Hey all — hoping someone with the same laptop can share an archived driver.

The machine: Razer Blade Pro 17" (2017), RZ09-01663E53, BIOS 02.00, i7-7820HK + GTX 1080, Windows 10 Pro 22H2 (build 19045). Out of warranty so Razer support won't take the ticket — they pointed me here.

Symptom: The Windows system tray is jumping ~2x per second because the TabletInputService is being toggled between "demand start" and "auto start" continuously. I confirmed via the System event log:

  • SCM event 7040 fires 10,255 times in 1h22m of uptime (~2/sec)
  • Starts 10.5 seconds after every boot — classic driver-init race
  • All events are on the TabletInputService start type
  • Win32k event 267 ("Touch HQA verification succeeded") fires at a similar rate, confirming the HID stack is being constantly re-probed

Root cause I've narrowed down to: the touchscreen device is enumerating against the generic Microsoft input.inf driver (v10.0.19041.3636) instead of a vendor ELAN driver. Windows reports "no pen or touch input is available for this display" — the touchscreen worked previously, but I did a clean Windows install in June 2023 and the ELAN driver never came back.

Device hardware IDs:

HID\VID_04F3&PID_2355&REV_1112&Col01HID\VID_04F3&PID_2355&Col01HID\VID_04F3&UP:000D_U:0004

What I've already tried — please don't suggest these:

  1. Razer's RZ09-01663 driver page (Answer ID 4590) — no touchscreen driver listed. The TOUCHPAD entry is Cirque_GlidePoint_4.2.0.2 (just the trackpad, not the touchscreen). Confirmed by extracting the package and grepping INF files.
  2. Intel Chipset and Intel Serial IO driver packages from the same page — no ELAN/VID_04F3 references inside.
  3. Windows Update → Optional updates — only shows an Acer monitor and a Samsung modem driver (unrelated).
  4. Microsoft Update Catalog — search by VID_04F3 PID_2355 returns zero, generic ELAN search returns Windows 11 fingerprint/touchpad drivers only.
  5. pnputil /enum-drivers — no vendor ELAN driver in the Windows DriverStore. Only input.inf (generic) and hidi2c.inf (generic).
  6. Razer KB Answer 1806 ("glitching touchscreen") steps — calibration is moot (touchscreen reports zero input), uninstall/reinstall just brings back the same generic driver.
  7. Currently on Synapse 3 (3.8.0630.062814). Synapse 2 was never installed on this OS image, so it never had a chance to deploy the original device pack.

What I'm asking: if you have a 2017 Blade Pro and your touchscreen is/was working, can you share the driver? Specifically I'm looking for whatever ELAN INF + .sys files map to hardware ID HID\VID_04F3&PID_2355. Pulling them from C:\Windows\System32\DriverStore\FileRepository\ if you see anything ELAN-named, or from a Synapse 2 install archive if you still have that.

Even an old Synapse 2 installer link would help — I can let it deploy the device pack itself.

Thanks in advance.
