From a, t, x series began , tp laptop charging mechanisms have become more intelligent. Usually , over time , the notebook 's power will automatically discharge , tp notebook only when the battery is less than 95% will be charged automatically . So you do not have to worry about when to use it normally will automatically be charged, which is much better than the previous 600 series . Over the past year, more than a t20 Practice has proved that the charging mechanism t series is completely dependent . Do not worry about the battery overcharge issue.

Charging process

a, t, x series when charging , the charger will first fast charging , then switched diode display ( ie, first left ) is yellow ; charge to 80 % of the time into a slow trickle charge current , where the diode the color becomes flashing green ; since been filled with 100% , it becomes a normal steady green . Lithium battery charging process is constant voltage to start charging soon that will stabilize the voltage and the current is getting smaller and smaller .

. . ibm numbering rules

If t23-5ku-78-cywwv, explained : it belongs to t23 series 2647 are models (machine type), 5ku is a model (model), the last letter on behalf of other exclusive range of markets , known to have c Chinese mainland , h Hong Kong , t Taiwan , a Southeast Asia ( such as Malaysia , Vietnam, Singapore , etc. ), u United States , j Japan , etc. ; last 7 or 12 is the serial number of the fuselage . But I do not understand how will compile ibm so complicated it is.
