The 16gb of ram in my t520 really isn't cutting it anymore (thanks firefox!). Looking at upgrade options. I like the modular Framework laptop. But it seems really too thin and hindered by thermals to ever be a true "beast". Plus they are running out of stock right now and getting backlogged. So that...

Now the plot really thickens. After having a completely dead battery for 2 days, it just now decided to start charging... Really weird. In other news I was looking schematics most of the evening for fun. Looking at the similar x201 schematic: http://plan9.stanleylieber.com/hardware/thinkpad/x201/x2...

Yes, those pipes are filled with 'juice', see https://en.wikipedia.org/wiki/Heat_pipe Yea, I went ahead and cut the one off I didn't need, sprayed out the inside with electronic cleaner, and put a little JB-Weld over the opening 8) For those interested in my handy work: The cutting was easy..but we...

It could also be some power saving settings, the OS might be turning it off randomly to save power. Try setting the power management settings to "max performance" or something similar. Its a common problem with wlan cards, never seen the issue with ethernet though

I've discovered over here http://forum.thinkpads.com/viewtopic.ph ... 26#p781290 two reports (three if you count me) of people having charging issues that resolved itself magically after a few days.
So maybe there's hope

I have a replacement 'used' battery on the way. I also went ahead and bought an oem 6 cell off of amazon. The problem is I go out of town for a week for the US python conference. Really need to have a working battery and I am out of time. I have another motherboard I can try, but I am not convinced ...

Oh also forgot to add that while digging through all the battery stats under '/sys/devices/platform/smapi/BAT0/' (at least in linux world) that there is one called "remaining_percent_error" I have no idea what that is. The docs just state that it is the estimated error of the remaining_percent. Gog...

I should add that I got my new 'used' battery in the mail today but it just gave an orange flashing battery led and all the stats for it are 'undefined'

So I decided last night to go ahead and try to discharge the battery as much as possible in order to maybe 'calibrate' it since it was now charging. Figured since I had another battery on the way and another motherboard that I'd throw it through the works and really make sure its working. With prime...

Hmm weird. I noticed earlier that the current battery charge percent had "increased" from 36% to 37%. Figured maybe it just crept up from sitting. Charge current was 0 at the time. But then a few hours later I noticed it was at 54%. The battery state was 'idle' instead of charging. Unplugging from A...

the battery from your t61 should be electrically compatible with the t520's one, try to line up either battery with either laptop, see if it works. this document suggests that they are electrically compatible, https://support.lenovo.com/eg/en/documents/ht037009 your problem IMO sounds like a mother...

Tried booting into windows and using the normal lenovo power manager tools to see if that would get the battery charging. No dice. The stats say the same thing as in linux, charging but the current rate is always 0. I wasn't able to rig the old mother board up into a state where it could charge a ba...

So the swap went alright, took all saturday though. There were a couple of surprises. I'll post some pics and talk about those in another post. But the issue right now is the battery is not charging :( Everything was fine after the swap and I used it until battery was down to about 40%. I plugged it...

My T520 and Mini Dock Plus Series 3 has this problem too. I see there is another docking station available the "Mini Dock Series 3" (non-plus). It has the audio plugs on the back instead of the side. Does anyone have this one and can confirm if it has the same issue? Thinking about buying it to see....

The only other issue I can think of would be fitting my current heatsink to the non nvidia board. The board with nvidia: http://tinyurl.com/hhtqy63 The board without: http://tinyurl.com/j3s7gus Everything seems like it should line up, hole-wise. But to the left of the cpu socket on the board with nv...

I just bought a lightly used T520 with i7 quad core cpu from ebay this week. This was an upgrade from my T61 that had just gotten too sluggish and lacks the ram for what I use it for (software development projects with Linux as the OS) So far the T520 is awesome. I had no need for the dedicated nvid...

For fans with a normal sleeve bearing (I've never had to oil a ball bearing fan), I've always had good luck with black automotive grease. If you don't have any of that around, then use motor oil (even if you have to steal a drop from your car's dipstick). All of the lubes that come in a spray can I'...
