Hi, I've recently opened my laptop that I've owned for a few years to replace a fan and had disconnected the laptop from AC power, disconnected the battery and the coin cell battery.
Once I had connected the coin cell & main battery it had turned on like normal but when in windows the option to use the turbo mode was missing and windows had uninstalled my dedicated GPUs driver which seemed odd.
Now when I use the button next to the power button, it only toggles fan boost which never was a thing until now and I haven't found a way to revert.
This wasn't the first time of me opening the laptop and disconnecting all the power sources, probably been a few times with no problems at all.
Tried reinstalling gaming center multiple times, rebooting, reset BIOS, disconnecting all power and leaving to sit with no luck.
Potentially unrelated however when waking from sleep, gaming center will rarely have the CPU temperature stick at the previous value which causes the fans to speed up and won't change until the next sleep.
Edit: Realised that the built-in speakers (Realtek) Now show as "High Definition Audio Device" and seems to sound worse. I've heard on the x25 that the mic doesn't work with a bios update and possibly this is related?
Gaming Center version 1.1.0.51
Windows 11 x64
Beast x10 MD 61883
Regards,
Rowan

Hi Rowan all you tell us sounds not real - why don't you tell us the whole story?
If you take off all power sources, replace a fan and reconnect power again, nothing in Software will or can be changed.
What happened before you were doing this "operation"? Except from changing the fan?
Taking off power and reconnecting it doesn't change anything in drivers or other Software.
Why don't you tell us which fan you did replace?
The fan for the CPU or the graphic chip fan? If it has two at all.
Did the NB get too hot before? How did you notice a fan is defective?
Did you replace the thermal paste for the chip?
Does the replacement fan has the same speed control as the one it replaced?
Did you try to install Linux in between?
Perhaps an "EMP" impuls or a shortage occurred? Did you use wist straps against electro statical charge, or did you make a potential equalization before opening the laptop?
Edit: Please tell us the MSN number.
Bye, daddle

Hi Daddle, thanks for responding.
I was cleaning out the laptop's GPU fan which I had unplugged along with all the power to the laptop and had plugged it back in and turned the laptop on. As the back cover was still of I had turned the laptop off, and windows was shutting down but the screen had gone black and my keyboard & mouse were still on but there was no response and no buttons seemed to do anything. I had left it a few minutes before deciding to hold the power button and it had turned off as expected.
However once I went to turn the laptop back on and windows had loaded, the gpu driver was uninstalled and so was the audio driver which seemed odd. And then I went to press the mode cycle button and it would toggle fan boost which never happened before and so I launched gaming center only to find turbo mode was missing and I couldn't use the fan boost button within as it was missing.
The MSN number is 30029491
I do want to point out I have replaced the thermal paste on the GPU and removed the liquid metal on the CPU with PTM7950 a month ago with zero problems. That's what confuses me as it seemed the Embedded controller has potentially reset to factory and no longer communicates properly as the startup lighting for KB and light bar no longer function but will once gaming center has launched.
On the same day (Before the problem occured it did shutdown due to thermals which was my fault and it turned on again after a few minutes with zero problems), but the problem seemed to occur once windows had frozen after shutting down.
Perhaps it's a problem with the BIOS? I did upgrade it about a year ago but if there's a way to rollback or install an older one perhaps that'd fix it?
Regards,
Rowan

HI Rowan, I can not help you any further.
it seems it got a thermal breakdown, and/ or a static discharge.
you can try to set it back to factory status by pressing F 11 during switching on. ( But it must have still the original partition layout on the Windows boot drive!)
If you changed there anything, Power Recover will not work. The same if you deleted the Recover files in the folder Recover (not Recovery!) on partition D or E .
Or you have to sent it into Medion Service for a checkup, or you get yourself a new mainboard .But the price Medion ask for is ridiculous: 1085, 63 €. I guess the guarantee is void.
May be you get it s´cheaper with Tongfang, or with a PC repairshop.. It's a TFG GM7MP7P.
Bye, daddle

Hi Daddle and thanks for your time in trying to help me.
I don't particularly think it's a thermal breakdown as it boots up just find and when it did happen it was fine afterwards, it just so happened to occur on the same day.
Potentially it could be a static discharge but it does still work but it seems like the EC has been reset.
I have already reinstalled windows before and so I don't have the recovery partition but I might look into factory reinstalling from the .wim file I copied before reinstalling.
Don't suppose there's a bios file I could try to install in case that's the cause?
Regards,
Rowan

Why and how should it have gotten an isolated EC reset? And where did the drivers gone ? And the Gaming center? Why can't you reinstall it?
I can not follow any longer. Drivers gone, suddenly "High Definition Audio Device" installed. It's really a miracle.
About a newer Bios you have to ask a moderator; but first you must state your actual Bios Version.

I think you're a bit confused. I do have the original drivers and recovery image but the partition they're on no longer exists.
I have reinstalled the drivers and Gaming center software but this did not change the problem of missing turbo mode and the button toggling fan boost.
From briefly searching the EC has a list of devices connected, and if it has been reset windows will see those devices as a new device, which is why windows didn't load the GPU & Audio driver and had reverted to the generic drivers until I reinstalled the OEM ones.
No idea why the EC has been reset, apparently it can be caused by no power from the clock battery, main battery and AC which seems incredibly rare to occur.
My current bios is N.1.09 but it isn't the original bios the NB shipped with, had updated about a year ago.
Hopefully a moderator will see is as I'm new to the forum and not aware of how to ask one for help.

I am not confused, because I followed your tales.
You forget we are not sitting next to you and seeing all the steps you undertook. Nor the effects it takes.
You wrote in Post 1 :
@Rowan schrieb:Tried reinstalling gaming center multiple times, rebooting, reset BIOS, disconnecting all power and leaving to sit with no luck.
This sounded to me like "it couldn't be installed"
Second you wrote the GPU and Audio drivers were gone, but you didn't tell you reinstalled them, like you did now:
@Rowan schrieb:.. which is why windows didn't load the GPU & Audio driver and had reverted to the generic drivers until I reinstalled the OEM ones.
How could I know ?? And so forth....
To ask a Mod you have to call his alias with a preset " @", e.g. Major_ToM

My apologies daddle for forgetting to properly inform you about the situation and state and thank you for helping.
I should of made it clear on what I've done and the steps I took.
Just to clear everything up here's the current state of the laptop:
With asking a mod, is it alright to mention them directly without them seeing this post already?
And would I be best mentioning Major_ToM to help sourcing a bios download?
