Hilo سلام دوستان وقت همتون بخیر باشه

ببین این دو حالت داره یا بایوسته که بعد از این که از باتری در میاری میبره رو سیو مود باتری یا باید چک کنی توی تنظیماتت که نره روی سیو مود، منم قبلا این مشکلو داشتم ولی تا جایی که یادم میاد ی پارامتر کرنل بود که اونو توی رانتایم میزدی اوکی میشد

### 🔍 Probable Causes - CPU Frequency Scaling on Battery Ubuntu (and many Linux distros) often throttle CPU performance when unplugged to conserve power. This can cause noticeable slowdowns if not properly configured. - Power Profile Misconfiguration The system might be defaulting to an aggressive power-saving mode (like power-saver) that limits performance drastically. - GPU Driver Behavior If you're using a hybrid graphics setup (e.g., Intel + NVIDIA), the switch to battery might trigger a fallback or inefficient GPU mode. - TLP or PowerTOP Conflicts These power management tools can sometimes apply overly aggressive settings when switching to battery, especially if not tuned. - ACPI or BIOS/UEFI Quirks Some laptops have firmware-level power management that doesn’t play nicely with Linux, causing erratic behavior when unplugged. --- ### 🛠 How to Fix It Here’s a step-by-step approach to diagnose and resolve the issue: #### 1. Check CPU Scaling Behavior Run this command on battery: cat /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor If it returns powersave, try switching to performance: sudo apt install cpufrequtils sudo cpufreq-set -g performance #### 2. Install and Configure TLP TLP is a powerful tool for managing power, but it needs tuning: sudo apt install tlp tlp-rdw sudo systemctl enable tlp sudo systemctl start tlp Then edit /etc/tlp.conf and adjust settings like CPU_SCALING_GOVERNOR_ON_BAT=performance. #### 3. Use PowerTOP to Analyze Power Usage sudo apt install powertop sudo powertop Navigate to the Tunables tab and ensure everything is set to “Good”. #### 4. Check GNOME Power Profiles Ubuntu 22.04 uses power-profiles-daemon. You can check the current profile: powerprofilesctl Switch to balanced or performance: powerprofilesctl set balanced #### 5. Update BIOS/UEFI Check your laptop manufacturer’s site for firmware updates. Some power-related bugs are resolved at the firmware level. #### 6. Test with Live USB Boot from a live Ubuntu USB and see if the issue persists when unplugging. If not, it may be a config issue in your current install.
