comment CPU running at full capacity when boot to DOS?
Actually, I used a thermocouple attached to the heatsink and a fan connected to a constant voltage source (so any motherboard interference is eliminated) for temperature measurements.

comment IP Helper Virus?
+1 My guess here would be that something is causing problems with IPv6 Internet connection and the computer is waiting for connection attempts to timeout before trying to use IPv4.

comment CPU running at full capacity when boot to DOS?
As I wrote, I observed different behavior on systems actually running DOS and am not convinced by your argument. In my opinion, what is shown here is more related to a side effect of running the virtual machine.

comment CPU running at full capacity when boot to DOS?
@Synetech Well I disagree. The whole point of my answer is that different CPU instructions produce different amounts of heat which answers the OPs question. The 100% part is important, since from the question text, I concluded that OP is not aware of what the percentage shown in Windows actually means. As for time after HLT execution, when the CPU is waiting for something to wake it up, it is not running at all, which I explicitly mentioned.

Also a CPU executing HLTs 100% of the time is still running at 100%.

Please provide a source for the claim that sitting in BIOS or in plain old DOS will produce increase of temperature on modern systems. My experience running DOS and assembly programs on modern x86 systems with no OS shows otherwise.

@Synetech I have no idea what you're talking about.

comment Problems starting Java Web Start program on one computer, works fine on another
@HackToHell I rolled back the question since the problem actually has nothing to to with Firefox. When I try to launch the web application using Java Web Start directly or through another program (KiCAD in this case), same error occurs.

@techie007 No, as I said, booth are using same versions of Java and on this computer the application used to work few days ago. Unfortunately, I don't know what could have happened in the mean time.

comment Wifi is slower than Ethernet cable connection?
The main point is that the 300 Mb/s is the maximum signalling rate of the interface in case you can use two channels and there isn't any interference from outside sources. There is also considerable overhead due to the way the WiFi itself works. A considerable percentage of data being transmitted isn't the actual data you're sending. Instead it's data related to the maintenance of the connection itself. In wired Ethernet, that overhead is somewhat lower.

comment Computer slow after installing 32GB RAM
@John Gilmore If this isn't solved yet, what's the condition of the HDD? Did the slowdown go away after a while? I suspect that it could be windows rebuilding swap file in order to have it big enough for the 32 GiB of RAM. In such setup, the swap file might be as large as 64 GiB.

Yes, but there's just one modem there.

comment How do I clean up COM ports in use?
The hidden serial ports don't seem the be the main cause of the issue. As expected, I found numerous instances of serial ports created by my USB to RS-232 adapter, but even when they are cleaned up, I still have 11 extra COM ports set as in use.

comment How do I link two serial ports in GNU/Linux?
The microcontroller will be later used with a GPS receiver that has a real serial port which I don't have at the moment and I want to use the mobile phone to do software development on the microcontroller because both modules emit the type of NMEA sentence I need.

comment How do I link two serial ports in GNU/Linux?
Bluetooth has support for serial emulation where bluetooth adapters of both devices create virtual serial ports which to software appear as real serial ports. Bluetooth stack of the operating system is usually used to do that and bluetooth adapters that have real hardware serial ports are expensive and (at least for me) difficult to obtain. My mobile phone has GPS receiver and software which can send NMEA sentences over the bluetooth serial port which I can receive on terminal emulator on my PC and I want to redirect that to a microcontroller which will later process that data.

comment How do I link two serial ports in GNU/Linux?
Looks interesting. Is there some (relatively easy) way to say pipe capture file so that one minicom process is transmitting what other is receiving? In the worst case, even pasting a capture file into another windows could be enough.

comment What is the name for this laser printer part, and is it user serviceable?
@ArtB Do think twice before deciding to repair this printer. There are known problems with toner dust accumulating on laser lens which can lead degradation of image quality and is difficult to clean (and as far as I know Hewlett-Packard is still ignoring the problem) and the collection of toner on the transfer belt is also a problem on some units.

comment System and Interrupts causing high CPU
@muntoo Also, once you start recording, switch to drivers tab and show us what is happening there. It should show us exactly which drivers are taking most time to do their processing.
