Hp laptop goes frequently in cpu overheat with no reason

0

i hope that someone can help me with this issue that is torturing me. My laptop HP ProBook 645 G2 from a week suddenly goes in overheat apparentely with no reasonable cause. The cpu goes in over frequency and the fan is constantly in action. here my inxi -F System: Host: okcomputer Kernel: 6.2.7-arch1-1 arch: x86_64 bits: 64 Desktop: KDE Plasma v: 5.27.3 Distro: Arch Linux Machine: Type: Laptop System: HP product: HP ProBook 645 G2 v: N/A serial: Mobo: HP model: 80FE v: KBC Version 04.74 serial: UEFI: HP v: N77 Ver. 01.55 date: 07/28/2022 Battery: ID-1: BAT0 charge: 21.2 Wh (58.4%) condition: 36.3/48.0 Wh (75.6%) CPU: Info: dual core model: AMD PRO A6-8500B R5 6 Compute Cores 2C+4G bits: 64 type: MT MCP cache: L2: 1024 KiB Speed (MHz): avg: 1197 min/max: 1200/1600 cores: 1: 1197 2: 1197 Graphics: Device-1: AMD Wani [Radeon R5/R6/R7 Graphics] driver: amdgpu v: kernel Display: x11 server: X.Org v: 21.1.7 with: Xwayland v: 22.1.8 driver: X: loaded: amdgpu unloaded: modesetting,vesa dri: radeonsi gpu: amdgpu resolution: 1366x768~60Hz API: OpenGL v: 4.6 Mesa 22.3.6 renderer: AMD Radeon R5 Graphics (carrizo LLVM 15.0.7 DRM 3.49 6.2.7-arch1-1) Audio: Device-1: AMD Kabini HDMI/DP Audio driver: snd_hda_intel Device-2: AMD Family 15h Audio driver: snd_hda_intel Sound API: ALSA v: k6.2.7-arch1-1 running: yes Sound Server-1: PulseAudio v: 16.1 running: yes Sound Server-2: PipeWire v: 0.3.67 running: yes Network: Device-1: Realtek RTL8111/8168/8411 PCI Express Gigabit Ethernet driver: r8169 IF: enp1s0 state: down mac: a0:8c:fd:a3:0b:4b Device-2: Broadcom BCM43228 802.11a/b/g/n driver: wl IF: wlp2s0 state: up mac: 74:df:bf:a5:68:19 IF-ID-1: docker0 state: down mac: 02:42:fb:af:42:4c IF-ID-2: proton0 state: unknown speed: 10000 Mbps duplex: full mac: N/A Bluetooth: Device-1: Broadcom BCM20702A0 type: USB driver: btusb Report: rfkill ID: hci0 state: up address: see --recommends Drives: Local Storage: total: 223.57 GiB used: 86.5 GiB (38.7%) ID-1: /dev/sda vendor: Crucial model: CT240BX500SSD1 size: 223.57 GiB Partition: ID-1: / size: 204.94 GiB used: 86.35 GiB (42.1%) fs: ext4 dev: /dev/sda3 ID-2: /boot size: 317.3 MiB used: 129.3 MiB (40.8%) fs: vfat dev: /dev/sda1 Swap: ID-1: swap-1 type: partition size: 13.97 GiB used: 17.5 MiB (0.1%) dev: /dev/sda2 Sensors: System Temperatures: cpu: 66.4 C mobo: N/A gpu: amdgpu temp: 66.0 C Fan Speeds (RPM): N/A Info: Processes: 209 Uptime: 2h 2m Memory: 11.11 GiB used: 3.59 GiB (32.3%) Shell: Zsh inxi: 3.3.2

the fan is clean. I suppose that is a Bios problem .

tnx a lot for the suggestions!

i try to reinstall the gpu driver and insall some tools for the fan and cpu controll but nothing !

Re: Hp laptop goes frequently in cpu overheat with no reason

Next time, use

[CODE]
stuff here
[/CODE]

blocks to make the command output more readable.

I'm not sure what "The cpu goes in over frequency" means. Is your CPU being used heavily?  (You can check with top.) If so, try to address that. Is the CPU actually getting hot? (You can check that with the sensors command from lm_sensors. You can use "watch sensors" to automatically run it every few seconds.)

Your CPU appears to be from 2015. That means your laptop is probably 6-8 years old. That's not too old to use, but old enough that the thermal paste might be dried out. Has the thermal paste ever been changed? This may be the problem if your CPU is indeed getting too hot but the fans are clean, especially if it happens when the CPU usage is not near 100%, and especially if you notice it getting worse over time.

Re: Hp laptop goes frequently in cpu overheat with no reason

Even without code tags, line breaks, and perhaps paragraphs, would be good (read "necessary").  Please edit your post to make it readable.

Then address what the actual load at those times is like.  Are you doing any CPU heavy work (compiling, blender rendering, etc)?

What's the output of `uptime`?  Check `top` or `htop` to see which processes are using the CPU.  Of course this assumes this information isn't already in your massive blob of text ... I wouldn't know as I'm not going to try to read it without an edit.

EDIT: and is this any different than your other current thread?  If so how?  If not, why have you started a new thread?
