P50's dying. No power

[quantiq]

Hi all.

We have bought five P50's with 32gig RAM, 1TB HDD with the 6820 processor.

So far two have died in the space of a month.

By died I mean dead, will not power on at all, no power lights, Zip. Tried everything and had to get Lenovo out and both times the motherboard has had to be replaced.

Is there a known issue with the P50's? Or have we just been very unlucky that 40% of our P50's lasted less than four weeks?

Any opinions would be great thank you before we go back to Dell and scrap Lenovo.

If they died that quick I would also check your outlets that they are connected to, perhaps they are getting slowly surged? Did they die primarily when recharging or out in the field?

Yes, those look like fried Mother Boards, perhaps, because of a power spike. Did you ask the Lenovo Tech what was the problem? It looks like replacing a motherboard is to Lenovo Techs what pressing Ctrl+Alt+Del is to Microsoft support reps (although, a lot more expensive answer)

These days, product testing is highly automated. Every single laptop should be tested for Software and Hardware performance, within its specified parameters. So, even if we may not agree with the apparent quality of a particular product (which may be related to quality or manufacturing tolerances that have become too loose over time; but I digress) it's highly unlikely that you'll get a completely broken Mother Board, let alone two in a row.

My engineering workgroup uses several dozen Thinkpads. Mostly T460's and several P50's.

I received my P50 last August. The only issue I've had has been intermittent failure of the HDMI port (very popular thread on this forum; and a problem which I solved by buying a mDP => DVI cable). I haven't heard of any complains from anybody regarding hardware problems with their Thinkpads. There's also an internal computer blog, to which I subscribe, and most of people's complains are Software related (Windows / Office). There are very few Hardware related complains and none that required a MoBo change.

It looks like Lenovo always-beta-stage BIOS stuck issue.

My P50 (Win7, 16GB RAM, 1TB combined storage, i7-6820hq) has been great.
Make sure you have adequate cooling, and consider purchasing a cooling pad or mat for your laptops, especially if you are doing GPU/CPU intensive work for hours on end.

Have you checked to make sure that you are not putting your laptops (or having the laptop put itself) into Airplane mode? Because in Airplane mode, the laptop will not draw more than 80 or 90W, and won't charge or power-on if it is supplied with less than 100W (or something weird like that--I don't exactly recall).
