Do I need a new motherboard for Windows 11? My laptop is Acer Aspire V7N-591G.

Hi guys, I'm having a dilemma. My PC is an Acer Aspire V7N-591G laptop. It meets all the requirements for upgrading to Windows 11 except for the TPM 2.0 chip. I'd thought about buying a TPM 2.0 chip (they're not very expensive) and manually installing it in the motherboard slot, but I don't know if my motherboard has the slot for it. It's an Acer Aspire VN7-591G V 1.13 Intel HM86 (Lynx Point) from 8/1/2015. Can anyone help me out?

If buying the chip doesn't solve the problem, I imagine the main option would be to buy a new motherboard. In this case, I imagine the problem would be solved.

Thanks in advance guys!

    Hi maliltokun205
    The Aspire VN7‑591G uses Intel’s HM86 chipset (4th‑gen Core) and was never produced with a discrete TPM 2.0 module or firmware support for one.

    • No drop‑in board exists — Acer’s parts catalog and resellers like Zandparts only list like‑for‑like replacements with the same chipset.
    • BIOS won’t initialize TPM 2.0 even if you soldered a chip in place.
    • Laptop soldering risk — far tighter PCB layout than a desktop, with high chance of trace/pad damage.
    • Economics don’t work — a full board swap (if it were possible) would cost more than the laptop’s current value.

    For Windows 11 compliance, the only practical options are enabling fTPM/PTT on a newer platform or moving to a system with native TPM 2.0 support. Anything else is high‑risk tinkering with no payoff.

    Ok, thanks for your answer. What about Windows 10 LTSC? Could that be a valid alternative?

    No, you likely don't need a new motherboard to upgrade to Windows 11. Most motherboards built within the last 5-10 years will support Windows 11, especially if they are already running Windows 10. The primary hardware requirement is a TPM 2.0 module, which is commonly found on modern motherboards. If your current motherboard meets the basic Windows 11 requirements, you should be able to upgrade without needing a new one.

    Here's a more detailed explanation:
    TPM 2.0:
    Windows 11 requires a TPM 2.0 module for security reasons. Most modern motherboards have this, but you might need to enable it in your BIOS settings.
    Compatibility:
    If your motherboard is relatively recent (within the last 5-10 years), it's likely compatible. You can check the manufacturer's website for specific compatibility information for your model.
    Upgrade vs. Clean Install:
    While you can upgrade your existing Windows 10 installation to Windows 11, a clean install is often recommended for a smoother experience, especially after a significant hardware change like a motherboard replacement.
    Licensing:
    Replacing the motherboard can trigger reactivation issues with your Windows license. You might need to reactivate Windows after the upgrade, but this is usually a straightforward process, especially if your license is linked to your Microsoft account.
