Quick tip: Coffee stops your PC going to sleep while downloading

Craig was sucked into the endless vortex of tech at an early age, only to be spat back out babbling things like "phase-locked-loop crystal oscillators!". Mostly this receives a pat on the head from the listener, followed closely by a question about what laptop they should buy.

Ever been partway through a huge download, and Windows sends your PC to sleep, forcing you to start again? We have the answer.

The problem is in applications not being written with Windows' sleep APIs in mind. Firefox is a huge culprit, having not been compliant for at least six years.

Built for Windows 7 and Vista, Coffee is the answer to your prayers. It monitors a specific network interface, and, if it detects downloading or uploading at a higher rate than the user sets, it prevents the computer from sleeping. Setting the threshold to 0 tells Coffee to stop monitoring.

We knew Coffee was great for many things, but preventing broken downloads is a new one.

Once set to run with Windows through the Extra tab, it'll sit in your system tray, making sure you don't suffer from broken downloads again.

As with most 32bit software, it will work on a 64bit system. Just downloaded and it started up.

Or you know, could always just set your computer not to go to sleep.

Yes, but do you want to have to change that setting when your downloading large file/s and then reset it when your finished?

Is there any real benefit of even letting your computer go to sleep anyway?


Craig Simms posted a reply   

Those who are energy conscious will find it of benefit.

Why not just turn the computer off? If anything i've always found that to be faster.

Boot up time should be significantly reduced from a suspend to RAM or disk state, especially where an SSD is involved. It also allows you to resume where you left off, rather than having to open everything again.
