C0530SA-1C will not operate. Blinking red light and yellow sanitize light is on. There are no codes showing and nothing lit. Reset attempts do nothing (no response to any buttons)

OK unplug machine, plug back in push on button. unit should start if not and both red lights are on with no numbers or letters showing then you will need to replace the board assuming you have not already changed it. All new boards are built for multiple machines and have a selector switch on the back side. You have to look at the paper work that comes with new board for your model number and set switch to correct setting or the board will not know what machine it needs to control. Before you install a new board make sure you ground your self to the cabinet so there is no static electricity to transfer to new board causing it to short out.

My wd elements externa 1tb shows up but wont load just keeps telling me to format it tried on different laptops and still nothing but when i plug it into my tv it loads fine have uninstalled drivers and...

Click on Start, then RIGHT-click on My Computer, click on Manage. In the left pane expand Storage if necessary and click on Disk Management. Look in the LOWER RIGHT pane and scroll through all the hardware devices it shows there.

Do you see that external drive there?

If not, you have a hardware problem.

IF you can see the unit in Disk Management's lower right pane, look at the main block which has info on it.

It will show a Volume Name like My Disk or something, a Windows letter name like E, a size, a File System like NTFS, and a status. What are those?

If it simply has no letter name you can assign one by right-clicking on it.

If its File System is shown as "RAW", you have a little corrupted info in the disk control files. It may ask if you want to Format the disk and you are right to NOT do that.

3. Does it display the same info if you connect it to another PC?

4. IF the unit lights up but does not show anywhere as a valid piece of hardware, it is still possible that the HDD inside it is OK with good data, and the problem is with the case - its power supply or communication interface chips.

If that is the case, a simple way to check is to open the external case , uninstall the HDD unit inside, then install it temporarily in a desktop PC.

BUT your external unit MAY be one designed for use with laptops, and those have slightly different connectors on the, you would need an adapter to make the connections to the desktop machine.

But if you can do that, a good HDD will just show up like any other installed HDD. If that happens you can look more closely at the empty case as the culprit.

hope this helps

My danby model dpac90061 plugs in and wont turn on

Hi There,
I have just spoken to one of our technicians and he said that if the there is a red blinking light that usually means that the bucket or drainage system is full. If that is not the issue, it could be a malfunction in the touch pad. If the issue is not the bucket, please contact our customer service department regarding repair. (1-800-26-Danby) We are available Monday to Friday from 8:30am to 4pm EST.

Media buttons along top, power button, power indicator, and mousepad lights lite up as soon as AC power cord plugged in, without having to press power button at all. Nothing else ever happens, HD spinning...

1) Unplug unit.
2) Remove battery from unit.
3) Flip unit over onto it's top, showing the bottom to you.
4) On most HP's, there's a small compartment where your RAM is held. This is in the almost direct middle of the laptop. It should contain either 1 to 2 small screws. Remove the screws.
5) The door should be able to pull up and it will expose your memory.
6) Remove the memory (there are two latches that hold it in place on the sides of it, spread the latches and lift up on the memory.. you might feel a little pressure.. it's okay.)
7) After removing the memory, flip the unit back over, plug it in and power it on.
8) The unit will beep a couple of times and shut back off.. this is a good sign.
9) Remove power cable again, flip unit back over and reinsert the memory.
10) Screw the memory cover back down.
11) Reinsert battery, plug power cable in and try to power on again.

good luck, hope this helps! if it does.. please rate for me ! :)

When I try to plug in a second Iomega Prestige drive (an identical 1TB), nothing shows up. I can only access my second drive if the first is unplugged. How can I use both at once? Running Windows 7.

The reason for this is that they both have the same drive letter.
with the "Missing" drive plugged in Right click on "Computer" and go to manage then select "Disk Manager" Right click on your drive and change the drive letter to something else ( say E to drive "G" ) you will receive a warning that some programs may not work and select OK.
Now when you plug in your drives you should see both of them

I turn my Acer on and nothing happens. The light

Try this it worked for me

Updating the BIOS will require a USB flash drive to store the BIOS information on during the update. To perform the update to the BIOS:
  1. Go here and download the latest BIOS for the netbook.
  2. Extract the files from the downloaded zipped BIOS file.
  3. In the Dos_Flash folder, rename the BIOS file from 3310.fd to ZG5IA32.FD, in all capital letters.
  4. Copy ZG5IA32.FD and Flashit.exe to the USB flash drive
  5. Ensure that the AC adapter is plugged in.
  6. Insert the USB flash drive into a USB port.
  7. Press and Hold down the Fn and the Esc keys together and press the power button.
  8. When the unit's power light comes on wait a few seconds and release the Fn and Esc keys.
  9. After the keys have been released the power light will start to blink.
  10. During the BIOS update process the display will be blank.
  11. Let the unit run and after approximately 1 to 7 minutes, the unit should reboot and the BIOS will be updated.
If the unit fails to reboot, or the BIOS was not updated sucessfully, try the steps again. If the unit continues to fail to reboot, the unit may need service.
Note: These instructions are only for the Acer Aspire One AOA-110 and the AOA-150 netbook series and should not be performed on any other model Acer Aspire One.

Try rebooting and see if it shows up properly. If it doesn't, there could be a conflict with driver letters.

Right-click My Computer and choose Manage
Left-click Disk Management
See if your device is listed there. If it is try assigning it a new Drive Letter Right-click and choose Change Driver Letter and Paths.
Click Change.
Choose a new drive letter, problem something lower than E.
Click OK.

Unplug and reattach your device and see if it will work properly.

Mini refirgerator stopped cooling, interior light

If nothing is running but the light is on you might want to unplug the unit for about a minute. Then plug it in. If it starts up again then do nothing. It just had to be adjusted. If the display shows a er then it could have something wrong with the thermistors. If it shows 2 dashes then let me know and I can try to walk you thru a program to get you backup and running again. If 2 dashes you will have to get to the plug so pull the unit out.
