Toyota Repair: 2006 Tundra Crew Cab 4wd SR5 50K miles, gear indicator, dealer option

Question
Its an automatic with factory alarm,no remote start but keyless entry.  the alarm just started going off one day I would reset it and again 20 minutes later it was going off.  The 2nd time I entered the vehicle , keys in my hand and I noticed the blower was on. I then turned the car on & off when I removed the key I noticed the gear indicator light was still on.  cycled the vehicle off and on every thing turned off that time.  Next day battery was dead or the immobilize was triggered took less then 1 minute to charge battery enough..  I thought my alarm system is draining the battery the only thing I could do was disarm horn and buzzers.  The system still drained I now turn all accessories off and don't arm the alarm.  the gremlin resurfaced the head lights remained on even though switch is in off position THE LIGHT would turn off if switched to on position once are start and turn off the vehicle the switch operates properly!!!!  what the hell is up with this electrical system ( the day this started I had my  fujitsu lap top in the vehicle I believe the tundras keyless system is also fujitsu is possible they are interfering when the lap top searches for wireless portals?

Answer
This is a little too involved for me to try to help with, it seems there is an electrical problem but you already know that, there may be an issue with an aftermarket accessory that was installed and there may be a wiring problem, at this time, other than the lap top I don't have a way of knowing what else was installed but regardless I would recommend to you to take the truck in to the toyota dealer since it may still be within the 36,000 mile warranty period. It's not just an alarm issue, the blower being on and the gear indicator light indicates that something was changed in the wiring of this truck, I assume you have checked all the fuses, even though I don't think that's the problem you could do that before resorting to the dealer option.
