Hi, It may be that the battery is failing and needs to be replaced. Even rechargeable batteries have a lifespan. Here’s the Ifixit Samsung Galaxy Tab A 9.7 Battery Replacement guide that may help. Replacement batteries are available online. Search for EB-BT550ABA to find suppliers that suit you best.

Hi, Looking at the user manual it appears that the only way to charge it is via the home base. See p.2 (shown as 5/13 at top of manual document) Here’s the Ifixit iRobot Roomba 655 Pet Series Repair guide if you wish to check if the charge contact points on the vacuum are OK etc.

Hi, Here’s the owner manual for the laptop. Go to p.20 to view the necessary pre-requisite steps and then the procedure to remove the systemboard. The systemboard has to be removed so that the DC-In jack (suppler example only) can be removed/replaced as it is soldered to the motherboard and not just plugged in. If doing this yourself seems too daunting, contact a reputable, professional laptop repair service and ask for a quote.

Hi, It’s strange that the parts list for the laptop only shows 2GB and 4GB DDR3L 1600 modules and not an 8GB module. {click on Select Commodity > Memory (9)} Either it only supports up to 4GB or if it does support 8GB then you may have to try another module in case the one you have is faulty or somehow not compatible with the laptop.

Hi @stuig, I suggest that you replace the backlight LED strips or replace all the faulty LEDs and then check if the backlight stays on without the flickering. Other LEDs may also be on the verge of failing and this may be causing them to cause variations to the current flowing through them affecting the brightness.

Hi, Here’s the owner manual Here’s a link to the parts if you need any. There are other parts suppliers online that may suit you better. Just search for 385.16126200 parts to get results.

Hi @smittyc , Try to reset the machine as shown in the image below. (click on image to enlarge)

Hi @Hai long Pham You may have to try a full power refresh. This involves removing the main battery and then disassembling the laptop and then possibly removing the motherboard so that you can disconnect the RTC battery from the motherboard and then pressing the power button for a full 30 seconds. Then reconnect the RTC battery and re-assemble the laptop and insert the main battery and connect the charger and try turning it on. I don’t know your laptop model, so I say possibly removing the motherboard from the case as I cannot see the battery when viewing this disassembly video so I think that it is on the underside of the motherboard as it is on some other Asus motherboards I’ve seen. Note: When you have removed the RTC battery, measure its voltage. If it is <2.5VDC, replace it. These batteries are a non-rechargeable Lithium battery which usually last about 5 years. Their function is to maintain the BIOS settings when the laptop is turned off. When the voltage gets low, sometimes the settings can become...

Hi @alsjdkflks, You should be able to buy an alligator clip (example only) and slide it onto the end of the lead. If it is too loose or too tight you can either crimp it on or expand the opening a bit to suit. Here’s a zoomed in image taken from the 5th image for the part in the ad, to show where I mean.

Hi @ohno89 , What is the make and model number of the refrigerator? Check that the door seals are OK. Place a piece of paper between the door(s) and the door jamb and with the door closed, try to pull it out. It will come out with a bit of effort but it definitely shouldn't fall out by itself. Do this at various places around the door(s), on the top, bottom and both sides. Check that the refrigerator condenser coils (you didn’t state the model so they can be either mounted on the back of the cabinet or under the compartments near the compressor unit) are clean and free from dust. If clogged with dust etc this will reduce the efficiency of the cooling system by not allowing the heat from the refrigerant flowing through it to escape more rapidly. What was/is the ice build up like on the evaporator unit? If it is being defrosted correctly there will be very little between defrost cycles but if there is a defrost problem not all the ice may be melted during the defrost cycle and it will build up more over...

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
