SOURCE: HP Media Vault - Power on / fan on / front panel indicators off

I read a bunch of material found on the web. Primarily this led me to believe that the Lynix flash OS has some issues (to say the least). After carefully testing out the mom board voltages I decided that there was probably a software boot issue.

I read this at k0lee.com/mediavault/
"The MV1 has a hard reset which severs the tie to the startup.sh script that calls any of the installed software." The material on this site also indicated that the stored files would not be affected by a hard reset. So what the heck... nothing to lose. I unplugged the power, pressed the reset button and then applied power. Held the reset button for > 5 seconds. Held my breath for 30 seconds and the disk light started to flash on the front indicator panel. After a minute or two of that, the OK light came on. I pressed the power button on the front panel and the it responded. Another miracle? Hmmm. The MV shut down. I connected to the LAN and powered back on. Every thing worked fine.

I guess... there was a space issue / startup parameter corruption / enemy electron in the mix that was passed over with the hard reset at start up. Since there is on access to the OS boot process, (or source code) this is pure speculation. Although, it is reasonable speculation. Chao!

SOURCE: Pool heater will not heat

Im no pro, but I know there is an air sensor behind the main board. If the fan is running you probably have a problem with that sensor. If your lucky the air hose could have just popped off.

Well hope so you didn't damaged the sensors! try this : use the phone until battery is empty and switches off. then put it on the charger for 4 hours. If no joy,try different battery to make sure that device is not damaged and get a new battery.

SOURCE: battery will not charge on a dell d610 when plugged into outlet

I have seen this with faulty batteries.
Try changing the battery.
Also, check in the BIOS that the adapter you are using is recognised and shows a state of charging with the battery in.

1. Remove laptop battery, optical drive, hard drive and ram. Remove external peripherals as well.

2. Make sure AC Adapter is not yet connected to the laptop. Pressand hold on the laptop’s power button for 10 seconds to drain the powerflea.

3. Connect the AC Adapter for laptop to a known good power outlet, check ACAdapter power LED if it is on. Try to sense if AC Adapter is not makinga bit of noise when it is plugin to the wall power outlet.

4. Connect now the AC Adapter tothe laptop. Check if AC Adapter LED stays on when it is connected tothe laptop. If the LED stays on means the AC Adapter is fine. If the ACAdapter LED turned off check the AC Adapter pin that goes to the laptopAC socket if it is loose.

5. If AC Adapter stays on after connecting to the laptop try topower on laptop. If no power LED comes on then this is motherboardproblem.

6. Before replacing the motherboard there is one checking needs todo. If you can open your laptop bottom part then good, do this whenlaptop is not connected to any power source. Try to reseat the laptopCMOS battery then try to power on laptop after, if still fails thenreplace motherboard. I hope this helps.

Powerware 9120 BUS Unbalanced error display


I've had this same issue what it boils down to is that the Power IN is not being distributed properly across the Power Outlets.

Step 1. unplug everything from the unit and power the ups down. If the alarm clears itself the UPS is mostly likely fine. if it doesn't not clear send it in for repair

Step 2. If step 1 cleared the alarm try distributing the decives across the outlets differently.

There are two inverters so two output if everything is plugged into one side (ie a power bar with 10 things plugged into it) and nothing on the other side this could cause the alarm.

hope this helps

Battery test failed


1. Replace the batteries because they NEED to be replaced. It is not wise to ignore alarms.

2. Remove the battery backups. Without good batteries they are useless so why waste your time silencing alarms. Just make sure that the computers are plugged into a surge-protected outlet and you save your work frequently when there is bad weather.

FYI: Retail UPS batteries are only good for 2-3 years and high-end commercial batteries are only good for 3-5 years.

I hope this helps.

Truck won't start, no click, no nothing


Here are a few things you can try.
Clean the battery terminals and the inside of the battery cable ends with a wire brush. Make sure the cables are a snug fit back on the terminals. If that doesn't fix your problem check to make sure both the positive and the negative battery cables are good using an ohm meter. You should read just a few ohms. While you're measuring the cables wiggle them around. If you see the resistance jump up while you're doing the wiggling that cable may be bad. Follow the negative battery cable to where it makes connection to the engine block. Make sure this connection is a good clean metal to metal connection. If you aren't 100% sure the battery is good try jumping it with another car.
I hope these suggestions help you out.

No Power Up


The battery charger inside the UPS is faulty so check the transistors including the rectifier on the heat sink. Replace the faulty ones and your UPS will be good. I strongly suggest that you check all the transistors on the PC board just to make sure that the whole board is ok after replacing the transistors

Follow the steps below to determine whether the problem is related to the AC adapter or your notebook system board:
  1. Remove the battery and disconnect all external devices from the computer.
  2. Hold the Power button for several seconds, with all power sources removed. This drains residual power from the system, and may correct many problems.
  3. Connect the AC adapter to a wall outlet and plug the other end into the computer.
  4. Press the Power button .
  5. Is the Power indicator light (LED) on or off?
****If notebook power indicator light (LED) is on, the AC adapter is working correctly***
If the power indicator LED is off, the AC power adapter may need to be replaced. To determine if the AC power adapter needs to be replaced follow the steps below:
  1. Ensure that the AC adapter is plugged directly into a known working wall outlet.
    NOTE: To check the wall outlet, plug in a different known working device like a light, radio etc.
  2. Check all of the following connections:
    • The connection from the AC adapter to the wall outlet.
    • The connection into the power adapter from the wall outlet.
    • The connection from the AC adapter to the notebook.
  3. Press the power button again to test the notebook PC.
  4. If the power indicator does not turn on, remove the AC power adapter from the notebook PC and re-insert the battery. Then press the power button. If the power indicator light still does not turn on, then the AC Adapter needs to be replaced.
*****Reseating the RAM may resolve this issue.****
Step 1 - Remove the battery
  1. Slide and hold the battery release latch to the unlock position.
  2. Use your finger to lift the battery up and out.
Step 2 - Remove the memory module
  1. Locate the memory module cover on the bottom of the notebook.
  2. Remove the screw that covers the memory module.
  3. Use your finger or a flat head screw driver to lift the inside edge of the memory module and remove it.
  4. Push both tabs outward simultaneously to release the memory module.
  5. Grasp the memory module by the edges and pull gently to remove it.
  6. After removing one module, replace the memory expansion cover and then replace the screw.
Step 3 - Replace the battery
  1. Insert the battery into the notebook.
  2. Push the battery into the base enclosure until you hear a click.
  3. Connect the AC adapter and turn on the notebook.
fter the memory is reseated, connect the AC adapter and turn on the notebook. If the notebook boots normally and the Windows desktop appears no further action is needed. If this problem re-occurs often, contact an HP Support Specialist to schedule a repair.

UPS 9120


did u check the fuse inside the ups?
