The Microsoft ACPI-Compliant Systemis one of few HP laptops driver which never (most of time) installed automatically. Most of the time its make us wonder and thinking…what kind of driver it is. In most of HP laptop, you will find this dialogue after doing format reinstall. In some model, they will install automaticaly but some just don’t.
In my experient it is irritating when looking for driver. Because they didn’t say what we need to instal. They just wrote it down on their language. After format reinstal, we normally go to My Computer-> Manage-> Device Manager => check a yellow colour ? with dialog -> Unknown Device. When you double click on it, you will see what type of the driver you need and where is the locations.
If they said: the locations is – on Microsoft ACPI compliant system and the detail is – HPQ/0006 , if you go to HP Download drivers and software site..none of them wrote about it. But actually the driver is there only in different name. They put it under Driver – Keyboard, Mouse and Input Devices. Yes, it is Quick Launch button.
