Hi @ardias , From your description, the problem appears to be in the display assembly. The laptop works OK with an external monitor and the laptop video cable disconnected from the display assembly only. This proves that there is no problem with the motherboard or GPU as the laptop turns on and there is a display and that there are no short circuits between the wires in the laptop video cable which may be causing the problem as it is still connected to the motherboard. You could always satisfy yourself that the video cable is OK by using an Ohmmeter and check that each wire in the video cable has continuity from end to end and if they are all OK then all that’s left is the display assembly itself. Also try searching online for (insert motherboard’s board number) schematic to hopefully find them. The board number is printed on the motherboard. This may also help.

Hi @dsbarrera , The designation BZ1 indicates that it is a buzzer. It provides the “beep” when the unit is turned on or when the is an error on the display screen. It doesn’t appear to be overheated or damaged as it looks like some glue has either dripped onto it or has been deliberated put on it. Here’s a close up of your image. As you can see the substance appears to be covering the case that’s all. (click on image to enlarge for better viewing) Even if the buzzer failed it shouldn’t affect the operation of the appliance except that there will be no beeps. Is there another board that the power is connected to as the board that is in your image appears to be the control board and doesn’t have the power supply connected to it, it just has connectors for cables from another board perhaps?

Hi @tumble220 , Could you elaborate a bit on your question? Most fans spin for most of the time when a laptop is in use. For example, do you mean that it continually operates at high speed and therefore is noisier than normal? It may be a motherboard issue but first you could check the condition of the thermal paste on the CPU to see if it has dried out and needs refreshing. See YouTube videos for how to refresh the thermal paste on a CPU. Dried out thermal paste means that the heat from the CPU is not as efficiently transferred to the heat sink and then extracted by the fan, so the CPU runs hotter. The CPU has an inbuilt thermal sensor designed to signal the BIOS to increase/decrease the fan speed to extract the air more/less quickly when the temperature reaches certain thresholds It could also be a problem with the fan itself. Looking at the ifixit Asus K50IJ Fan Replacement guide, the fan has 4 wires so this may mean that it has an inbuilt temperature sensor (thermistor) and a rpm sensor to signal...

Hi, Here’s the service manual for the laptop. (A Dell Vostro 1014 is the same as a Vostro PP38L). The manual shows how to remove/replace most of the major components. To find a new battery, search online for Dell Vostro PP38L battery to find suppliers that suit you. The laptop only supports a maximum of 4GB DDR2-800 (PC2-6400) SODIMM OR DDR3-800 (PC3-6400) SODIMM ram in 2 slots i.e. 2 x 2GB. It depends when the laptop was manufactured. <Jan 2011 is DDR2, >Jan 2011 is DDR3. Check what is installed at the moment by looking at the information on the ram module itself and then search online using the information to see what it says about the type You should be able to replace the HDD with a 2.5” sata SSD to improve performance. Here’s a link just to show what SSD options are available. There are other suppliers that may suit you better. To install a camera module (supplier example only), see the removing / replacing the display assembly section of the service manual. Search for Webcam Camera M0V04 to find...

Hi, Not totally sure but it should be possible. It may depend on your exact model though if a replacement part is available or not. Here are all the keyboard modules that are available for Asus GA401IV-1D and -1E laptops. I think that these are the model numbers for a Zephyrus G14, but perhaps you should confirm it and which one you have, just to be sure. The part number for a US-English International keyboard module is 90NR03F2-R31UI0 (-1D model) and 90NR03F3-R31UI0 (1E model) When searching online using the part number only, there were only results for 2 suppliers of the part for the -1D model and no one for the -1E model who had any in stock or indicated that could be ordered. Hopefully you need the -1D part and not the -1E part, but then again you may find what I couldn’t ;-) Here’s a video that shows how to replace the keyboard module which maybe of some help.

Hi @junkernaut , Here’s the service manual for the camera. Be patient as it takes a little while to go from processing to download after you have passed the security check and clicked on Go to Download, below the document preview box. Sect 3. of the manual show the disassembly procedure Here’s a composite of two images from the manual showing the battery location on the mainboard pcb diagram on the left and the wiring diagram on the right. (click on image to enlarge for better viewing) The image on the right shows that the part number is 2409-001166. Also it appears to be a capacitor and not a battery per se, the value being 70000uF (0.07F) Search online using the part number only to find suppliers. A lot that I checked say that it is available as a special order, but you may find a supplier that has one in stock.

Hi, Since you can make it happen when you bang the machine, it seems as though there may be a loose connection, which given that the problem is random then it may be occurring due to the vibrations caused by the machine operating. I can only suggest that you disconnect the power from the washer and then access the control board to inspect the wiring from the power cord up to the board and also any harness cables that plug into the board, for loose connections etc. Also if the wires are crimped i.e. have crimped lug connectors on them, and are not screwed down onto a terminal, gently pull the wire from the back of the lug connector to see if it moves in the connector etc. Unfortunately I cannot find a wiring diagram for your model but here are the parts diagrams that may help as they show where everything fits together, mechanically anyway.

Hi @jaxrthedog , Have you proved that it is a card problem and not a software problem? What is the status of the WiFi adapter in Device Manager? If Win10 is installed, right click on the Win Start button on the left side of the Taskbar and click on the Device Manager link. When in Device Manager scroll down to Network Adapters > right click on the WLAN entry > Properties > General Tab Device status box. It it is determined that the card is the problem then here’s a video that shows how to open a Toshiba L955 laptop to replace the fan. I realize that this is not the problem but it may be useful as it shows how to access the motherboard. Once there the WiFi card should be able to be located and replaced.

@edwardnewton I don't know plasmas that well but if the lines don't move position it could by the panel data drive ICs (or their connections to the panel itself) and they cannot be replaced as they are part of the panel. If it disappears by hitting the top of the panel the connections are being reestablished, albeit temporarily. Have heard of others hitting a bit more forcefully and removing the problem for some months but haven't witnessed it myself and I don't know how hard they hit ;-) Hopefully someone may answer who knows how to resolve the problem Sorry i cannot be of more help. Cheers

Hi @technoob231 , Wondering if there is a corrupted BIOS preventing a normal start. Try a power refresh and check if this resolves the problem. Here’s how to do this: a. Disconnect the charger if connected b. Remove the main battery from the laptop c. Open the laptop and remove the RTC (real time clock) coin cell battery from the battery holder on the motherboard. Be careful when working inside a laptop. Here’s a image taken from a teardown video which shows the location of the battery (or I think that is it -couldn’t find a video for your model so hopefully this is the same or similar). Remember the orientation of the battery for when it has to be reinserted. Usually it is +ve on top - marked on the battery. Also when the battery is out, if possible measure the voltage. If it is <2.6V DC replace it. The battery type is printed on the battery. The RTC battery is non rechargeable battery that has a life span of ~5 years Once it gets too low (or is flat - no pun intended) it is possible for the BIOS to...

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

The 3rd wire is usually connected to a thermistor attached to the battery which gives the battery management circuitry in the motherboard an indication of the temperature of the battery when it is being charged. The temperature (actually a resistance measurement that alters with the temperature) is used in conjunction with the voltage level, so that the battery is not being overcharged and getting too hot and creating potential problems if left charging unattended for long periods. The charging process is halted

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

Hi, As yet I haven't figured out how to amend the link to the User Guide for this radio. The one in the Repair Guide no longer exists, so here is one that still works
