Question about Symbol LS 4278 Barcode Scanner
The most unlikely scenario is that all the bases are defective. If you power your PC off every night, you should purchase a power supply so the scanners can continuously charge. Another issue may be that you need new batteries (also unlikely if they stopped working at the same time). Also try swapping scanners and bases (one scanner from one base and place it with another base) make sure you firmly place the bottom of the scanner in the base to verify there is a good connection with the charging pins. We are here to help if you have further questions.

Is the cradle connected to the pc via either usb, serial or keyboard wedge?
If so you will need to first, pair the scanner with the cradle by scanning the barcode on the cradle and second, configure the cradle properly so it transmits the data to the host.
Download the product reference guide from motorola website. You will get all the configuration information you need in there.

SOURCE: 3 Beeps after trying to scan
If you are receiving three quick beeps (all the same tone) before a scan the battery is low. If the scanner is more than two years old the battery may need to be reconditioned. It is recommended the battery be reconditioned once a year. The latest revision of the LS4278 manual is here:
Print page 28 of 414 and scan the Battery Recondition barcode. The scanner will discharge the battery then charge it up again. It goes through this two times so you need to leave it on the charger a while for this process to complete. Hopefully this will resolve your issue. If not, you may need a new battery.
If the beeps are low, medium, high the procedure above still may work, but you might want to call Motorola for assistance. Sometimes hearing the beeps helps to diagnose the problem.

SOURCE: I have a symbol LS4278
this seems to be an error with the charging system of the scanner. As you stated the error occurs also with other battery. Just check if the scanner is in warranty and send it for repair.
It could work also with this error, but the charging will not work correctly. As the temperature error is safety measure which stops the charging until the status get changed.

I was also unable to find a solution for you. There are only supposed to be 2-leds in the cradle, 1-green and 1-amber. Maybe it is a battery temp fault, and it has somehow been misread. If you have another docking station and another gun, try swapping them to see where the fault lies. If on the good station the gun shows the same error, you know the fault it with the gun, not the cradle. Hope this has helped!

There are three possibilities I can think of assuming this is not a brand new scanner:
1. The LS4278 is faulty - which given Symbols quality I would say it is normally not the case unless th scanner has been dropped or otherwise damaged.
2. The cradle is not charging the scanner. You may wish to try another cradle - one that you know is charging aother scanner. After a few minutes you should be able to see the laser.
3. The battery in the scanner either needs a recondition (see product reference guide), or needs replacement.
