Re: Project result report: Re-celling 8-cell X6x (non-tablet) battery

When the battery reports 0% the laptop still works for several hours. Huh, interesting. I actually experienced the exact same thing. From having changed the capacity in the EEPROM, I know that the controller can decrease the "known" capacity by 10-20% per charge cycle, but that still doesn't explai...

Project result report: Re-celling 8-cell X6x (non-tablet) battery

Hi all- Figured this was worth at least putting in its own post. I recently decided that I would try to re-cell my 4 & 8 cell X61 batteries; both of which were degraded to the point of complete uselessness. Here's a short & quick summary of what I did and the results. Feel free to ask for details on...

Re: how to revive a destroyed li-ion battery due to overdischarg

I did succeed, but it's probably worth starting a new thread so I can write up a proper report. Stay tuned!

EDIT: Thanks for the tip, I didn't check that before I recelled. I got lucky and had UR18650FMs, which charge to 4.2V *phew*.

Re: How many of you have already got the X62? And any new interest?

Sadly, no. He's probably talking about that 3D printed piece that covers where the dock connector is SUPPOSED to be.

The one I printed off doesn't fit very well either, I believe you line up the oval hole and sort of squish it in... that more or less did the trick for me.

In fact, it's the same plug that the fingerprint reader in the X61t lid uses, it was just discussed over on the German forum where someone used it to hide a small internal hub / mouse transmitter

Re: X62 problems, quirks, and fixes

With the spare internal USB port, you can probably fit one of those WWAN-Adapter things next to the sound board and have both.
Seems to lack a 2nd true mPCIe lane though, which is sad.

I almost want to say "challenge accepted".

That's basically the only reason I'm ...

Re: 801.11ac Wireless Card?

My usual recommendation is the Azurewave AW-CE123H. Cheap, half size, BT4 + 802.11ac. And also compatible with Hackintoshes, if you care.
It has served me very well and I like it, but since I don't have any AC network to test with I can't really comment on its performance in that department.

Anyone know how to turn OFF the internal LCD from boot when an external screen is attached?
I don't see any BIOS options to that effect, but maybe I'm missing something. I'm thinking of the old "LCD", "External" or "both" selection.

Disabled everything I can think of / see and removed all storage devices except the mSATA drive; no change. I wouldn't even know how to tell what the machine is doing, but it takes almost exactly 17 seconds before the X62 boot splash shows up.

One observation and one comment on how I might have broken the BIOS initially. - First, it now takes around 17 seconds for the boot splash to even appear. I don't recall this being the case before, is there a common explanation for this? The machine works again overall so that's great, but 15 or so ...
