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

I see that both you and this thread are still active, so if you don't mind a few questions: -How did you go about opening the battery? I've gone over the entire seam around it but can't find the bit that either clips or glues it all closed. -Did you transplant by connecting the new set in parallel,...

Re: Upgrading X220/X230 to FHD 1080p

Hi, I have received the board from the 3rd batch and the display also has arrived last week. The board is rev.5. I'm missing the installation guides for rev.5 boards. Or, How the installation differs from the board rev.4 to the rev.5 ? rev.4 boards have a different pad to solder the aux. power wire...

Re: Upgrading X220/X230 to FHD 1080p

Thanks. How much does one loose in battery life if he's lazy and doesn't apply the kernel patch? I haven't noticed any power consumption difference with and without the kernel patch. I suppose the patch only influences what screens are visible to user. I like the patch because without it some displ...

Re: Check RAM voltage?

And I also have DDR3L modules installed in my x230 and they are working just fine. What I meant by saying "x230 supports only 1.5v RAM" is that it will run RAM with 1.5v. And as DDR3L backward compatible with DDR3 (it can work with 1.35v as well as with 1.5v) it will work just fine in DDR3 slot but ...

Re: Check RAM voltage?

I've just checked dmidecode output on my x230 and it also doesn't show voltages.
And my x230 has a stock bios.
So, it seems like x230 doesn't provide RAM voltage information.

Re: Check RAM voltage?

Hi,

You can try dmidecode.
It shows voltages on my machine:

Code: Select all

        Minimum Voltage: 1.5 V
        Maximum Voltage: 1.5 V
        Configured Voltage: 1.5 V
But I'm pretty sure x220 and x230 support only 1.5v RAM.

Is Chinese battery bad?

Hi All, I needed a new battery for my thinkpad x230 and decided to buy a replacement battery from Aliexpress. There're rumors that cheap Chinese batteries will not last nearly as long as the original ones but I decided to give it a try. After I received my battery I did a couple of cycles and checke...

I'm going to tweak pre-order procedure a little bit.
What should do those of us who had made a pre-order?
Will you send pre-payment instructions?
It would be really nice to have some sort of pre-order tracking :) I mean to know how far you on the list :)

Current: 84.33Wh, that is MORE than original design, after almost 7 years of use!
That is incredible result!
Did you use some techniques to prolong battery life? (like limit full charge using charge thresholds)

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

Thanks for sharing your experience! I also repacked my battery for x230. But when I did it I didn't know that it is possible to reprogram a controller. So, I did a cells "transplantation" without powering off the controller. The controller didn't lock up and the battery was working fine. Next I trie...

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

I recently tried out that approach, it works for the packs I Iooked at. I reset the cycle count and capacity to see what happens; it does work. I then ordered a couple ncr18650ga to replace the old cells. Now waiting for snail mail. R Hi flyingfishfinger, Did you manage to rebuild the battery? Ther...

Re: Upgrading X220/X230 to FHD 1080p

When is the kit expected to be available to order?
I'am eager to buy a panel but couldn't find any information when a new batch of kits is going to be ready.

Thanks.

Hi All, Just came across this mod and, as everybody else, want to buy the kit :) @nitrocaster will you produce kits from batch2 (with sense wire) for those who feel confident with soldering it? I tried to read both threads about this mod and couldn't find more detailed information how the converter ...
