ES90 ZOOM DID NOT OPERAT - Samsung PL120 Digital Camera

1. use fully charged battery,
2. may be dust inside the lens use an air blower to strike away the dust

There can be more than one reason:
The battery can't be charged anymore, because it is defect.
The cable you use is defect
The charger you use is defect
One or more contacts are dirty or oxidised

Carefully check all contacts on the battery, in the camera the battery compartment but also the USB slot, where the charge cable goes in. The contacts should be clean and shiny. No contact should be bent. Cleaning with a dry cloth or cotton swab.
If the cable to charge is defect it is more difficult to detect. Only when you have another apparatus that can be connecter with the same cable, you could check if your cable is still in working order.
The charging source can be defect.
If it is a charger, you plug in a wall socket, check if you can use it to charge something else. If you put it in a PC, also check if that USB port can deliver 5 volt with enough current.
I do have a little gadget, from the beginning of USB and LED lights. An USB plug with a small cord and a LED light on the end of it.
You could use it as a reading light on a laptop. But it showed very helpful to show if a charger or a USB plug on a computer still is delivering 5 Volts.

I hope you find the culprit.

Success

You may download a copy of the manual from here.

The Samsung ES90 only has about 37MB of built-in memory. The state of the battery has no effect on this. If you want to take more photos then you can either make them smaller, or better yet, add a memory card.

Canons website should have the manual available for download.
