Dell Laptops in general

Question

<Multiple Forum Code of Conduct violations. Edits done. DELL-Admin>I have a Dell G15 5530 (I7-13650HX & 4060) and this is absolutely the worst 1,250 dollar paper weight. I've had this thing for barely 2 years and this thing is an absolute . To start off, the BD-Prochot sensor always false triggers, basically reducing my fps (on wall power) from 200 to 60 fps. This is even when the temps are not even in the 80s (76-78 C). The second thing about Dell and their laptops is that they won't allow you to override the BD-Prochot and disable it using Throttlestop. ( 4060 TDP with NVflash is 140, Drops all the way to 30 watts during this 'low power stage when BD-Prochot is triggered). Even before NVFlash using the normal 115 TDP for the 4060 would still put it into a 60-70 fps at 30-ish watts. More recently now, I have been noticing drops to even 30 fps and sometimes the frame will completely freeze for 5 seconds or longer when playing games.  For light works as well, the performance is slow. Even browsing the internet I notice lag, for example when opening a new tab (I usually only have around 3, sometimes 4 tabs open, email, snapchat, instagram).  I also have a friend who has an Alienware 18 gaming laptop with a 4080 who issued similar problems before his motherboard got fried (Did not do any mods or alterations to his laptop) (Alienware is the premium lineup of Dell gaming pcs & laptops) I already told my friends looking to buy their own laptops to stay away from Dell. I will never ever buy Dell again and would not recommend it to other people. (Drivers are not the issue here)

Hi

Never been a serious anything and never used BD-Prochot, I used the internet to try and learn...

PROCHOT = Processor Hot — a signal activated when the CPU reaches ~100–105°C to initiate thermal throttling

If it's activating, you likely have:

A faulty motherboard thermal sensor constantly feeding throttling signals
A dying battery misreporting temperature

On Linux, you can disable BD-PROCHOT at boot; on Windows, tools like ThrottleStop toggle the MSR bit 0x1FC bit to disable it.

However, disabling it should be done cautiously — it's better to first identify and replace the faulty sensor causing the false throttling signal.

Perhaps Use HWiNFO64 (Best for sensor identification).

""Dell laptops sometimes throttle CPU due to faulty voltage regulator sensors, not actual heat"" That may be a red herring,but I am trying to learn.

Your frustration is valid—Dell’s G15 5530 suffers from aggressive BD‑Prochot throttling that cripples performance, and since Dell locks out overrides, users are stuck with sudden FPS drops and lag even under safe temps. Combined with similar issues reported on Alienware models, it highlights poor thermal/power management, making these laptops unreliable for gaming or even light tasks.                      voyafinancial
