Hello Client, I hope you are doing well. I’m an independent developer with solid hands-on hardware and Windows troubleshooting experience, especially when built-in input devices stop working after the OS boots. I’ll approach this Lenovo C940 issue by validating BIOS-to-Windows state, checking embedded controller/EC behavior, and ensuring the device drivers and power settings cooperate so the keyboard and trackpad work in Windows login, apps, and Device Manager. I’ll apply a concise, focused workflow and keep the fix hands-on within your 30-minute window. I have resolved similar cases by aligning BIOS, EC, and Windows driver stacks, then validating input responsiveness across boot stages. I’ll reproduce the issue in Windows, implement a targeted fix, and verify within a single sprint, with no external hardware required. I can handle this based on my expertise and past experience, keeping it simple, reliable, and durable. Best regards, Billy Bryan

Hi there, I see you're having trouble with the built-in keyboard and trackpad on your Lenovo C940, which seem to work fine in BIOS but fail to respond once Windows loads. It sounds like you've already done some solid troubleshooting, including a fresh Windows install and registry tweaks, so I appreciate the detailed context you've provided. I specialize in computer repair and troubleshooting, and I have experience resolving similar input issues on laptops. I understand the importance of having the keyboard and trackpad fully functional within that 30-minute window, and I’m confident I can diagnose and fix the problem effectively. For our remote session, I prefer using AnyDesk, as it’s user-friendly and efficient. My approach will be to first check device settings and drivers, then move on to software conflicts that might be causing the issue. I'll ensure that both the keyboard and trackpad work seamlessly in Windows before the time runs out. Just to clarify, are there any specific drivers or software you've installed that I should be aware of before we start? Looking forward to getting this resolved for you quickly! Best, Mubashir

I’ve handled Lenovo input issues where the keyboard and trackpad work in BIOS but fail in Windows, so I understand the urgency and troubleshooting constraints. Your requirement for a 30-minute live fix with no external devices is clear. I have experience resolving driver conflicts, registry quirks, and power-management settings that can disable internal inputs, using Quick Assist or AnyDesk for remote sessions. I focus on root-cause fixes so the keyboard and trackpad function reliably after reboot. We can schedule a quick session at your convenience to get this fully working within the 30-minute window.

Greetings, I am fully comfortable with your pay-on-success, 30-minute sprint arrangement. Since the keyboard and trackpad work in BIOS on your Lenovo Yoga C940-14IIL but fail once Windows loads (even after reinstall), this strongly points to a Windows-side driver stack issue — most likely USB/I2C, chipset, or HID service binding — not hardware. Within the 30-minute window, I will: • Inspect Device Manager (including hidden devices) • Verify HID/USB/Serial IO controller status • Remove corrupted driver instances • Manually reinstall correct chipset + USB/HID drivers • Validate required Windows services • Confirm proper driver binding • Test functionality before and after reboot I won’t repeat generic reinstall steps — we’ll target the root cause directly. I prefer AnyDesk. If all four acceptance criteria are met within 30 minutes, you release payment. If not, no charge — completely fair. Ready to connect when you are.

I’m comfortable working within the 30-minute pay-on-success arrangement and can connect via Quick Assist or AnyDesk for the live session. Since the built-in keyboard and trackpad are functional in BIOS, this strongly indicates a Windows-level driver, I2C HID interface, or ACPI configuration issue rather than hardware failure. During the session, I will focus on restoring the internal input devices by checking the Intel Serial IO, HID-compliant touchpad interface, and related system drivers/services, followed by applying the necessary corrections to ensure full functionality within the Windows login screen and desktop environment. I will also confirm the fix persists after a reboot performed by you before closing the session.

Hello, I’m comfortable with the 30-minute pay-on-success approach and can start immediately via Quick Assist or AnyDesk. This type of issue—where the keyboard and trackpad work in BIOS but not in Windows—is typically related to HID/I2C controller drivers, chipset/ACPI layers, or device enumeration conflicts. I regularly troubleshoot Windows input and device issues on laptops and can diagnose this quickly. I will verify functionality at login, in Windows, and after reboot to ensure the fix persists, with no external devices required. I’m confident we can restore full keyboard and trackpad operation within your time window. Best regards, Tarek
