=== fitlet USB power behavior ===
Some ports designed to keep USB power during low power state:
# Two back panel ports: On during S0, Off during S3-S5
# Front panel ports: On during S0-S5
# Combo port (not on MintBox mini): On during S0 only
Power states:
* S0 - active<br>
* S3 - sleep<br>
* S4 - hibernate<br>
* S5 - Shut down (SW off)<br>
=== Why I get black screen when powering up Barebone fitlet? ===
You must install RAM first to get display signal from fitlet.
=== Which power supplies can power the fitlet? ===
fitlet bundle comes with external AC/DC wall power supply, providing unregulated 10–15Vdc input voltage range, 12Vdc nominal. However, any power supply able to supply ~36W from 12Vdc output 12VDC @ 3A source will be fine. === Pigtail unterminated DC cable ===Pigtail DC cable - unterminated on one end and on the other uses standard 5.5mm x 2.5mm barrel plug with mechanical twist-lock.<br>Can be used with IPC2, Intense PC, fit-PC4/3 and fitlet computers.* [http://www.fit-pc.com/web/products/accessories/fit-pc3-ipc-accessory-kit/ Order from Compulab accessories]* Order info: ** Compulab PN: 504F010040 ** L=150cm, 5.5/2.5 plug diameters, tinned ends, #16AWG [[File:Unterminated-DC-cable.png]]
=== What are power capabilities of fitlet USB ports? ===
=== Setting fitlet power consumption limit ===
fitlet BIOS allows users to set processor's maximum power consumption limit. Power setting APU TDP option accept values between 1-25000 [mW], when default value is 4500 [mW]. Higher value means better performance, and hence higher temperature. For more refer to [[fitlet BIOS guide]].
=== Audible noise ===
In very rare cases a weak high frequency audible noise can be heard from computer system - <br>
“Coil whine” and piezo noise from ceramic capacitors is a documented phenomenon that cannot be 100% eliminated. It is unlikely to be as loud as the fans found in most computers, and is usually less audible than the noise emitted by hard disks.<br>
An interesting phenomenon is that this electronic noise is often reduced under load (due to less power switching/trimming). Some users apply less aggressive power management and report reduction in noise.
=== GPIO drive capabilities ===
=== Will fitlet run off-the-shelf, common apps under Windows 7 and Linux? I read in a few places that Linux on Media boxes could leave users very disappointed, even if they get the desktop environ up, because of the few apps that run on SoCs ===
fitlet is a VERY standard PC in that respect. All Windows and Linux applications should be 100% compatible. <br /><br />Where are the "gotcha's" with other small systems?<br />Architecture (mostly ARM) - fitlet is AMD x86. <br />Non-standard BIOS - fitlet has AMI BIOS with both UEFI and legacy support. <br />Insufficient RAM - fitlet supports up to 8 gb<br />Insufficient storage / no SATA - fitlet has mSATA up to 1 TB or so. <br />Limited graphics, no DirectX / openGL - this was in fact a limitation with fit-PC2, but fitlet has Radeon built-in. <br /><br />Bottom line - performance might not always be high, but compatibility is perfect.
=== Does ''FreeBSD'' run on fitlet? ===
[http://www.ipfire.org/ IPFire] works well on fitlet.
=== Does fitlet support ''VMWare ESXi''? ===ESXi is reported to work on fitlet. A , however a known issue with i211 I211 NIC driver in ESXi has been software exist and addressed in August 2015 by Andreas Peetz of few articles:* [http://wwwblog.vkihltech.com/2014/01/how-frontto-add-intel-nic-drivers-to-an-esxi-5-5-iso/ "How to add Intel NIC drivers to an ESXi 5.de 5 ISO"]* [http://www.v-front.de"Why upgrading from ESXi 5.5 Update 3b to 6.0 fails"]
=== What are the supported boot modes? ===
Both UEFI and Legacy boot modes are supported.
=== How can I monitor CPU temperature in Linux? ===
See [[Getting fitlet CPU temperature in Linux]]
=== Using fitlet GPIOs under Python ===
Refer to [http://www.fit-pc.com/forum/viewtopic.php?f=142&t=5825 Forum example shared by DaveLangstaff].<br>
