And typically between $15-20 at the Good Will.   The two failures I've had were the processor based control from The first one just quit working. In retrospect it might have just been something loose from moving to Texas. The other was a "twist the knob" timer. The knob fell apart. I found a new, not matching, knob and found out why the old one broke. The mechanical timer seized up.   One of the microwaves I bought, I paid $10 for and rewound the transformer to turn it into a spot welder.   But, hey, if you want to spend $100-400 on a microwave oven, be my guest.       -- "I am a river to my people."

The company gains nothing other than better customer relations if they save all the invoices, you have a chance of getting restitution if you do.   Who should be better motivated to retain records?   John

Catch 22?   > Mike.   The other Lenovo Ideapad I have, the 110, came broken from the factory but not because it didn't power up, just that it came stock with a 500gig 5400 RPM hard drive, 2 gigs of (soldered-in) DDR3 RAM, a Celeron processor, and Windows 10.   Windows 10 is unusable on a PC with those specs; right-clicking takes about 20 seconds of the HDD thrashing furiously and then the right-click menu comes up. That's on a fresh from the box install of 10.   Pull the 5400 RPM drive, slip in a SSD and install Xubuntu on it and it transforms into a really snappy lightweight netbook though

bitrex <user@example.net>: Mar 26 02:22PM -0400 I have a Lenovo Ideapad 520 less than a year old, bought directly off their web site on sale last April. It's failed, no power up. Trying to get a warranty service on it but unfortunately I can't find a serial number on the mfer anywhere. Usually it's on a sticker or placard on the bottom, I have another Lenovo lappy that's like that but this one got nothing. Just a Windows hologram-sticker and a FCC wireless module sticker. Perhaps it fell off. Usually they're on a small placard that's hard to remove accidentally, tho.   Their online system has no record of my order, all I have at this point is a credit card statement showing the date of purchase and payment. Their support department says that's no good, without a serial number I've got nothing. Might it be somewhere inside? Looks like it's supposed to be an 8 digit serial.   Uneasy feeling that the one I bought perhaps simply never had one. On sale...

On > sale...   Don't you save email receipts?   That would be an argument against just handling email by one's phone and not backing up on a desktop. I use POP for that reason, and I don't automatically delete email from the server for a week in case the computer goes wonky.   Consider that clouds go away. Amazon, Fujitsu, and other clouds have all lost data...local backup is best.   John

Look165 <look165@numericable.fr>: Mar 26 10:54PM +0100 BIOS settings are kept by the battery, not only time and date. IF time slips or BSOD, it means the battery is dead or holder. If not, Flash EEPROM is dying. Anyway, if your PC can work, try HW32INFO.   David Farber a écrit le 25/03/2019 à 18:28 :

The battery is not dead. I measured it mounted in the holder at the holder's terminals. The PC works fine except for the clock. Is there some particular piece of information you want me to find with HW32info?   Thanks for your reply.   -- David Farber Los Osos, CA

However, I just needed a new battery fitted to my old one, and set about mine with a hacksaw like this ...   http://www.glitchwrks.com/2017/08/01/gw-48t02-1   [1] For the hell of it, and a break from coding with much faster RPi things, I've been wandering down retro memory lane putting life back into an old discarded Sun Sparc Classic X. (removing the X terminal nature of the beast and installing a 1GB SCSI HDD, 72-pin parity SIMM, NetBSD 8.0 etc).   It doesn't really have a purpose (unit lacks USB, CPU runs at 50MHz) but the retro experience has reignited some brain cells - so it's kind of therapeutic. In twenty-thirty years time, I'll probably have the same fun with old Core2Duo driven things like what I am using here.   For a healthy mind, I heartily recommend this time travelling retro hobby. Sure beats sudoku and eating lots of fish ...   -- Adrian C
