Got an E420 1141-JDG in May 2012… 18 days later, a bright vertical line appeared on the screen. The line is 2 pixels wide, 3.1 cm long, on the upper left side of the display. After the UEFI upgrade to 8HET41WW(1.23), the problem solved temporarily but reappeared then…


Haven't run any Diagnostics Utilities yet. According to the Hardware Maintenance Manual, the solution is 'LCD assembly'.


Also, noticed the computer doesn’t earth via the power adapter, so connected an earth wire to the USB shield for grounding. No HDD activity indicator, annoying… the pointing stick imprints the screen…


Didn’t let the Iranian guarantee provider to ‘service’ cos they know nothing about the ESD precautions & earthing… they even didn’t know the computers shouldn’t be moved when the HDD is running… informed Lenovo Service in Sweden & China + local IT Union by phone, email, fax & post, no response…


SURPRISINGLY, 2 yrs on, still no new malfunction… have used the computer almost daily… but I’ve been ALWAYS worried about its board failure…
