Hi TonyyStarkk ,
My suggestion is to go in bios and set it to default first, then in windows go in Control Panel / Power Options / Check High performance then go to Change plan settings / Change Advanced power settings. There go to Processor power management and you have minimum and maximum processor state. If you set minimum tp 5%, when CPU is idle it will stay at 800 Mhz. With maximum to 100% when is working will go to max frequency it has.
If you set min to 100% and max to 100% CPU will stay at max frequency all time. I don't advise you to do that, you can test only to see if it works ok.
Thanks for taking the time for writing here.
Reseting the bios to default settings is the first thing I've done before flashing the last version available, and ...yes, I didn't work for me.
I also tried changing the power settings without succes.
The only way I can get the CPU to work at a higher freq, is to boot in safe mode, or to change the BUS multiplier .
I've sent all the diagnostic logs, screenshots to Dell and they decided to replace the motherboard. I'm not happy having this experience, since the laptop is....2 weeks old.
Well, I agree with you it's very annoying to get a laptop which was broken from the start with a defect which is not easy to see unless you test and verify it for some time, and instead replacing they decide to make it pieces to change mainboard. It it was a desktop I would have understand, that is easier to replace but on a laptop ...
I don't know what is the time to return the product at the shop you bought it from, maybe it passed. I think you should check that or you already know.
I would like to know your thoughts on this.
They've decided to replace it, and they will visit my office next week, so I still have time to find out, on my own what/where could be the problem.
If there are any tests that I can do, please let me know.
You pretty much have done all the troubleshooting steps, and you took it further with installation Linux Fedora. The only thing I would recommend is updating your BIOS to the latest, but I checked your system configuration and you have the latest, so again it might be a faulty unit. Did Dell provide you with more details in regard to the issue? Is this a know issue for Dell? I believe they should have more answers for you.
Thanks for getting back to me.
Yes, they replaced the motherboard and all is sorted now.
