Hi @david_walland , Looking at the maintenance and service guide for the laptop, taken from this webpage there is no separate audio board in the laptop, so it must be an audio IC (Realtek?) on the motherboard Is the audio working otherwise OK in the laptop? If not, have you checked the status of the sound controller in Device Manager? Right click on the Windows Start button and click on the Device Manager link. Just verifying that you have checked in Control Panel to see if Bang& Olufsen control panel is there? Type control panel in the taskbar search box, select Control Panel, select Hardware and Sound, and then select the Bang& Olufsen if there. Was it working OK before the update? Try rolling back the update and check if it works again

Hi, Try a power refresh and check if that resolves the problem. Here’s the procedure: i). Turn off the laptop if on and disconnect the charger if connected. ii). Remove the battery from the laptop. Here’s the service manual for the laptop. Go to p.14 to view the necessary pre-requisite steps and then the procedure to remove the battery. iii). Disconnect the coin cell battery from the motherboard. Go to p.17 to view the necessary pre-requisite steps and then the procedure to remove the coin cell battery. iv). Press and hold the laptop’s Power On button for a full 30 seconds and then release. v). Reconnect the coin cell battery and then reinsert the main battery as shown in the manual. vi). Reassemble the laptop and connect the charger and turn on the laptop. If it starts OK there may be a message about the date and time being incorrect. This is normal as the BIOS has been reset. Once the date and time have been corrected the message won’t appear the next time the laptop is started.

Hi, Some things to try to resolve the problem: Wipe the cache partition and then check if it starts OK. (do not select wipe data/factory reset as this will erase all your data and downloaded apps) If still no good, since you have transferred all your data etc try a hard reset and see if that resolves the problem. Be aware that a hard reset (a.k.a. factory reset) will erase all your data and downloaded apps. It will restore the phone to its last system updated condition. If the phone has a Google account tied to it then you will need to know the user name and password for the account so that you can access the phone after it has been reset due to the FRP lock (factory reset protection) being enabled. If still no good after a hard reset then there is a hardware problem.

Hi, Check that the orange? plastic antenna band is securely connected. Here’s the Ifixit Samsung Galaxy S20 Plus Back Cover Replacement guide. The antenna is seen in the image below and also in the top image and better in the images in Steps.15 & 16 of the guide.

Hi, Assume you mean why doesn’t your laptop work without being plugged in? Does the laptop show that the battery is charging when the the charger is plugged in? Create a Win 10 battery report and compare the Design Capacity value versus the Full Charge Capacity value to check the status of the battery. With a new good battery they should be very close in value You may have got a faulty battery.

Hi @nick, Here’s some images from the schematic which shows the connection from the cable connector on the IO board to the chipset. maybe worth a look. (click on image to enlarge for better viewing) I’m assuming that it is just the switch that is not enabling/disabling the WiFi and not that the WiFi isn’t working at all or activated - check BIOS maybe for WLAN on/off option.

Hi, Some things to try to resolve the problem: Wipe the cache partition and then check if it starts OK. (do not select wipe data/factory reset as this will erase all your data and downloaded apps) Start the tablet in safe mode and check if it starts OK. Here’s how: With the device powered off, press and hold the Power button (located on the top edge) until the Samsung Galaxy Note Pro logo appears then release. With the Samsung logo onscreen, press and hold the Volume Down button (located next to the Power button) until Safe mode appears in the lower left of the screen then release. Note the tablet goes through the entire boot up process before showing Safe mode. This may take 30+ seconds. If it starts OK in safe mode, then a downloaded app is the cause of the problem. The trick is to find out which one. You will need to uninstall each downloaded app, one by one and test the tablet in normal mode between each uninstall until it works OK. When it does then the last downloaded app that was uninstalled was the...

Hi, Here’s a link that may help regarding how to test the LED lights. See Interior Lights section I realize that the manual is not for your model but looking online the model shown in the link above shares the same service manual as your model, so hopefully it should be the same. It could also be a faulty door switch, part #953 case parts diagram. The supplier linked is only to show the part and its location. If a part is faulty i.e. LED light or switch, there are other suppliers online that may suit you better. Just search for GNE29GSHCSS parts to get results To test the door switch, check if the fan inside the refrigerator compartment, stops when the door is opened and starts again when you manually operate the door switch. Normally the fan will run as long as the compressor motor is operating. The fan is behind a panel so you won’t see it. Feel for the air coming out of the vent or listen for it starting and stopping when operating and releasing the door switch. The door switch has two functions. It...

Hi, Check that the base Picture Style is not set to monochrome. Here’s the user manual. See p.91-92

@petersir Since it is a new laptop (2021 model) then it will be covered by either a manufacturer's warranty or under the Newegg returns policy. Contact Newegg in the first instance and ask them. Do not attempt to open the laptop as this will no doubt void any warranty or guarantee that may apply.

The 3rd wire from a battery is usually connected to a thermistor attached to the battery which signals the temperature (resistance value changes with temp) to the battery management circuit in the motherboard.

Charging will be halted to if it got too hot before being fully charged, which may create problems e.g. a fire

If leaving the 3rd wire disconnected, the battery should not be left unsupervised whilst it is charging

Hi @captainsnowball ,

FYI

voilà French exclamation - meaning “There it is!” or “There you are!”

The “red thing” in Step 3 is most probably an IR filter, to filter out visible light to improve IR operation
