Lenovo is the latest notebook vendor to fall victim to faulty batteries, and has recalled hundreds of thousands of lithium-ion batteries used in ThinkPad notebooks. 

Although no make or model of battery is immune from some overheating or failure, Lenovo has confirmed that these batteries can be subject to overheating, posing a potential fire hazard, and the company is advising customers to check if they are using one of the affected batteries.
The recalled batteries were sold with or sold separately to be used with the following models of ThinkPad notebook PCs:  T Series (T43, T43p, T60);  X Series (X60, X60s); and R Series (R51e, R52, R60, R60e).
The suspect battery part numbers are as follows:  92P1072 92P1073; 92P1088 92P1089; 92P1142 92P1141; 92P1170 92P1169 or 93P5028; and 92P1174 92P1173 or 93P5030.
Since these batteries work with any T4x Series or R5x Series system, customers who ordered an extra battery or received a replacement battery for any T4x or R5x Series notebook PC between February 2005 and September 2006 may also have a battery subject to recall.
Lenovo estimates that between 5% and 10% of ThinkPad notebooks sold during that period are affected by the recall.
