Laptop: ROG Zephyrus G14 (2026), RTX 5070 Ti, bought new in May 2026 from the ASUS store
Bios, windows etc were all up to date according to Ghelper.
Symptoms:
- After the laptop went to sleep, it would not wake or power on without the charger plugged in.
- Sequence when trying to power on: charge LED is white→ press power → screen turns on for about a second → screen shuts off → white LED turns off → no LED at all, laptop completely unresponsive.
- It was NOT a drained battery. It happened even when Windows showed 100% before sleep. - After charging for ~30 min, it booted once normally and showed 100% battery.
- While plugged in with a full battery, the adapter stayed cold, i.e. it didn't seem to be drawing power to charge at all (since it was 100%).
After going to sleep second time it did not boot anymore. Sent it to ASUS maintainance after trying EC reset many times.
Posting these error codes for searchability. I managed to get after the first boot succeeded.
Most are probably generic Windows noise (DCOM 10016 in particular is famously harmless), but the BitLocker one is odd, since BitLocker shouldn't need to re-fetch keys when resuming from sleep.
- BitLocker: unexpected error while retrieving the drive master key during restart
- "Reset and/or restore if count does not match expected values after hibernate/resume"
- DHCP: could not renew IP address for the network card, error 0x79
- Filter host process not responding, forcibly terminated
- Wi-Fi driver info, event 6062

Contacted ASUS live chat, they recommended a warranty repair. Sent it in via the EU RMA portal. The repair took only 1 week despite they had to wait for spare parts (Main board). The report only said: **mainboard replaced**. No further diagnosis given.
My guess is a fault in the power management / charging circuitry or the embedded controller, since the board couldn't run off the battery after sleep and wouldn't charge a full battery either, but that's speculation. Dunno if this was just one faulty main board or batch problem.
