Re: USB Mug Warmer [OT]
@ 5 volt and 0.5A, we get 2.5 Watt. So... It may keep it hot a bit longer, I would think that placing the cup in front of the PC outlet fan may do more. But it does looks cool!

I have such a device, but I wired it to an old 5 V cell phone charger. I do not see that it helps very much as the bottom of the mug is ceramic and therefore insulated. I suppose if you had a mug with a metal bottom it would be more practical. -- Dotan Cohen http://gibberish.co.il http://what-is-what.com ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il
[YBA] Lenovo z580 BISO setup horror story
Dear Colleagues,
I recently purchased a Lenovo Z580 Ideapad from Macsanei Hashmal.
I replaced the 750GB HD with a 240GB SSD and installed Squeeze. The
installation succeeded but I was unable to log out - had to hold power
button to force off.
Same story with Wheezy.
Installed Ubuntu 12.04. Seemed to work fine but I am too old to deal wuth
Unity, so I installed Mint Xfce.
After installing Mint I am not able to get into the BIOS setup menu no
matter what I press, either the main power key or the recovery key,
whether F2 or F12, I always get to a limited boot menu that is not
editable.
If I connect an ethernet cable, it tries to PXE, then TFTP boot until I
press escape - not so secure.
Can't find the CMOS battery if there is one and can't find service
documentation that would tell me where it is.
Re-installed the original 750GB HD and booted into Windows 7 Home Edition.
Downloaded new BIOS from support.lenovo.com but it wont install.
I guess I should have purchased ASUS.
