    Bose Sound Link Mini II red power light is flashing

    Hi everyone.

    Anyone ever come across a flashing red PWR light? Doesn´t charge, doesn't turn on.
    Tried going to the Bose site and updating firmware but the computer doesn't see it plugged into USB.

    Any suggestions?

    Thanks.

      Easiest way is to call Bose up tell them what is happening. They will take you through at test procedure to correct it. If that does not correct it then there will be something wrong inside. The manual for the equipment should have the different led color codes and flashing or steady codes.

          Pull the battery and check for shorts across the battery input on the PCB. The MLCCs can short. Remove each one and test if a short is found. Usually the boost converter is OK.

          Seen this in JBL Charge 3 also. Battery will have 4v or more when disconnected, but drops to zero (protection ckt kicking in) when connected to the PCB. Symptom would be the first battery bar LED flashing, with no power or charging.

          These will work if just one input MLCC is removed; they're paralleled for ripple/ESR.

              Monitor Audio RSW12 - Green light, but no sound
              by MOSSEP
              Hi

              Im hoping someone might be able to give me some idea of what may be wrong with my Monitor Audio RSW12 Sub.

              Ive owned it since new in around 2002, so would really like to keep it running if I can, it was the first ‘decent' bit of audio equipment I ever purchased and is a little sentimental.

              The issue I had was that it would power up with the red light, but sometimes the green light would not come on and I would get no bass from it. If the green light did come on though, I would get sound out of it.

              I have already tried replacing all of the...

              HP Elitebook 845 G8 dead, only caps lock flashing 7 times. Charging light always on
              by esqmooo
              Hello everyone.

              This is my development machine. I've been using it since two years and half without any problem except sometimes it wouldn't wake up from sleep.
              Lately the issue became more frequent and powering it up would take few seconds to show the POST screen.
              Then the computer refuses to power on at all. Now only the caps lock button flashes 7 times then stops. The charging light is always on whenever a power source is connected (battery or charger).
              I tried long pressing on the power button, after several seconds it would go off then when the button is released...

              Hello Community!

              by ChaosLegionnaire
              so i took out one of my spare gigabyte ep35-ds3r mobos from storage for use to do some cpu, ram and video card testing of stuff i bought from ebay and got for free from momaka. he bought 50 e8400 cpus for cheap from ebay some years ago and i decided to help him relieve him of some of his supply since he had waaaay too many!! what did we say about hoarding too much stuff and depriving others of them?! *cough* socialism *cough* lol!
