Only if your fire and medical insurance is paid up and you know where the nearest fire station and emergency room are. In short, no. --- sam | Sci.Electronics.Repair FAQ Mirror: http://repairfaq.ece.drexel.edu/ Repair | Main Table of Contents: http://repairfaq.ece.drexel.edu/REPAIR/ +Lasers | Sam's Laser FAQ: http://repairfaq.ece.drexel.edu/sam/lasersam.htm | Mirror Sites: http://repairfaq.ece.drexel.edu/REPAIR/F_mirror.html Note: These links are hopefully temporary until we can sort out the excessive traffic on Repairfaq.org.

Repair and replacement of the electronics is a bit more.....trouble. true but most are battery issues Kevin That's not been my experience. When you remove power from the electronics, the battery monitor chip can't be reset without knowing what to do or having the right software. I've managed a couple that used chips that have data sheets. Most have been dismal failures. Good cells that still won't run the computer. If the pack is still alive, some have reported success by wiring up a bunch of power supplies and replacing the cells "hot". mike -- Return address is VALID but some sites block emails with links.
