I would like to express my thanks and gratitude for the customer service at Heinrichs Weikamp. A replacement charger - the correct one for my model - arrived by post and its delivered a 100% charge and performed flawlessly. This service was for a 5 year old OSTC that - somehow - ended up being origi...

Morning Matthias - I will drop you an email.

But to answer questions:

Battery percentage has risen from 2% to 4% overnight and remains shown in red.
Charger is blinking green approx 1hz.
Colour of PCB is brown.

To see if there is any difference I have switched to another USB port.

The slow green flash indicating charging lasted about 20 seconds before reverting to rapid green flash.

I will leave it overnight and report back in the morning.

USB source is coming from a uninterruptible power supply output rated 5V and 2.4A. Unlikely to be using communication - just power - and should be sufficient spec? I will leave it overnight and see what the battery percentage is in the morning. Currently the charging light has been blinking rapid gr...

The current display is:

T4: 3.4v
And since my last post has climbed to 1% charged.

So if T4 is correct...is there another issue here? Or should I reset it?

Quick update:

After 10 mins on the charging pad the OSTC has come to life.

Battery level is 0% with red background (this will explain dead status!).

But 0% of batter after 12 days may indicate there is a fault or issue with the battery?

Charging light is rapid blinking green.

T4 is correct, but the 100% will be correct once the battery is fully charged and displayed in green, not yellow. See manual page 44. Thanks Matthias. The OSTC has now reverted to "dead" and refuses to wake up - any and all suggestions are again most welcome. Its back on its charging pad....

Thank you for your reply. I put the OSTC back on the charger this morning...and it woke up asking for what battery was in use. So I am unsure what happened...or what changed? The computer is now alive and reporting battery 100% - can you confirm the battery should be T4 please? The serial number is ...

My OSTC 2 refuses to wake up. Here's the process as I understand it. 1. Place OSTC on charger. Green rapid flash only. 2. Place strong magnet in centre of display. Green rapid flash only. 3. OSTC remains dead. Charger is connected to a USB output of a UPS. It's rated 2.4A 5v. I would be very gratefu...

Update:

Firmware now 3.16.
When charging switches off the LED flashes red twice then reverts to rapid yellow blinking.

I will test the 24hr soak and see what happens.

My OSTC is refusing to recharge correctly. Here's the device settings plus scenario: Firmware 3.15 Battery set to T4 Battery voltage 3.6v 1. Battery 39% 2. Place on charging pad. 3. Green light blinks rapidly initially, then blinks slowly. Battery level indicator highlighted yellow - charging. 4. Af...

How "strong" does the magnet need to be? I managed to select the wrong battery type (I think it was "old one" or something like that) and now the charging takes an absolute age...maybe 4% added overnight. So far all magnets I have are not triggering a magnetic reset. And should t...
