STK1AW32SC how to open and change the cmos battery

The tv-stick will not start up any longer, The BIOS is not accessible. The monitor screen gets black at start up and remains black.

According the Intel manual the cmos battery can be the cause of bios update or startup problems. Is it worth replacing the battery?

I would first try disconnecting the battery for 10 minutes (to reset CMOS) and then try powering on again. This (still) requires opening the unit. To do so, carefully,

 

  1. Pry off the top cover of the ICS. Start near the HDMI connector and work down both sides to the other end of the unit.
  2. Unplug the fan to separate top cover fully.
  3. Remove the two screws holding down the board.
  4. Pry the small antenna board out of its slot.
  5. Lift the board, bringing the antenna board along with it, out of the chassis.
  6. Unplug the battery.

 

Reverse the instructions to put it back together.

 

I took apart an older FC ICS. I was unable to get a hit on the web for a replacement battery labelled "KTS 56 CR1220W 3.0V". I did get hits for "KTS CR1220W", but the connector does not look right.

When staring opening from the HDMI plug side I succeed until the small opposit side.

This will not open.

Do you have a suggestion how to open this short side without damaging the enclosure?

Your help will be appreciated!

Hello GWens,

 

Due to the form factor of Intel® Compute Sticks, this procedure, opening the enclosure of the unit, is out of the scope of support.

 

Hopefully, other community members will provide further recommendations to address this issue.

I didn't have to do anything special with the FC ICS. I know that, with the CC ICS, there is a screw that must be removed from the outer chassis (at far end from HDMI connector and under the sticker) before the lid will come off. Unfortunately, I haven't a SC ICS that I am yet willing to rip apart.

You are right! I found the hidden screw and succeeded in opening the case without damage. I will inspect the battery asap and post the result. Thanks n.scott.pearson for your help.

After opening of the PC Stick it appeared that I only had to remove the heat sink. After that I could unplug and take out the battery. The voltage of the battery was 2.44 V so I replaced the battery by a new one: model CR1220 with soldering pins.

The new startup is ok: Windows 10 appears.

Starting up while holding the on/off button for 3 seconds, in order to get access to the BIOS, is no success: the TV display remains black.

Probably something is wrong with the BIOS.

Do you have a suggestion what to try?

Thanks for help.

Hello Warner G,

In the mean time the opening problem has been solved and posted but I understand your point.
