#216 — "RTC battery is low..." Toshiba TECRA A8 (Satellite Pro A120)

When powering up my 4-year-old Toshiba  today, the warning "RTC battery
is low..." came up; first time it has ever done that.

According to the handbook, the Real Time Clock battery does recharge
when the power is 'on'; charge time 8 hours.

Although the laptop has not been used for 2 weeks, in the period up to
then it was powered up (wih mains connection) for at least 8 hours
each day for 3 days.

Presumably this indicates the Ni-MH RTC battery is failing.
Is this typical after 4 years?

	There's no really "typical" time.  They do wear out.  It's a cheap
fix.

  Could be, but here are no clues in the user manual as to the whereabouts of
the RTC NiMH battery, or its type/rating.

All the user manual says is:

  "It ... should be replaced only by your dealer or by a Toshiba service
representative."

Googling Groups showed the following for a similar Tecra laptop:

"Unfortunately it is not easy to replace the RTC (CMOS) battery in a Toshiba
Tecra 9100 laptop. In order to replace the battery you will have to take it
apart and remove the top cover assembly. The RTC battery is connected to the
power board. It’s really hard to see the battery on this photo, but it’s there.
You can find a new RTC battery for this model if you search on the Internet by
the following part number: P000328540"

Seems have to dismantle the laptop, so I may not go down that path...
