My surface slim pen 2 doesn't seem to turn on - it is not charging despite putting it back in the charging case of the microsoft detachablekeyboard

I have tried long pressing the eraser button at the back, I have tried leaving it for longer periods in the charging slot in the keyboard, no matter what I do - it doesn't switch on, I don't see the white light blinking. And my surface pro is not able to detect it in the available bluetooth devices list for pairing either. So it basically looks completely dead - and I am clueless about how to bring it back to life. I don't think that this pen has any battery slot - so i am not sure what this means - do i need to replace it with a new pen, or is there hope left for the current one? It has been 2.5-3 years since i bought it, and i haven't been using the stylus lately -i guess i last used it 5-6 months ago. So not sure if that could be a reason. I also tried checking for updates- nothing there.

    Hi Rajeswari Parasa

    Have you had a chance to review the AI answer yet? It already covers the documented troubleshooting steps in detail.

    One additional question: does the keyboard itself appear to be charging the pen tray correctly? For example, does the keyboard work normally (typing, Fn/Caps Lock indicators, etc.) and, if available, have you been able to test the pen with another compatible charger or Surface keyboard?

    If the keyboard is functioning normally and the Slim Pen 2 still shows no LED activity whatsoever when docked or when holding the top button for 5-7 seconds, that strongly points to a failure of the pen itself rather than a Bluetooth, firmware, or Windows issue. After 2.5-3 years and several months of non-use, a failed internal rechargeable battery is a possibility. In that situation, replacement may be the most practical option.

    Based on the symptoms described (no LED at all, not charging in the keyboard tray, not visible in Bluetooth, and already checked for updates), the pen is very likely suffering a hardware failure rather than a simple pairing or update issue.

    For a Surface Slim Pen 2, the expected behavior is:

    • Amber (fading): low battery
    • White (fading): docked and charging
    • Amber + white (flashing): charging accessory needs an update
    • White (flashing): pairing mode
    • White (solid): successfully paired

    If there is no LED light indication at all, even after charging and checking updates, this matches the documented case where the pen needs to be replaced.

    Given what has already been tried:

    • Long-pressing the top button (pairing mode) – no LED
    • Leaving it in the keyboard charging slot for extended periods – no LED
    • Checking for updates – nothing available
    • Pen not appearing in Bluetooth

    Next steps:

    1. Confirm the keyboard is receiving power
      • Detach the Surface Pro Keyboard.
      • Shut down the Surface: Start > Power > Shut down.
      • Press and hold the power button for 20 seconds until the logo appears, keep holding until it appears again.
      • Reattach the keyboard.
      • Press Caps and Fn to confirm the keyboard is powered.
      • Place the pen in the keyboard’s storage tray and check for any LED activity.
      • If the keyboard itself is not receiving power, submit a service order for the keyboard.
    2. Try another charging accessory (if possible)
      • If available, try charging the pen with another compatible accessory such as a Surface Slim Pen Charger.
      • If the pen does not charge there either (no LED), the pen should be replaced.
      • If the pen charges on another accessory, the original keyboard/charging tray is likely at fault and should be serviced.
    3. If the pen still shows no LED and does not work
      • This matches the documented "no LED light (does not turn on)" condition. In that case, the pen needs replacement.
      • Go to Microsoft account | Select device for service and sign in.
      • Register the Surface device if needed, then select it and create a service order under Accessory → Pen issue types.
      • Replacement options will depend on warranty status. At 2.5–3 years, standard warranty is likely expired, but paid replacement or purchasing a new pen is still possible.

    If the warranty has expired, consider purchasing a new Surface Slim Pen 2 or compatible Surface Pen from the Microsoft Store or other retailers.
