Firstly, lets update the BIOS click here. To help your computer run as cool and efficiently as possible, do one or more of the following corrective actions. However, you generally cannot do this easily on small wall chargers of the sort you mentioned without risking damage to the charger or exposure to potentially dangerous voltages. While the sound of the fan running all the time can be annoying, it may be the first clue that your computer is running as efficiently as possible. Of course, this means that a user can apply glue onto coils using a glue gun to suppress coil whine-and yes, people have done this successfully with PC motherboards, graphics cards, and power supplies. The glue helps reduce the vibration and noise the coils generate during normal operation. This is why you sometimes see a "glue" of sorts on coils inside electronic devices. However, the same noise can occur under a load with a poorly designed or defective power supply as the coils may vibrate under electrical stress at a sub-harmonic frequency. Under a load, a properly functioning SMPS should operate at a frequency well above the human hearing range, typically 50 KHz or higher (although some older designs operate at 33 kHz). Together, these can lead to audible noise especially in cheaper units which fail to suppress this noise. In addition, in low or no-load situations the PWM (Pulse Width Modulation) used to regulate voltage at the inverter stage will be at a low duty cycle and create a "spikey" output profile which is more prone to causing vibration in coils, and the transformer itself will tend to vibrate as well. The no-load frequency is often low enough to be within the human hearing range. The internal switching frequency of an SMPS is typically low when unloaded and increases with a load (up to a certain point depending on the design). Yes, the fans crank up when you’re playing games, but that’s expected. Most modern AC adapters are switched-mode power supplies. The HP Spectre x360 15 (2017) has acquitted itself well in this regard, with silent operation for the most part. I am based in Germany, got it directly from HP. Reply kavahox Additional comment actions. OmegaMalkior Spectre 14/16 11th gen + eGPU RTX. The sound is not very loud, but you can definitely hear it (sometimes it becomes very weak, but gets to higher pitch at other times). The varying magnetic fields generated by these components can cause them to physically vibrate at high frequency, resulting in a high-pitched noise. Crackling 'coil' noise from brand new 2022 16' Spectre. These components use electromagnetism to convert AC main power to low-voltage DC power. Most power conversion devices contains coils, such as transformers or inductors. The left click has a very hard and loud sound while the right is the opposite, soft and normal.SuperUser contributors DragonLord and Daniel R Hicks have the answer for us. If you could get a model with no issues, I'm jealous.Īnd for the model I have right now, the only thing that bothers me is that the trackpad is again different this time. HP's QC control is probably the worst I've see out of any other company. I would rather opt for a laptop that is lower spec and not deal with any of these issues at all. Tbh I regret buying this laptop even thought I got it at a really good deal. It's been my fifth replacement due to multiple issues with fan whining, trackpad issues, hinge misalignments, misaligned laptop lids and more minor issues. Sometimes it will be variations in clicking mechanism, sometimes it will be a loose trackpad or sometimes it may be both. I have an Envy x360 and one of the most common issues is that the trackpad will be different for nearly every model. It is there pretty much most of hte time nad when active, pulses up and down so is extremely offputt. It sounds like an old fan but the HDD is SSD so after doing some searching it sounds like coil whine. I believe all HP spectre laptops have coil whining if you listen carefully. Just bought a new laptop and it is performing well but the noise it is producing is far too loud.
