Common Faults & Maintenance
CMOS/Hibernation Battery Leaks
The T4800CT has an internal NiMH hibernation battery. These batteries are highly prone to leaking, and should be removed on any T4800CT.
Capacitor Failure
Other Toshiba laptops from this time are prone to capacitor failure in their internal DC/DC boards. I have no direct data on this one but I wouldn't doubt that it's affected too.
