Lenovo ThinkBook 16 G6 IRL Slow Wake from Sleep Fix
Core i5-1335U
Sleep Fix
The Lenovo ThinkBook 16 G6 IRL (Core i5-1335U) should wake from sleep in under two seconds. If it takes 10 to 30 seconds or requires pressing the power button twice, the following settings and driver fixes resolve the delay in most cases.
Disable Hybrid Sleep
Open Control Panel → Power Options → Change plan settings → Change advanced power settings. Expand Sleep → Allow hybrid sleep and set it to Off. Hybrid sleep writes memory contents to disk before sleeping, which causes long wake times because Windows must verify whether to restore from disk or RAM.
Update the Intel chipset and ME firmware
Go to Lenovo Support, find the ThinkBook 16 G6 IRL, and download the latest Intel Chipset Device Software and Intel Management Engine firmware. Install both and restart. Outdated ME firmware causes the S3 sleep state to take longer to exit on Raptor Lake systems.
Update the BIOS
Install the latest BIOS from Lenovo Support via Lenovo System Update. Lenovo has released BIOS revisions for the ThinkBook 16 G6 that specifically address resume latency issues on the Core i5-1335U platform. This is one of the most effective fixes for slow wake behavior.
Disable Fast Startup
Go to Control Panel → Power Options → Choose what the power buttons do. Uncheck Turn on fast startup. Fast Startup uses a hybrid shutdown that can cause erratic wake behavior on ThinkBook models when combined with hybrid sleep.
Check wake timers in power settings
In advanced power settings, expand Sleep → Allow wake timers and set it to Disable. Background tasks that are set to wake the laptop (Windows Update, scheduled tasks) can sometimes trigger a partial wake cycle that interferes with normal sleep-to-wake transitions.
Ainul, Ipoh: “My ThinkBook 16 took over 20 seconds to wake from sleep. Disabling hybrid sleep and updating the BIOS through Lenovo System Update brought the wake time down to under two seconds.”
Frequently Asked Questions
What is the normal wake time from sleep for the ThinkBook 16 G6?
The ThinkBook 16 G6 IRL should wake from standard S3 sleep in one to two seconds when the correct drivers and BIOS are in place. Wake times exceeding five seconds indicate a configuration problem with sleep states or drivers.
What is the difference between S3 sleep and Modern Standby?
S3 sleep cuts power to most components and resumes in under two seconds. Modern Standby (S0ix) keeps the network adapter active and allows background tasks but uses more power. The ThinkBook 16 G6 IRL supports both modes depending on the BIOS configuration.
Why does the ThinkBook 16 require pressing the power button twice to wake?
This usually means the laptop entered hibernate rather than sleep, likely due to a low battery threshold or the sleep timer transitioning to hibernate. Check advanced power settings → Sleep after → Hibernate after and set Hibernate to never while plugged in.
Does disabling Fast Startup affect boot time?
On an NVMe SSD, the difference in cold boot time with Fast Startup off is typically under three seconds. The ThinkBook 16 G6 boots fast enough from NVMe that disabling Fast Startup is a worthwhile trade-off for reliable sleep behavior.
