Gardena Sileno verbindingsprobleem opgelost

Posted on 2025-10-202025-10-21 By rolfje No Comments on Gardena Sileno verbindingsprobleem opgelost

In de zomer groeit gras als een malle. Eigenlijk zou je 2 a 3x per week moeten maaien als je het mooi wil houden, en met een kooimaaier wordt dat al snel klusje dat je uitstelt of overslaat. Dus kochten we een prachtige robotgrasmaaier van Gardena: De Sileno City met LONA technologie (daarmee maakt hij een mooie kaart van je tuin die je ziet in de app op je telefoon).

Bij het installeren meldde hij dat het lussignaal en de geleidingsdraad niet waren gevonden, ook al stond hij in de lader en was alles correct aangesloten (groen lampje in de lader). In deze post leg ik uit waar dat door (kan) komen en welke oplossing NIET in hoofdstuk 6 “Probleemoplossingen” in het boekje staat.

Drobo FS Lion Time Machine Fix

Posted on 2012-01-07 By rolfje 10 Comments on Drobo FS Lion Time Machine Fix

Many Drobo FS owners out there who upgraded to Lion were unpleasantly surprised by the fact that their Drobo no longer behaved like they used to. After months, drobo released new firmware, but it didn’t improve things all that much. With the new firmware, the Drobo FS:

  • is slow or entirely unresponsive, Time Machine backups don’t finish at all or take days
  • doesn’t show up in the Finder of Lion Macbook owners connecting through wifi
  • has a transfer speed of 20MB/s, even when connecting through GB Ethernet, regardless of OSX version (tested with Snow Leopard, Lion)

If you have one or more of the problems listed above, you will be pleased to hear that there is a “fix”, although it may not be what you were hoping for.

Macbook Pro Screen update issues

Posted on 2008-08-18 By rolfje No Comments on Macbook Pro Screen update issues

My wife has this great Macbook Pro 15″, and I “don’t mind” using it every now and then. I noticed that when running on batteries, screen updates are a bit strange:

  • When scrolling down a webpage, the page get garbled. Scrolling the garbled piece out of the window and in again sometimes fixes it.
  • When resizing a Finder window, the icons in the window flicker a lot, you can see them being cleared and redrawn.

I noticed more people having these problems on several forums, and I also read that resetting the PRAM could fix it. Well, I just reset the PRAM and it seems to have fixed it, indeed.

I used the method mentioned on Apple’s support page, which tells you to shut the computer down, and boot it up holding the command, option, P and R keys. As soon as you see it shutting down after you’ve started it up, release the keys.

This is all I did, and it seems to have fixed it.
