Many UPS's have warning lites, or will beep a code (e.g. three beeps might mean "replace batteries") Having said that it's my experience nine out of ten problems ARE related to batteries. Nevertheless various boards DO short out, transformers will short (though in your case I'd consider it down the list) An owners manual or, if available, a service manual is probably available from the manufacters website. Often a call to the tech support people will point you in the right direction.
First you need a tech that is qualified and has experience in Annual PM's on this type of unit. Symmetra is a module type unit. there is hardly any "tune up' to do to this unit. Test the batteries and insure all modules all ok, this includes the intelligent modules that pull out. Review past alarms that have been recorded and insure that no major alarms are present. Do a battery test from the display interface. Clean the area around the UPS.
Yes, The batteries in UPS systems have a 2.5 to 3 year life span so your unit does need new batteries. The whine is usually caused by the charge circuit trying to push the charge to the damaged cells in the battery. You should be able to get replacement batteries from your local battery dealer, no need to order "special" UPS batteries. Open your UPS cover and remove the old battery and bring it to the dealer and they will match it to their stock.
This is just my personal opinion and not the opinion of FixYa or any of it's affiliates. I have never bought anything but APC UPS devices because they simply seem to work better than the rest, especially in the consumer sector. Any company that puts the quality they do in consumer level products simply makes good products, and I would trust them with any size UPS, especially enterprise level.
Try contacting Eaton. They bought Powerware about 6 years ago and the personnel are trained on older Powerware systems. If you have the part number and serial number from the rating label on the UPS, that would be helpful.
I could not find a application support disk, but I assume you are looking for the drivers. Your laptop is made by Medion. I have the same model . I found the sound card drivers here. http://www1.medion.de/downloads/download.pl?id=5561&type=treiber&filename=skwim2140_2170vst.exe&lang=uk
For the rest I used software called “Everest Home Addition” to get the model numbers of each device and googled the drivers for each one.
Right click on task bar, click on properties, start menu, 'customized', 'advanced', scroll down to end of list and you'll see " System Administrative Tools". Select 2nd option "display on the all programs and start menu" and apply or OK all the way out.
Now, from START menu, click on "Administrative Tools" - then "Services" - scroll down to bottom where you'll find "WT SERVICE". Right click and click on "properties". Change 'startup type' from 'automatic' to 'manual' and you can now select 'stop' button. Click ok and your laptop will now stand by. If youor Medion doesn't work you can now turn on the WT service manually.
ok, a combination of hitting keys CTRL (control) and "C" at the same time will make Windows Copy the most recently selected word text or graphics. Then using the combo of CTRL and "V" would paste that into another program. Try this...open Notepad and type the word COPY. Now select that word with mouse drag and then use key combo of CTRL_C. Now open Wordpad (or another notepad) and then use CTRL-V and the word COPY was now pasted into the other program. So the retrieve is the CTRL V combo.
