Need Help in Installing Windows 7 ?

[Kbharathkumar]

Hello  Everyone,  recent i bought an HP 15 -DY0004AU AMD Ryzen 3 Laptop

• 2200U processor, 2.5GHz base processor speed, 2 cores, 4MB L3 cache
• Operating System: Pre-loaded Windows 10 HOME
• Memory & Storage: 4GB DDR4 RAM with AMD Radeon Vega 3 Graphics | Storage: 1TB HDD
  

Now i want to install windows 7 by Removing Windows 10 Home Pre Installed.

i tried installing windows 7 Through USB and DVD and getting an Error " ACPI is not fully Compliant."

windows 7 ISO file used from the Microsoft Server and I have Valid Original Windows 7 Key.

legacy option is enalbed in BIOS.

i can handle the Drivers if Windows 7 is installed . So Drivers Problem is not  big deal for me even though officilay not supported.

Welcome to HP Forums,  

This is a great place to get support, find answers and tips,
Thank you for posting your query, I'll be more than glad to help you out 🙂

I see that you're wanting to downgrade the Windows operating system from Win 10 to Win 7, 
Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

Are you using Orginal windows 7 Operating system or retailer version?

NOTE: HP does not recommend upgrading or downgrading hardware parts or software that is bundled with the product as It may affect the manufacturer's warranty and performance, however, you could change the configuration at your own discretion.

While you respond to that, I recommend you to perform the following steps to isolate the issue and arrive at a fix:

Let's try this steps:

1. Go to Start, search for Device Manager, and open this result.

2. Expand batteries.

3. Right-click on the ACPI option (usually the 2nd option) and select delete or uninstall. Follow the prompts.

4. Shut down the computer. 

5. Disconnect the charger.

6. Remove the battery.

7. Hold down the power button for 1 minute.

8. Insert the battery only.

9. Attempt to turn the battery on.

Hope this helps! Keep me posted for further assistance.

Followed by clicking on "Accept as solution" from the drop-down menu on the upper right corner,

Thank you for posting in the HP Support Forum.  Have a great day!

Seems you haven't checked the System Model i mentioned and did a Blind Reply. The battery cannot be removed and it need to be handled by professional.

Thank you for posting back. 

I appreciate your efforts to try and resolve the issue. I apologise for the inconvenience caused, If it's a sealed battery you can just skip that part and continue to perform steps:

1. Go to Start, search for Device Manager, and open this result.

2. Expand batteries.

3. Right-click on the ACPI option (usually the 2nd option) and select delete or uninstall. Follow the prompts.

4. Shut down the computer. 

5. Disconnect the charger.

6. Hold down the power button for 1 minute.

7. Attempt to turn the battery on.

Keep me posted for further assistance.

Hi

Here's a daft idea.

Make a small partition, enough to take the OS and any HP drivers.

Copy the OS there.  Boot from a device and log to that drive and try the install from there.

Remember that W7 may prefer Legacy and not Secure Boot.

Sensible suggestion
