1998 Volvo S70 All Warning Lights Always On

The battery in my 1998 Volvo S70 completely died over the winter. It is a brand new, good quality battery purchased late last August, but I didn't start the car over the winter and the battery drained out. I tried to jump start it with another car, that didn't work. I called AAA and they came out and used one of those high powered battery jumper things and got it started. I was told to leave the car running for 25 minutes. After letting the engine run in park for 26 minutes, I drove it to the gas station, turned off the motor and put in $10 worth of gas. Everything was working fine, except. My dashboard light was out (I thought the AAA guy had turned if off and I didn't know yet how to turn it back on). The other thing was my fuel gauge (before I put the $10 of gas in) was going from a little over 1/4 of a tank down to Empty and then going back and forth between showing a level of gas and being on empty (but the empty warning light was not coming on). I drove back home and parked it. The next day I started the car, and after the car was running EVERY one of the warning indicator lights stayed on. AND. The gauges for speed (speedometer), the RPM gauge, and the fuel gauge were all not working and sitting at zero. The odometer (that thing that can't be reset to zero. Not the trip meter), was reset to ZERO. The trip meter and clock were working normally and maintained the setting from the previous day. But the Temperature (climate temperature) that shows up next to the clock on the dash was not working. Just four dashes are showing, the previous day it registered the climate temperature. Everything else seems to be working fine.(Still no dashboard light though). The electric seats, seat warmers, electric locks & windows, sunroof, headlights, indoor & trunk lights. All that is working. The radio is not working but that is because it needs the code put back in and I haven't done it, but if I turn it on the antennae comes up and the radio lights up and asks for the code. After driving the car approximately 4 miles, the lights were still lit up. I left the engine running in park for an additional 30 minutes before shutting it off. Anyone have any ideas what is going on?

If I put the key in the ignition in the 1st position. The only light that comes on is the SRS light, and it goes off after some seconds.

With the key in position 2 "on" engine not started, ALL the warning lights come on and stay on.

With the engine running, 3 warning lights on the right side go off (the 2 on the far left of the top row, and the first light on the far left of the bottom row) but all the other lights stay on.

The battery seems to be recharged as the car starts with no problems for 3 days now.
Though the rpm gauge does not work, I tried revving it to approximately 4000 rpms, it made no difference.
