AnhEZ28 Pathfinder

@Janeq22 Seems like you will have to reprogram the DMI.

@1800ineedhead This model has LPDDR5 RAM which is soldered on the motherboard and cannot be upgraded.

@Janeq22 Does using the old SPI chip work?

@Ashish_Thapa It is normal to hear the coil whine sound. There is no problem with the laptop.

@Worsnnjos If it is a new Acer model, the product key is embedded into the BIOS.

@paomin PD charging can provide at most 100W for this model.

@Jaco84 Try to reset the projector setting.

@Receall The Aspire series has the HDMI port connected to the CPU instead. It is done on the hardware and there is no option to adjust in the BIOS.

@jespoh Check the edition of Windows. Usually, the laptop sold in China comes with a Windows Single Language edition. You will need to purchase another version of Windows to change to a different language.

@CatyFoxt AcerSense app is designed for Windows 11 only. Windows 10 does not have any extensions for the app to work.

@Janeq22 The old DMI data is on the old BIOS SPI chip.

@Sumanth2305 Check in the device manager to see if the Bluetooth driver is there.

@majoman Follow the 1st and 2nd steps in the Acer Splash Downloader section. Enter the download mode and connect the projector to the computer using USB cable. Open the One Click firmware file that you have downloaded.

@neo89skynet LPDDR5 is for soldered RAM.

@Alex_G I can't really find any manuals for that advanced settings section, but doesn't matter much. Once you select the customized mode for Microsoft Security level. Save the setting and restart into the BIOS again, disable the SVM support and SVM lock. Try to restart again if it saves these settings.

@zxcvasdf It has the same function as the other USB ports. Only the difference is that it allows charging the device when the laptop is turned off.

@zxcvasdf The port will provide 4.5W power output (5V 0.9A) maximum.

@JanSolo This model does not support PD charging. Check with some local stores to see if they have a 135W Acer charger. Works for many Acer Nitro models.

@KanishkaS Try the power reset: turn off the laptop, unplug the charger, and hold the power button for 15 seconds.

@BigTigerM Might be a bad connection from the SATA cable. Below is the video for disassembling the laptop. Try to reseat the SATA cable.
