Hi, You don’t say what the problem is or what you have tried to do to fix the problem but replacing the WiFi chip seems a bit excessive. Have you tried disabling the smart network switch to see if this fixes the problem? Here’s how to do this: Enable the mobile data connection. Then go to Menu -> Settings -> Wireless and uncheck the smart network switch option Your internet connection may not be so stable anymore as it won’t be switching between the WiFi and the mobile network internet connection trying to achieve the most stable connection possible. Also try wiping the cache partition in case there is corrupted cached data that is affecting the WiFi

Hi The impurities in the water causes corrosion and provides circuit paths for the electricity which were not in the phone's operating design and could damage the components. The corrosion starts immediately and is ongoing until it has been properly cleaned away First do not try to charge or to turn on your phone and then remove the battery as soon as possible to prevent any further damage. Then you need to dis-assemble the rest of the phone and clean all the affected parts using Isopropyl Alcohol 99%+ (available from electronics parts stores) to remove all traces of corrosion and water. If possible, do not use "rubbing alcohol" as in some cases this is <70% IPA, can contain additives and is not as effective. If you do have to use it, check the label to verify the amount of IPA Here is a link that describes the process. Electronics Water Damage As always with electronics, especially surface mounted pcb be gentle when handling and especially when brushing away the corrosion. You do not want to remove any...

Hi If you need a more detailed guide, here’s the hardware maintenance manual for the laptop, that will help with the dis-assembly procedures.

Hi, Just wondering if the 22 pin connector on the HDD (is it 44 pin - 22 pins in row on top separated from 22 pins in row underneath?) actually unplugs from the HDD exposing 44 male pins, like the 4 pins to the right? If so then you could use an ide to USB 3.0 adapter (supplier example only) to connect the HDD to the laptop. Note the 44 pin (2 x 22 pin) female connector on the side of the adapter whereas the other connector is for a 7 + 15 pin connector. The 4 pins to the right are for the master/slave settings for the HDD and should be left as is, i.e. in the master position. Here’s an image from the HDD datasheet that shows what the master/slave pin configuration is. (click on image to enlarge for better viewing)

Hi @stevieh , Connecting a charger should give an indication on the phone if the USB connector and its connection to the systemboard was OK, as long as there is no other problem with the systemboard that is. The battery may be depleted so far that it may not be able to provide enough power to do anything without it being recharged first (or replaced - may be depleted beyond recovery). Use a strong light and a magnifying glass to visually inspect the USB port for any bent or broken (missing?) pins (check pins 1, 4, 9 & 12 top and bottom rows) or any obstruction e.g. lint, in the port enclosure that may be preventing a good electrical connection. If there is any debris do not use a metal pin or probe to try and get it out as you may damage the pins or cause electrical problems in the phone. Use a vacuum cleaner instead to try and suck it out. If still no good then use a sharpened wooden toothpick to gently prise it out. If the port seems to be OK, check if the port seems securely connected to the board. To...

Hi @damorejodane, Things to try: Wipe the cache partition and check if this resolves the problem. Start the phone in safe mode and check that it works OK. If it does then a downloaded app is the cause of the problem. You will need to uninstall each downloaded app, one by one and test the phone in normal mode between each uninstall to see if it works OK or not. When it does then the last downloaded app that was uninstalled was the culprit. (A downloaded app is one that you installed on the phone and did not come pre-installed on the phone when you first got it). If the two suggestions above do not resolve the problem try a factory restore (or reset) and check if this fixes it. Be aware that a factory restore will erase all your data and downloaded apps. It will restore the phone to its factory default (or last system updated) condition. Therefore it is important to backup the phone to the cloud or a computer before performing the factory restore. Also if the phone has a Google account, write down (or find...

Hi, Not sure but I think that it may be a RM-C3149 but I can’t find one or even the TV user manual to verify. If you have a paper copy of the TV’s user manual, there may be a picture of the remote in it, which shows the functions of each key etc and the remote model number may also be shown on it. Just a thought. If you can’t find one perhaps this may be an Android option (or Apple option) to consider,. Otherwise you may have to try a Universal remote

Hi @herotix , I don’t know the answer but here’s the maintenance and service guide for the laptop taken from this webpage. On p.10 of the guide you will find the various part numbers for all the country specific keyboards / palmrest assemblies available for the model. I don’t know if these keyboards are backlit or not but perhaps if you open the laptop as per the guide, you may be able to find the keyboard (or palmrest keyboard assembly) part number printed on your assembly and then search online using that part number only in the search term of your browser to find suppliers of the part. Unfortunately it may involve completely dis-assembling the laptop. Just an idea.

Hi @blackboss Please verify which model that you're asking about as there is a BLU Studio Max 5.0 and a BLU Life Max 5.0. plus some others I haven’t listed After 5 years of non use, regardless of anything else the battery will have to be replaced as it will have become depleted beyond recovery. Also depending on how and where the phone was stored there may be other internal damage to it. Once the model is known search on YouTube or even here on ifixit for your model teardown to hopefully find guides or videos that show how to open the phone so that it can be inspected and tested and any components be replaced if necessary. The ”standard” version phone with the same name may be similar to the “max” version only that the screen will be smaller so if you can’t find anything on the Max try using the same standard phone name guide if you find it.

Hi, Can you hear the HDD spin up or hear the Windows Startup sound indicating that the laptop may have booted into the OS? If so, try connecting an external monitor to the laptop's vga port (or HDMI port if it has one) and check if there is a display on it when the laptop is turned on and booted into the OS. Don't forget to press Fn + F3 to toggle the display between the laptop screen only, the external display only or both on together. If there is a display on the external monitor, try shining a torch at an angle close to the screen and check if you can detect any images at all when the laptop has been started. They will be very faint if they are there so trying this in a darkened room may help. If you can detect images then there is a problem with the backlighting in the screen. If you can’t hear the HDD spin up or get the Windows Startup sound, try getting into BIOS on startup by pressing the Novo button (between the Power button and the System status indicator lights) and hopefully getting a display....

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
