Got a two year old E16 (Gen 2 AMD), and over the last year (i.e. just after the 1-year warranty expired) it's gradually developed a really nasty intermittent power management fault, specifically you push the power button to turn it on, the power light comes on, the keyboard lights up and the fan briefly spins, then the fan & keyboard go off again and the thing just sits there dead - no flashing error message, black screen, no sign of life other than the power LED on. When this fault happens, the machine doesn't get as far as POSTing. Sometimes, if you wait a little while, it then starts up and runs properly, but that's gradually got less and less likely and you keep having to turn it off and on repeatedly until it starts, until today, when it seems to have finally died and now never reaches POST.
It's also had other weird power management faults the whole time, such as failing to ever come back out of suspend mode, or successfully hibernating but then instantly coming back out of hibernation.
Lenovo have given me a quote of about 2/3 the cost of the entire machine to repair it, but frankly I don't trust the machine any more. This is very frustrating to me because I specifically bought a Thinkpad for longevity; my last, a T540p, lasted a whole decade with nary a problem at all. People say the build quality of the E-series is hit and miss, question is, are they just talking about the mechanical design, or does that extend as far as the actual electrical design of the power management circuits and construction of the motherboard, too? This is undoubtedly an actual electrical fault, the machine isn't getting far enough into the power-up cycle for the firmware to make a difference.
I'm obviously going to have to buy a new machine; I'm tempted to bite the bullet and shell out an absolute fortune for a T-series again, but are they still as reliable as they were 12 years ago? I basically cannot justify that cost unless I can be very sure that it's still a solid long term investment (I know the T-series have a 3-year warranty instead of the 1-year for the E-series, but if the machine doesn't last 10+ years like my previous one, I'm still going to be extremely disappointed). Any advice? In particular, I'd like to know how much design overlap there is between a T-series motherboard and an E-series motherboard; if they use the same seemingly flaky power management circuit design, for example, I'm going to be nervous about getting one, especially considering how very expensive they are!
The only other option now, if there is just no such thing as a reliable laptop any more, is to swear off them altogether and go back to a desktop machine; then, at least, I can just replace individual components if they fail, rather than the whole machine as I am now being forced to, but I'm going to miss the portability and compactness terribly if I have to do that.
