Timer and Stopwatch Online

Sometimes you might need a stopwatch. No reason these days to install one on your PC. Just use https://big-clock.com/

If you need a timer, you could try this: https://www.online-stopwatch.com/countdown-timer/

Paul LI’s free timer to download and install, it has the advantage that it remembers some settings:

When you press its minimize button it minimizes to tray, not to taskbar. That would be a bit confusing at first, because you wouldn’t konw it if I had’nt written it. Or download it here.

Fritzbox 7490 Info LED blinks

When you’ve got a new call on the internal answering machine of the Fritzbox 7490, the Info LED starts to blink. (It can also blink because of other reasons, which are not the topic here.)

To stop the blinking, you should listen to the call. But the blinking does not stop when you listen to the call from the Anrufe/Calls page, see first screenshot below.

No, you need to listen to the call from the Anrufbeantworter/Answering machine page to stop the Info LED from blinking. See 2nd screenshot.

F.lux

F.lux makes the color of your computer’s display adapt to the time of day, warm at night and like sunlight during the day. It is free and it is also available for Linux.

It seems that it really helps me getting into sleep mode in the night. I recommend it.

Cannot Get to UEFI BIOS in Dell Optiplex 3040

I’ve got an Dell OptiPlex 3040 and I wanted to change something in the UEFI BIOS settings.
Restarting and hitting F2 during startup is the normal way to go. But, when restarting and hitting F2, I never came to the UEFI BIOS setup.
Sometimes, the computer just started Windows, sometimes the computer hang and just showed me black screens for a quarter of an hour or so
and then started Windows.

Ok, I thought, search the net for it. I came to a site which describes
how to reboot directly to the UEFI BIOS without hitting F2.
I tried that one, but to no avail: the result now always was that the computer hang for or a quarter of an hour or so and then started Windows.

I don’t even remember how I found the solution, but the solution is:

Remove the graphics card. Use on-board graphics adapter.

Explanation: The computer was in the UEFI BIOS, it just didn’t show it on the connected screens. Strange, but true: connecting a screen to the on-board graphics adapter without removing the graphics card did not help.

Remark: I’ve got a graphics card with two ports, an AMD Radeon HD 6450. I don’t know if the problem occurs with graphics cards with a single port.
