    As in the topic, maybe someone has already installed Windows 7 on this hardware.
    In addition to the two drivers, I managed to find and install the rest.

    One wanted is a graphics card (probably intel HD 620)
    PCI \ VEN_8086 & DEV_5916 & SUBSYS_16701043 & REV_02

    the second driver is a touchpad
    ACPI \ MSFT0101
    * MSFT0101

    If someone was working on the topic or could help, thank you in advance.

    Windows 7 does not support this feature.

    in bios I do not see the function of disabling intel ptt, is there anything else I can do?
    It's a pity to spend on one device like the rest of the device. it's working now.

    Turn off this device in Device Manager and don't worry.

    This is not a Touchpad driver.

    I've already got a little lost. because I do not have the option to disable intel ptt in bios, the touchpad does not work, right? and it won't or will work.

    ACPI \ MSFT0101
    * MSFT0101
    it is something else.

    I was just struggling with a similar model from Windows 7 for days.
    I checked all the possibilities, installed all the drivers, and I did not start the touchpad anyway, the function buttons from adjusting the sound level and from the touchpad switch do not work.
    As of today, the problem cannot be solved.

Topic summary

✨ The discussion revolves around the challenges faced by a user attempting to install Windows 7 on an Asus R541U laptop, specifically seeking drivers for Intel HD 620 graphics and a touchpad. The user has successfully installed most drivers but is struggling with the graphics card (identified by PCI IDs: VEN_8086 & DEV_5916) and the touchpad (ACPI ID: MSFT0101). Various responses indicate that Windows 7 may not support certain features, and disabling the internal pointing device in BIOS did not resolve the touchpad issue. Other users report similar difficulties, with no effective solutions provided for enabling the touchpad or function buttons related to sound and touchpad control.

FAQ

TL;DR: On Asus R541U with Windows 7, 0 successful touchpad fixes are confirmed; "As of today, the problem cannot be solved." Disable ACPI\MSFT0101 in Device Manager and source Intel HD 620 graphics separately. [Elektroda, DriverMSG, post #16795437]

Why it matters: It saves hours of trial-and-error by clarifying what works, what doesn’t, and the safest workarounds for Windows 7 installs on this laptop.

Quick Facts

Which drivers are missing on Asus R541U after a Windows 7 install?

The thread reports two missing items at first setup: Intel HD 620 graphics (PCI\VEN_8086&DEV_5916) and a touchpad-related request. That makes 2 initial gaps to close. Prioritize graphics, as the touchpad remains unresolved in later posts. [Elektroda, trolix, post #16794948]

What is ACPI\MSFT0101 on this laptop?

It is not the touchpad. It maps to a platform feature Windows 7 does not support on this model. The recommended action in the thread is to ignore or disable it rather than chase a driver that won’t load under Windows 7. [Elektroda, Kasek21, post #16795183]

Can I make the touchpad work on Windows 7 for the Asus R541U?

Users tested extensively. The touchpad did not start, and function keys for toggling it also failed. One expert noted, “As of today, the problem cannot be solved.” Treat the touchpad as unsupported under Windows 7 on this model. [Elektroda, DriverMSG, post #16795437]

Is ACPI\MSFT0101 actually the touchpad device?

No. A responder clarified directly: “This is not a Touchpad driver.” Don’t remove it expecting the touchpad to return. Focus instead on external input options or another OS if touchpad use is essential. [Elektroda, Kasek21, post #16795233]

Does disabling the “internal pointing device” in BIOS fix the touchpad?

No. A user disabled the internal pointing device in BIOS and the touchpad still did not work. Device Manager also showed no exclamation marks, indicating the issue isn’t a simple missing driver flag. This is a known dead end. [Elektroda, trolix, post #16795179]

I can’t find Intel PTT (TPM) in BIOS—now what?

One user reported no visible option to disable Intel PTT in BIOS on this model. If you lack the toggle, don’t keep hunting. Use Device Manager to disable the ACPI\MSFT0101 device and proceed with other drivers. [Elektroda, trolix, post #16795219]

How do I suppress the ACPI\MSFT0101 problem in Windows 7?

Quick How-To: 1. Open Device Manager. 2. Locate the device tied to ACPI\MSFT0101. 3. Right‑click and choose Disable. This silences the issue so you can continue configuring the system without chasing an unavailable Windows 7 driver. [Elektroda, Kasek21, post #16795221]

What about the Intel HD 620 graphics driver—any leads?

A helper shared a resource specifically after the PCI ID 8086:5916 was posted. Use that lead to obtain or guide the correct Intel HD 620 Windows 7 package for this device ID. Verify the PCI string before installing. [Elektroda, Kasek21, post #16795036]

Will the touchpad toggle (Fn) and volume keys work on Windows 7?

One tester reported the function keys for volume adjustment and the touchpad switch did not work under Windows 7 on this unit. This indicates broader hotkey support limitations alongside the touchpad issue. [Elektroda, DriverMSG, post #16795437]

Is there any confirmed fix in the thread for the touchpad on Windows 7?

No. The consensus report is negative. After days of attempts, the contributor concluded there was no working solution at the time of posting (Nov 2, 2017). Plan around this limitation. [Elektroda, DriverMSG, post #16795437]

What did moderators or power users advise when ACPI\MSFT0101 appears?

Advice was to disable the device in BIOS if possible, or simply disable it in Device Manager and stop worrying about it. This avoids wasting time on a nonfunctional Windows 7 path. [Elektroda, Kasek21, post #16795150]

If I uninstall devices linked to ACPI\MSFT0101, will my touchpad return?

No. One user even uninstalled the device but noted it’s hard to use the laptop without a touchpad, and the issue remained. Removing it does not restore touchpad operation on Windows 7. [Elektroda, trolix, post #16795229]

What are the exact hardware IDs mentioned for troubleshooting?

For graphics: PCI\VEN_8086&DEV_5916&SUBSYS_16701043&REV_02. For the platform device: ACPI\MSFT0101. Use these IDs to align any driver searches or to decide on disabling. [Elektroda, trolix, post #16794948]

Is the touchpad failure unique to one person or broader?

Multiple participants echoed the same outcome. Another experienced member linked a matching case stating the touchpad will not work, reinforcing it’s a model/OS mismatch rather than a one-off fault. [Elektroda, Kolobos, post #16795324]

What’s the fastest path to a usable system today?

Install other drivers you have, use the shared lead for Intel HD 620, and disable ACPI\MSFT0101 in Device Manager. Accept that the built-in touchpad and some Fn keys won’t function under Windows 7 on this model. [Elektroda, DriverMSG, post #16795437]
