My laptop was in storage for about 6 months while I was waiting to move house. When I went to use it again the battery (lithium ion) was completely dead and wouldn't re-charge. Does anyone out there know if there is any way to revive it, or will I have to stump up the £100+ for a new one. I hardly ever used the battery and the computer is now only about 18 months old.
Some lithium-ion batteries fail due to excessive low discharge. If discharged below 2.5 volts per cell, the internal safety circuit opens and the battery appears dead. A charge with the original charger is no longer possible. Some battery analyzers (Cadex) feature a boost function that reactivates the protection circuit of a failed battery and enables a recharge.
