Wow, by pressing the right-hand button on my APC Back-UPS XS1000, I can see lots of status information, nice! I also have a Back-UPS XS900, and many years ago it shut down and beeped constantly, if memory servers, and so I replaced the fan, and put it back to work. Now the dual-batteries need to be replaced. I have them out in the garage, but I had taken the specs to my local W*ntronics store and they flatly stated that they would not order what I was specifying, and I refused to buy APC-branded batteries, thinking that I could save lots of money... I should probably pursue this and post the info at my web site. I recently took lots of pictures of the new memorial to Nikola Tesla down by the Falls, I need to see about putting those online, as well. If you haven't done so, I highly recommend reading "The Man Who Invented The Twentieth Century : Nikola Tesla, Forgotten Genius Of Electricity," by Robert Lomas. - -- Daniel Villarreal PGP key 2F6E 0DC3 85E2 5EC0 DA03 3F5B F251 8938 A83E 7B49 https://pgp.mit.edu/pks/lookup?op=get&search=0xF2518938A83E7B49 -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQEcBAEBCAAGBQJXaAOWAAoJEPJRiTioPntJ2z8H/R/GQR3tWe7u46TxY1awx8aa FFa/6G/UDbjKvrlOYfa8OZ7+e30zy4pQlfjnBTdtkDxvAB6xT42V/Zef8uDDL1Ac DFUXilNZHBH/k/zgR7na+jTRhV5r7bF1uw1eGdSUXQ3dIWt/uFlP790htxx8Vcot MDwjgXMMpRGCkVRVPQHpeAKEyGxnNS7yvUdDnuMqdddcHIWsX88gbhdYaNti4JQr 7EpttsiTRKI9fdvs9ULeeMpMqTkivzo4OscKasVi24pl7EeD/f5ZtDlcC5zMhWsU yfJ7p9ajmnrKXo2+tHz3APHFaTlxfPUSq179PL+629xrzpmiLakD6L7Fj4/24B0= =WDoT -----END PGP SIGNATURE----- --- Talk Mailing List talk@gtalug.org https://gtalug.org/mailman/listinfo/talk
