Mainly it seems that Lenovo had some bad luck with third party EEPROM chips used in Think and Idea models made between September and December of 2011. A person posted this as being an official announcement:
Now I live in a country where I can only grab a ThinkPad from a retailer, who doesn't offer more than one year of warranty and they say that the current batch of ThinkPads they got were delivered just a few months back, but I insisted they check the manufacture date and they said that they have been manufactured on the 25th of December 2011 (apparently some stickers show 3 digit dates?) but either way if the numbers in question are 11/12 no way it's november 2012, so it has to be december 2011.Lenovo has identified an issue which affects a portion of Think and Idea systems that were manufactured between September and December 2011. The issue manifests as early life failures of the EEPROM chip and results in the system failing to power on or boot up. Not all of the systems manufactured during this period of time are affected. This is an industry component issue and is not limited to Lenovo. The solution is to replace the system board.
So, my questions are:
How accurate and how widespread is/was this problem with EEPROMS in ThinkPads?
Has Lenovo fixed/withdrawn the faulty models after they have concluded it is an actual problem?
If the ThinkPads that are for sale here are indeed manufactured towards the end of December 2011 how likely is it that they could be part of the faulty series?
If so should I still consider getting one, or is the risk too great?
What I'm most appalled by is getting an E520 that fails to power on (dies) just after the warranty expires (the retailer here does not offer a warranty extension above that 12 month one).
Please, any answers and/or additional info would be extremely helpful. I really want to get a ThinkPad for my budget, but after reading all that I started doubting whether I should risk it.
