The battery on your HP Envy 14 Intel Core Ultra 7 155H shows plugged in but not charging, or the battery percentage is stuck at 80 percent and will not increase further despite the AC adapter being connected. HP Battery Health Manager charge limits and AC adapter verification resolve most battery charging issues on the HP Envy 14.
This guide covers HP Battery Health Manager settings, AC adapter verification, and battery driver troubleshooting for the HP Envy 14 Intel Core Ultra 7 155H in Windows 11.
“HP Envy 14 battery stuck at 80 percent despite being plugged in all day. HP Support Assistant showed Battery Health Manager was limiting charge to 80 percent to protect battery longevity. Switched to Full Charge mode before a travel day. Charged to 100 percent immediately.” – Masturah, project manager from Bangsar

Why Battery Does Not Charge on HP Envy 14
The HP Envy 14 Intel Core Ultra 7 155H includes HP Battery Health Manager – a feature that actively limits charging to 80 percent when Optimized Battery Health mode is selected. This intentional charging limit prevents the battery from spending extended time at 100 percent charge while plugged in at a desk, which accelerates lithium battery degradation. If the battery is at 80 percent and Optimized mode is active, the laptop shows Plugged in, not charging in the taskbar – this is expected behavior, not a fault. For travel or extended unplugged use, switching to Full Charge mode allows charging to 100 percent.
- HP Battery Health Manager set to Optimized Battery – intentional 80 percent charge limit
- AC adapter not HP-original or underpowered – laptop powers on AC but cannot charge battery
- Battery driver error in Device Manager preventing charge state communication
- Battery physically degraded – HP Battery check shows Needs Replacement status

Fix 1 – Check HP Battery Health Manager
Open HP Support Assistant. Go to My devices – Envy 14 – Battery section. Find Battery Health Manager settings. If set to Optimized Battery Health (80 percent limit), switch to Full Charge (100 percent limit) for travel use. Save the setting. The laptop begins charging from the current percentage toward 100 percent immediately after the setting change. Switch back to Optimized Battery Health for normal desk use where the laptop stays plugged in most of the day to preserve battery capacity over the battery’s lifetime. The HP Battery Health Manager charge limit is by far the most common cause of HP Envy 14 battery not charging past 80 percent.
Fix 2 – Verify AC Adapter Authenticity and Power
The HP Envy 14 Intel Core Ultra 7 155H requires an HP-original or HP-certified replacement AC adapter. Third-party adapters that do not communicate the HP Smart adapter ID via the center pin in the barrel connector cause the laptop to show AC Power Connected but show a warning that the adapter cannot charge the battery. HP uses adapter authentication to ensure battery charging is only enabled with adapters rated for the correct wattage. Check the AC adapter label for HP part number and wattage (90W or higher recommended for Core Ultra 7 155H) and ensure the adapter connector is fully seated in the HP Envy 14 charging port.
Run HP Battery Check in SupportAssist
Open HP Support Assistant and go to Hardware diagnostics or Battery. Run the Battery Check test. HP Battery Check measures the battery’s charge capacity (in Wh) and compares it to the design capacity. A battery showing Needs Replacement (below 80 percent of original capacity) will not accept charging at the original rate and may show Plugged in, not charging when the battery management system determines the battery is unable to safely accept charge current at the normal rate. Battery replacement under HP warranty or at HP authorized service resolves hardware-level battery charging failure confirmed by Battery Check.

Fix 3 – Update Battery Driver
Open Device Manager and expand Batteries. Microsoft ACPI-Compliant Control Method Battery and Microsoft AC Adapter should appear. If either shows a warning icon, right-click and select Update driver. If the battery driver shows error code 10, uninstall the device (do NOT delete driver software for battery), restart, and Windows automatically reinstalls the ACPI battery driver on next boot. Battery driver errors prevent correct charge state reporting from the battery hardware to Windows, causing the taskbar to show incorrect charging status even when the battery is physically charging or discharging correctly.
Fix 4 – Reset EC Battery State
Power off the HP Envy 14 completely. Disconnect the AC adapter. On some HP models, press and hold the power button for 15-20 seconds with AC disconnected to drain the embedded controller (EC) capacitor. Reconnect AC adapter. Power on. The EC battery state reset clears any stored charge state that may be preventing the battery from accepting charge. Some HP Envy 14 units develop stuck charge states after abrupt power interruptions where the battery management controller believes the battery is full when it is not, showing plugged in not charging despite the battery at lower capacity than full.
Frequently Asked Questions
