Hello.
I have an old Lenovo Ideapad laptop but with good specs
I7 4700MQ 2.40 GHz and 3.40 in turbo
12GB of RAM
GT 740 M
And my problem is that the processor, even under intensive use like an OCCT CPU test, always stays at 2.39 GHz, impossible to reach turbo speed. I have several ideas on the subject, but I would like an outside opinion.
First of all, the PC has no battery (dead), I think that the battery may provide the additional voltage needed, in addition to the power supply, to reach its turbo frequency, and then the BIOS; I cannot update it because it requires a battery that must be at least 30 percent charged. Maybe the BIOS?
As for the drivers, everything is up to date; I took care to install all of them.
In terms of overheating, there are no issues; I also recently changed the thermal paste and cleaned the dust.
Do you have any idea?

Hello
The task manager does not allow you to see the actual frequency of the cores, and I also think there's a lack of understanding about the turbo function; on this processor model, turbo mode is only functional on a single core.
To see exactly what’s happening, you need to install software like HWmonitor.
As for the battery, it does not affect this aspect at all, nor does it impact the BIOS update, which must be done while plugged in (I also advise against updating the BIOS without compelling reason).

Even with the software that indicates the frequency of each core (bench), I'm still stuck at the same frequency :(
