well,i overclocked my laptop, everything is fine when suddenly I noticed that when playing games the voltage goes to 1.081v which is normal, but if I increase the voltage when overclocking {I know I shouldn't} it stays the same but the charger gets abnormally hot,what does that mean, is the laptop or charger designed not to take any more voltage,if that's so, y do they let me control the voltage in the first place.. using NVidia inspector

The reason why the voltage won't increase and the charger heating up are likely directly connected... I highly doubt that the power delivery systems in that laptop are designed to overvolt, so they're probably straining to provide the additional amperage being drawn from increasing the clock speed. The charger heating up would be a combination of the additional amperage being drawn, and from the laptop trying to up the voltage. It may be that the charger is not providing enough power to up the voltage and the amperage at the same time, so the laptop simply is unable to raise the voltage.

Let's say you have a 90W charger. It provides 18 volts and 5 amps. I made these numbers up, I'm just trying to use friendly numbers. Let's say that...
Nvidia Inspector is software. It doesn't have to abide by the rules of the BIOS if it's programmed to communicate directly with the GPU/chipset (which it very well could be). Therefore, it may be able to do things that the laptop manufacturer has purposely made the BIOS incapable of doing.

If the charger heats up, I'd shut it down and unplug it immediately. We don't want your house to burn down just because you wanted your laptop to be faster.

Laptops do not possess the rugged power delivery and cooling systems that are present in desktops. They are not meant to be overclocked. I do not recommend even trying to overclock a laptop.

listen my laptop with overclock does not get higher then 65 c , at least i dont let it, i have a powerfull cooling pad,and nvidia inspector locks the amount of overclock in a laptop, only 135mhz plus, ... so laptop getting hotter is not a problem. my question was y do the sensors show that it is at 1.081v even after increasing 6mv, and does the charger get hot stopping that extra 6 mv

Let's say you have a 90W charger. It provides 18 volts and 5 amps. I made these numbers up, I'm just trying to use friendly numbers. Let's say that you raise the clocks in the laptop, causing it to draw 6A instead of 5. This would mean that the charger would no longer be providing 18V, instead it would be providing 15V because it can only provide 90 watts.

There is step down circuitry in the laptop. The lower the incoming voltage from the charger, the lower the amount of voltage available to the internals of the laptop. Since the laptop needs to convert that 18V down to 12V, 5V and 3.3V for the internals, any drop in voltage from the charger would mean more amperage being pulled through that connector. The laptop is likely hard coded to limit the amperage being drawn from the charger, so that the charger does not literally burst into flames. This means that you likely have hit the limitations of the charger and are not able to increase voltage to the core because there is no more available power.

quiet got it, meaning charger may be in danger BUT can my gpu or other internal hardware get damaged.... becaz of this specific reason.

thank u .. appreciated ure help.. but before u go.. lastly plz could u tell me if 6 mv or 12mv plus would be much dangerous , or can it be negligible.... thank u for all the support
 


I wouldn't overvolt a laptop to begin with.
