Random turned on LED light on laptop!

There are no hackers after you. The laptop is simply seeing no battery.
Andrew you are being paranoid now. If you want and need to, put black tape over the webcam.

Unfortunately not that model. :slightly_smiling_face:

@andrew_ysk
Can you post the output of this command. inxi -Fxxxa --no-host

:face_with_hand_over_mouth:No , i wasnt saying being hack nor being paranoid. You miss understood me.
My main point here is, LED indicator light is not Hardwired to the device it is indicatingā€¦ but rather, they are all switched on and off being mean of software, hence hacker can take the opportunity to do their spying without user knowing.
Indeed i saw the news on tv that hacker has the technology to spy on you or hear what you saying without you even noticed.
By the way, i do sometime cover my webcam (just follow what Bill gate would do) :joy: Better safe than sorry.

Err, i think this is no longer an issue, since ā€œi really believeā€ the color is according to the Graphic card used (nvidia or build inā€¦ since my laptop is hybrid graphic card).

Just wanted to look at your Graphics because it looks like you do have hybrid Intel and Nvidia. So it looks like you installed the Nvidia drivers. Did you do this on the install? You have the Nvidia 940M mobile with Intel onboard graphics i915. (HD 4600) So looks like you are using KDE plasma. Maybe if you have it set up on optimus & you can switch graphics between Intel and Nvidia. That may change the power light. I assume you not gaming. The Nvidia is dedicated Graphics. Did you try TLP?

I canā€™t remember i installed Nvidia or not during os installation, but i have not yet (no time yet) try to install optimus or nvidia (i do have a thread in forum, that someone told me to install optimus, i still have the webpage to that, but i really have no time to install it yet). I also have not install TLP yet.
I was wonder why should i install advance power management ? since i have no power issue, thatā€™s why i was hesitating to try it. also because i have no time to do itā€¦ Also because i have not finish with timeshiftā€¦ Until i get timeshift done, i halt all packages installation. just to be safe.

Sounds like too much multitasking!

Ya, also lack of time and knowledge. It took so long for me to read and understand all these technical thing, because i canā€™t rely on spoonfeeding (nobody on forum like it), but sometime i really lack of time, to solve a tiny issue, i have to browse internet and read about it, by the time i am halfway, something happened againā€¦ hence sometime i just want to get it done, donā€™t want to be expert in itā€¦ too much stuff that are not tune rightly on this laptopā€¦ i have not even install input method, because i need to type asian language sometime, i have not install confirmed my video card, i have not tune my wifi indicator led, and many moreā€¦ :woozy_face: I think that all these are too much for a person who have being using windows for the most of his lifeā€¦

Can you spoonfeed me the command to check if i am running on nvidia, and if optimus is install and configured ā€¦etc ? so i can have 1 less issue to deal with. :pray: pls

Btw, i do have TLP installed. Maybe preinstalled. I donā€™t recall i installed it.

$ pacman -Ss tlp

The command you posted already shows you have Nvidia installed and itā€™s a hybrid graphics.

Yes, Nvidia hardware is phyiscally installed from inxi output, but how do i know if the driver for Nvidia is installed ? or it is maybe just run base on default general driver which is not optimized for nvidia. thatā€™s what i want to know.
how to know if ā€œoptimusā€ is installed and configured rightly for the nvidia card ?

$ locate optimus

Itā€™s right in the output of the command.

Edit: Just so you understand this. The Intel is automatically using the kernel module and the proprietary Nvidia drivers are installed. version 455.23.04

This has nothing to do with Optimus-manager for the Hybrid Graphics so donā€™t even go there!

I have saw the graphics: Device-2 (correct me if i am wrong) Nvidiaā€¦ In windows os, there is also software that can list out what hardware you have on system. but that does not mean the driver to the hardware is installed and running without isue ? Thatā€™s what i puzzled hereā€¦ i saw the Nvidia, but i didnā€™t see any statement that shows signed Optimus is installed and is running

Oh :zipper_mouth_face:

I really think at this point i would just stay with what you have because everything is working. There are some things with switching back & forth between the dedicated graphics such as losing your work unless you have it saved first. Hybrid graphics are really designed to move to the dedicated graphics for gaming or work that requires a better graphics card than what the Intel provides.

Iā€™m not so sure you should worry about these things right now. Better that you have a system running and no problems.

Since we are here already, can you please enlighten me in regarding to this 2. I am not sure what they areā€¦ are Nvidia optimus a driver or software for nvidia card ? and is Bumblebee a software ? if not what are they ? what do they do for my laptop ? i am really hazy hereā€¦

NVIDIA Optimus is a technology that allows an Intel integrated GPU and discrete NVIDIA GPU to be built into and accessed by a laptop.

Bumblebee is an effort to make NVIDIA Optimus enabled laptops work in GNU/Linux systems. Such feature involves two graphics cards with two different power consumption profiles plugged in a layered way sharing a single framebuffer.

This is really like having a farrari but i can only drive volkwagenā€¦ if i can switch to farrari i would love to just stick with farrari, because i alway use laptop plugged in.

If you want to try optimus-manager it will be your doing because if things go wrong i canā€™t help you and this is where the problem will start. I just think it might be too advanced for you at this stage. :thinking:
