode, I notice that after some instants the Num Lock led keeps lit, and won't turn off even if I press the key.
What do you think might be happening, is it some issue with ACPI or power states? What do you suggest to fix those issues? Thanks in advance.
