X220 brain surgury

2018-06-18, 18:18 PM

looking at the service manual, I see the CPU I own (i5-2520m) is a socket G2 part. So I was looking down my pointed little nose at brain surgury given the CPU is in a socket.

 

Sandy Bridge is what I have now but I was looking at a possible Ivy Bridge processor but I was not sure if the BIOS can see such processors properly or not.

 

I own: T400 T500 X220 running Windows 10 x64 & My X230 runs Linux for my webserver. I also own an Apple MacBook along with an iPad Pro 12.9", both with 256GB SSD

x220 has a soldered CPU, not a socketed one.

so much for that idea :(

 

guess the SSD and more RAM are the only options........

 

stuffed a ac533 card in the machine which is a universe batter than the OEM crap it came with

 

found an adapter that can allow NGFF cards to be installed so maybe I can get an ax2900 card in the machine next year

hey mate

 

tjust a few tips you that would go a long way on your x220 journey

 

- all X series and Tseries with  a lower case s models (such as the T420s vs the stock T420) are soldered/bga

 

in some cases these s series wil also come with a single slot ram with soldered ram alrdy on the mainboard

 

-i'm not too sure what an ax2900 is but this will probably enable you to decide if your next move is plausible

 

the msata slot on the sandy and ivy bridge series are SATA 2 based. they can be run as a boot disk and with SSD on SATA 2 - realworld speed is still not an issue.

 

the ivy bridge series sets the standard on the current ketboard that is produced on the thinkpad series & is often quoted as best in calss.

 

having used both - the older gen version which is last seen in the sandy bridge llne are the best imo..

 

with the price of ram being low - the best use of you r cash is an ips screen, a 128gb msata and keep the provided 320gb storage where it is.

 

p.s. worth noting that if you manage to obtain the i7 version of the x220 you have then the holy grail as it comes with a USB 3 port.

 

you can of course use your expresscard to hypothetically obtain the same but none of them works without any form of constant troubleshooting.

 

and lastly -the x220 allows use with 3rd party battery sellers so pls buy a premium battery pack from a trustable seller.

 

 

last i checked - the ones i got with samsung or sanyo cells were still $50 cheaper than the lenovo rrp

 

as the only weakness of a mobile tech is the gradual degradation of its power source and of course the lack of that specific oem replacement is why most consumers continue to buy new laptop.

 

this machine runs windows 10 without somuch as a hiccup.

I have a fixed BIOS so no whitelist issues for batteries or any other field replaceable hardware.

 

802.11ax will be 4x faster than 802.11ac so I ordered up an NGFF adapter so I can use the newer model cards.

 

My i5 motherboard is PCI Express 2.0 based so my ExpressCard can handle a USB 3.0 card I own but I do find the power provided to be an issue with a hard disk. I use a 90W PSU so I guess there is not enough 5V to go around?

 

My machine has 2 easy access and not soldered RAM sticks so I can install anything I can afford.

 

Now that other slot inside the machine has use for a SSD or a LTE card. I wonder if that can handle a modern SSD with an adapter?

 

I have a SATA SSD installed now in place of the OEM hard disk, 480GB SSD is bigger than the origial hard disk.

the 90w psu provided is plenty as it usually only comes with the dock while the laptop alone operates on the 65w stock psu.

 

your issue on the 5w via expresscard is due to how the schema is designed. put bluntly - the expresscard to usb 3.0 is a not a natural conversion.

 

i believe there was a very indepth thread on this in reddit comparing the cheap expresscard usb converters available - its a useful resource as there will no longer be any further development on this due to the lack of demand and supply.

 

the adapter card is quite ingeniuos as it supports both pcie and sata for less than $5 but i would suggest adding a zif extender as the layout of the minipcie slot for intended for the wifi card is designed to fit the form factor of a half sized mSATA SSD or a typical mpcie wifi card size with not much wriggle room whilst the adaptor you linked looks larger.

 

Its doable imo - by either not using the opposing mSATA slot or by buying an additional extender kit. the extraspace can then come from the other side of the palm rest where the expresscard resides

 

let me know how you go.

 

if you have trouble understanding what i just said - pls refer to the drawings of the model to google the X220 teardown to get a better visualization of this.

Re: X220 brain surgury

I dug around on eBay extensively and I have identified brackets and adapters to install NGFF Wi-Fi so at least my internet connection wll be solid.

 

I installed a Realtek 8821AE 802.11ac card and the performance compared to the OEM is dramatic. The Intel Centrino N1000 is a n300 card but it had very poor RSSI compared to the 8821AE.

 

There are lots of mSATA SSD drives up to 1TB availale so an adapter is not critical. M.2 8846 will fit the X220 but longer SSD drvies crash into the drive bay. Sadly nobody though about longer SSD cards when the X220 was designed.

 

One of the motivations with the NGFF adapter is that Bluetooth 5 is now available. The internal one is disabled now, I cannot remove it as the BIOS is unable to cope, whitelist is not the only headache with the X220 ROMs. Windows 10 at least maiantains a device as dsiabled with reboot, used to have to real problems with Windows 7 which is what my machine originally came with.

 

So it looks like the biggest SSD I can install is 1TB which is not bad, and then I can use a hard disk or iTunes etc. I believe 7mm disks top out at 2TB at the moment, but I am not sure of 9.5mm thich hard disks will fit.

 

I can still use M.2 SSD as there are SATA boxes with a slot so I can bulldozer the problem of capacity, the SSD box had 2 slots so it has some additionall potential over the mSATA slot.

hey bud - i think you need to take it real slow

 

any AC card would be better than the stock - we are talking about 5-6 years of tech diff here

 

you could have avoided the adaptor if you were happy with an AC wifi card which the intel 7260 that can be bought for less than $20 in the mini express form factor

 

fyi BT 5.0 is not even supported by windows 10 yet. I believe 4.1 is the current threshold.

 

 

there's already a 2 tb ssd called the sandisk cloudspeed which has been around since 2015 and performance wise -is right up there while the price has come down a lot. It's a 7mm form factor but mind you powerconsumption is a bit above the norm given it's primary use.

 

If you add that to a 1tb MSATA ssd you'd have a freakshow.

 

oh and btw - remove the bluetooth daughtercard (the old one) and turn on the WWAN which in turn would enable your Realtek's BT to work.

 

you should have no issues as long as you enable the WWAN and also the infamous tape on pin 51

I tried removing the BT daughter board and that borked the Wi-Fi card's bluetooth.

 

Not sure what setting I need to be able to get rid of it and use the one on more modern integrated hardware.

 

Bluetooth 5 is supported by Wndows 10 but this assumes you have version 1803 installed.

 

I found a 256GB mSATA card from the same vendor as I bougt some RAM from. Maybe I will get that unit as it is big enough for Windows and Microsoft Office etc.

 

Then I can installa big fat hard disk for iTunes. I have a USB DVD drive so I am not hard up for an optical disk. I wonder if there is a dock with an optical disk on it?

There is, look for Ultrabase Series 3 or FRU 0A33932
