HTC Dream keeps on showing power options screen I have an HTC Dream cell phone which was working fine till last night. Today morning I woke up to find that the cell phone battery had completely discharged. So, I replaced the battery with an extra one. 

I powered on the cell phone and I am surprised to find the "power options" screen turn up every few seconds. Pressing any button also makes the "power options" screen turn up. I tried resetting the cell phone to factory settings. I even tried a hard reset but still this problem persists. Any idea how I could solve the problem?

Thanks in advance.
If you're running a stock ROM, I suggest you root the phone (the warranty's way gone) and upgrade it to CyanogenMod 4 (Android 1.6) or CyanogenMod 6 (Android 2.2).

Battery life is very good on 4; 6 is more recent version of Android -- however there are some additional hoops to jump through to get it installed.

The first step in most Dream rooting instructions is to downgrade it to a vulnerable version, so you will lose data stored on the phone. You might have luck with one of the "one-click root" programs but if you can't kill the "Power Options" dialog every few seconds, you may just need to flash it with the RC29 DREAIMG.NBH.
