I have worked with Lenovo ThinkPad machines for over 11 years and have to say in my opinion they are the most reliable and solid business class machines. I've worked for many companies including IBM & I work on quality not quantity All the laptops are available via my website thinkpadmike.com and also via my eBay store www.ebay.co.uk/usr/thinkpadmike, you will see its slightly cheaper to buy direct via my website due to the lower selling fees involved.
All laptops are thoroughly cleaned, tested & have the fan checked and cleaned and some if applicable will also have new thermal paste applied to the heatsink this will be mentioned in the listing. Each machine is left to run for a minimum of 24 hours without been aloud to sleep or hibernate to see if any issues arise plus a clear diagnostic scan. I always aim to be honest & point out any cosmetic defects both in the description, pictures and integrated video. All my laptops are covered by eBay's 30 day money back guarantee
