Based on advice from several on the List, I re-installed the 10.2.6 Combo update over my 10.2.6 that had been incrementally updated (the primary purpose of that was to see if it improved the stability of M$T Word X, which it might have done, slightly). What I have noticed however is that with the 10.2.6 Combo update is that I get the low battery warning notification at 8% of battery power remaining. On 25 April, I posted that: my Ti-500 (Rev A) with 10.2.5 gives no low battery warning, just suddenly shuts down. Was this fixed in 10.2.6 or only in the Combo update (I cannot tell anymore)? Anyway, I am glad it is back! Trevor
