Question about Sony CMT-CP100 CD Shelf System

1 Answer

Memory Loss I own a CMT-CP100 system which was working excellently until recently. The problem it developed is that once the mains power is disconnected, it looses all the pre-tuned station information. This was previously not so. I have resetted the system but that did not help. Your assistance is requested. Best Regards, Hugh.

    Our power was out for several hours and the Sony MHC-RG20 lost all the radio presets. I'm unable to find the manual and don't remember how to set the presets.



    Thanks for any help you can give.

    I have a nakamichi sound space 3 and when the power goes out I lose my presets and alarm settings?

    I know it is related to an internal battery but I can't seem to locate it? I have not removed the screws and opened the unit up yet. I figured I would ask if anyone had an idea on where the battery might be?

    Thanks,
    Frank

Many devices utilize a small battery for system memory purposes, such as radio station presets. It draws a small continuous current for that purpose. If your system used to keep the presets when disconnected, then I would guess that?s the case. Search for a small battery compartment in the back of the system, take out the battery and take it with you to be replaced with one just like it. If that doesn't fix it, then i hope you're still under warranty, otherwise either you'll have to live with it or take it to a repair shop. Good luck!

Who invented microsoft excel/


Excel is a spreadsheet developed by Microsoft but is by no means the first spreadsheet.



The very first spreadsheet was developed (or invented) by Dan Bricklin and Bob Frankston called VisiCalc. VisiCalc was a spreadsheet written to operate on the Apple II computer and was released in 1979. The program was sold to Lotus who developed Lotus 123 from the VisiCalc principle. Lotus 123 was released in 1983.

Excel, first released in 1987, is a development of the early spreadsheets and therefore cannot strictly be classified as an invention. Excel is far more powerful than VisiCalc but that is also a result of development over the years that Microsoft have been working on the product, and the increase in computing power.

Dan Bricklin and Bob Frankston never patented the product because software patents were almost unheard of in the 70s.

Hi guys, I have an issue with my old HP Compaq D530 CMT Desktop. The power light blinks 5 times when I power on the pc (Pre video memory error). The Hp site suggests to: 1 Reseat the DIMMs in the memory...


Try the DIMMs in another motherboard.

Download the free 'MEMTEST86+' software, and burn it to a CD-recordable disk.
Put just _one_ DIMM into your computer, and boot from that disk, to run an intensive "memory-test" of that DIMM. If it "passes" (about 30 minutes per 512MB), then repeat with the other DIMM.
