Dynabook batteries: what the settings and lights mean

eco Charge Mode stops at about 80%

Toshiba and Dynabook laptops have an eco Charge Mode, found in the eco Utility. When it is on, the battery charges to about 80% instead of 100%, which lets it last through more charge cycles. A laptop that stops there is following the setting.

What the battery light is saying

The DC IN/Battery light is amber while the battery charges and white when it is full. Flashing amber means the charge is low and the charger needs connecting. Flashing white means the laptop has detected a fault, and is worth having looked at.

Clip-in packs and built-in batteries

Older Toshiba Satellite and Tecra laptops have a battery pack that unclips from the underside. Current Dynabook models have the battery inside the case, under the base cover, so replacing it means opening the laptop.

Dynabook Battery Replacement — FAQ

Why does my Dynabook or Toshiba stop charging at 80%?

That is eco Charge Mode, a setting that holds the battery at about 80% so it lasts longer. Turn it off to charge fully.

Is the battery covered by my Dynabook warranty?

It depends on the model and its age: laptop makers often cover the battery for a shorter time than the rest of the laptop. Call or bring it in with the serial number and we check your coverage.

Can you get a battery for an older Toshiba laptop?

Often, yes. Batteries for some older Toshiba models are no longer made, so give us the model number, on the label underneath, and we check before you bring it in.

Do you use genuine batteries?

Under warranty, always. Out of warranty, you choose: a genuine Dynabook battery or an aftermarket one. We send you the quote first and start the repair only once you approve it.

Is a swollen battery dangerous?

Yes. Stop charging it and bring it in.
