T43p SATA Guide (There are pictures, it's 2020)

[berrieds]

Hello everybody,

I've registered an account just to try and ask a few questions specifically regarding this mobo mod.

I've recently purchased a really lovely T43p. Of course, I want to do the mod in order to make it live up to its full potential. I've got a lot of experience taking apart older TP 770's, which is a real toughy compared with taking apart the T43p.

I've read through a lot of posts online, so I'm ready to get started. I've bought as many of the necessary components as I can, but it is the procedures that are still a little confusing.

Has the HD LED light been definitely solved (i.e. working), and what is the preferred method for getting that running?

Do things like TRIM work with the SSD the way they should?

Specifically regarding a few materials... I've never really done much soldering. What type of solder do I need to use? What wires, or wire should I use/buy to make things easier? I have the SATA connector, so hopefully I can easily plug the drive in using bay as designed.

I'll have more questions as I go along, but it would be nice to get any feedback before I make any potential mistakes.

Cheers

Welcome to the forum.
For HD-LED wiring, see page 4, the rest is all fully described on page 5 of this thread.

Hello again,

The confusing thing about the HDD led connection for me is the connection to the old IDE connector, pin 39 - where is that getting the signal from? That's the 'Activity' Pin as described in the IDE layout, but do I have to connect it to something on the SATA connector?

The University of Manchester have an Electronic hobby club on Wednesday afternoons that I'm planning to get most of the work done at. They have an infra-red solder rework station!!! Even still, I fashioned a metal shield from the bottom of a tin can just to be on the safe side

[RealBlackStuff]

That one wire between pin 39 and the chip-bottom is all you need.
It's apparently the AUX_ON signal going to AUXPWRG on the docking connector.
Don't ask me how or why.

[berrieds]

I decided to have a look at Intel's datasheet for the SATALED#. section 5.17.5 p.~190 it says, "When SATALED# is low, the LED should be active. When SATALED# is high, the LED should be inactive."

I speculate that IDE pin-39 detects the change voltage with the adjacent 5v pin-40, thus when the HDD/SSD in inactive, the signal is high, and when it is drawing current the signal from pin-39 will be low.


Here's how the chip removal went

It looks like you went a little too far with the HD-connector removal.
I'm missing the two solid pins that hold the black plastic connector-housing.
You'll need those pins again for mounting the SATA connector.
I put these 3.5mm (1/8") high glass beads between motherboard and SATA-connector, to give it the proper height.
http://www.firemountaingems.com/search/ ... h20-2647sb
That way a SATA-drive always fits in perfectly.

[berrieds]

Yeah, that was a mistake Only after re-reading the thread did I see the remark that these should be left in place. I was just looking at PCB through-hole pins to connect up the SATA connector with the mobo.

Another issue I had was that the connector I bought, which I think is identical to the HP AT368 suggested in this thread without the P/N stamped on it, was too long. I read that someone else had this same issue, so I've pretty much the same thing which is to drill a new hole in the long-arm to which I'll attempt to epoxy the nut in line with the PCB hole.

Thanks for the information though, I was just trying to find out how high I needed to mount the connector, and generally there isn't much information available. Had a quick look on Ebay and ordered some of the same brand beads. Once I find some through-hole pins to mount the connector, I think I'll be good to go with the rest of it.

[RealBlackStuff]

Leave the short-arm as-is, drill a new hole in the long-arm, exactly 45mm from that short-arm hole, then shorten only the long-arm, so that the total connector length is 49mm.
Don't worry about the nut you remove from the long-arm.
Mount the connector with the short-arm to the front of the motherboard.
The new drive goes also in upside-down (label to the table), like before.

When finished the connector-contacts on the POWER-side should be like this:
12V..xxx..5V..gnd.3.3V.....x..B+B-..x..A+A-.x
/|\..|||../|\../|\../|\.....|..|..|..|..|..|..|

(where /|\ means: solder together, and x means: leave it)

You only connect to 5V and gnd, as well as the B and A contacts.

[berrieds]

I did wonder about everything being upside down, but I figured it would work out if I didn't ask too many questions

One suggestion I got from the the guy running the guy running the hobby club at the university was to solder each of the gnd connectors on the power-side to separate gnd IDE pins. I believe this was to give a level of safety/redundancy, rather than just having a single gnd.

Regarding the data connectors, I was a little confused because Mike's blog gave this information for wiring the 88SA8040 pads: http://mikejmoffitt.com/sata/mahvel_baby.png

This suggests that:
32 (TX_P) -> PIN 6, B+ (Receive +ve)
31 (TX_M) -> PIN 5, B- (Receive -ve)
-
-
28 (RX_M) -> Pin 3 A+ (Transmit -ve)
27 (RX_P) -> Pin 2, A- (Transmit +ve)

However, reading over the start of this thread you gave the opposite configuration:

For those of you who have been looking everywhere (and I mean EVERYwhere), here is the pinout of the Marvel 88SA8040:



The pins that we need are:
27 RX_P = Receiver POS (your B+)
28 RX_M = Receiver NEG (your B-)

32 TX_P = Transmitter POS (your A+)
31 TX_M = Transmitter NEG (your A-)

Correct me if I'm wrong.

When you look at the big black chip on the picture in Bibin's second post, where it says:
Marvell
88SA8040
Pin 1 is on the bottom left, then goes to the right, then up, then left, and then down.

63............................................ 18
64............................................ 17
...1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16

This left me unsure of whether I should connect receive to transmit, or connect like-to-like... Obviously I don't want to screw this bit up. From others' photos I seemed that 32->B+ but I thought it would probably be best to clarify the matter.

Thanks you ever so much for the information you've given so far, especially with regards to measurements that I would not have been able to work out (or just guess at) otherwise. I can feel this all becoming a lot clearer, the steps seeming more straightforward, although I probably won't be able to get it all done for another few weeks. You've been a great help

[berrieds]

Here's how the connector looks after a bit of shortening and epoxy:

http://miasmcr.x10host.com/UpgradeProgr ... ormod1.jpg

http://miasmcr.x10host.com/UpgradeProgr ... ormod2.jpg

After testing it all fits I've liberally applied epoxy to reinforce the whole thing.

[RealBlackStuff]

Oops:

http://forum.thinkpads.com/viewtopic.ph ... 07#p617507

The pins that we need are:
27 RX_P = Receiver POS (your A+)
28 RX_M = Receiver NEG (your A-)

32 TX_P = Transmitter POS (your B+)
31 TX_M = Transmitter NEG (your B-)

EDIT: 20 December 2015: finally corrected the above...

All those years I never (re)read my old post.
AFAIK the original Bibin-data had its info confused (with me following), but was later corrected: http://forum.thinkpads.com/viewtopic.ph ... 40#p627240
In the meantime I have done over 100 SATA-mods, but have discontinued doing them in July 2015.

[berrieds]

Well, thanks for clarifying that anyway.

I'll post some pictures when it's all done, some time Mid-January.

Thanks for all the advice, RBS. It wouldn't have been possible without your help

Hi All,

Writing to report yet another successful T43 SATA mod. The main difference in my case was the way I removed the bridge. Even though because of almost no soldering experience whatsoever I was uncomfortable with the heat gun method since the very beginning I still tried it a few times first, using SolderPro 120 gas iron with a cone shaped nose (RBS's know-how). Unfortunately the bridge didn't move even when I kept heat on for a couple of minutes, perhaps due to insufficient heat generated by this tool (strange though), so I gave up to avoid the risk of burning something around the bridge. I then tried my "multi rotary tool" (aka Dremel tool) with various bits:
http://www.ebay.co.uk/itm/ROTARY-MULTI- ... 1022281350

Starting with a ball shaped sanding bit, I destroyed the middle of the bridge down to the heat sink on the mobo, and then used other suitable sanding and cutting bits to split the remainder of the bridge into several pieces that could be safely removed one by one. The tool has to be applied extremely carefully, for a fraction of a second at a time followed by visual inspection of the effect. The sound of sanding or cutting bit touching the bridge also helps control the tool. It wasn't a quick job at all (probably something like a couple of hours) but definitely gave me more control over the process. If done carefully enough, this method leaves the mobo underneath the bridge absolutely intact.

When soldering SATA signalling cicruit wires it helps a lot to stick them into their respective holes in the mobo near the bridge seat first, so I used really thin single core wires cut off from IDE ribbon cable: their diameter is a perfect match for those holes. For SATA power circuits I took much thicker multi core wires.

Update: some pictures, as promised:

Objection, Your Honor!
Never even heard of SolderPro till today!
All my SATA-chip removals were done with this El Cheapo heatgun: http://forum.thinkpads.com/viewtopic.ph ... 64#p725664
Time required: less than 2 minutes!

[dandreye]

Hi RBS - Merry Christmas! (same to everyone actually)

Over the last couple of years I scrutinized everything you've ever posted on this subject and yes your method is probably the best... for anyone who is at least familiar with this hot air station soldering unlike me. I've seen someone's post here reporting how he inadvertently pushed a nearby resistor away from its seat while using heat gun and then had a lot of pain forcing it back into its seat. Perhaps had he insulated the surroundings from heat using foil like you (used to) do he wouldn't have run into that issue. I also tried putting foil around the bridge but it's such a precise action that I found it extremely difficult to permanently seat the square opening exactly where it needs to sit: it'd always move a millimeter one side or another, exposing one or another resistor to heat. I found mechanical method way less damaging for my poor nerves ))

> Never even heard of SolderPro till today! All my SATA-chip removals were done with this El Cheapo heatgun: viewtopic.php?p=725664#p725664

Apologies for what looks like my poor wording: I implied borrowing only the cone shaped nose idea from your heat gun and using it with my gas soldering iron. Btw I find both SolderPro 120 and that rotary multi tool quite handy for various household applications: highly recommended.


OK, here's a benchmark - I was hoping to see higher write figures but it's an almost 4-year old 1st gen Intel X25-M SSD, hence no TRIM support:



Still at an almost zero cost of the mod (SATA connector has been my only expense so far) I can't be any happer )

[RealBlackStuff]

A less messy (but very delicate) alternative would have been to individually cut all 64 legs with an extremely fine pair of wire-cutters and leave the "legless" chip in place.

[dandreye]

I tried that too albeit in a bad way - using utility knife and without due care, which I much regretted afterwards as it resulted in several bridge contacts on the mobo getting torn off. Fortunately that didn't damage anything critical somehow. I also had an idea of passing a thin wire underneath all the legs at each side of it at a time to detach them (with the help of a fine tipped soldering iron) but couldn't find such thin wire: even the thinnest needle won't get in there.

[ajkula66]

OK, here's a benchmark - I was hoping to see higher write figures but it's an almost 4-year old 1st gen Intel X25-M SSD, hence no TRIM support:

TRIM has really nothing to do with that particular issue.

X-25M is known for weak sequential writes, and there's nothing you can do about that fact. My X-25E - which also has no TRIM, obviously - gets almost double the write speeds that you're seeing.

[dandreye]

ajkula66:

SSD design issue then... In fact even that fairly low sequential write speed is probably still good enough for this T43 platform: it's still well above 50MB/s seen with an HDD in it before. Meanwhile 4k QD=1 and QD=32 write figures are somewhat higher compared to those obtained earlier with it still in my X60s following a Secure Erase (perhaps because of different CDM versions though). Anyway my T43 is now clearly much faster than it's ever been before.

[bretahrnek]

Hello,

After few years I'm back in there.

Just go through garage and found there some of my beauties T43p included.


I hardly remember what happened to it as it's over 5 years since I've used it last time.


I remember that I did sata mod to it and I was successful while had it stripped on the bench.
Then I think when put it together it didn't work. Or maybe it stopped working while glued sata connector ( not sure as it's a while).


What I can say for sure is that now when power on it does 1-3-3-1 beep. Of course I've tried with any possible ram combination and still does the same.
I would like to bring it back to work as it's really nice machine and I just look as brand new ( it's 15" flexview ).

I also have one more that is not in that well state and it's completely dead ( LCD is fine ).

As I can see i have removed the chip and idea connector.
But I have no idea how I did it because I never had hot air gun ( well my soldering skills must had beeen much better while ago )


As I mentioned before I have not been into "business for a while and forgot a lot. Where is a best place to start?
I think if I just solder everything out and see what happens that's a good start. I think the problem is some shortage.


Thank you a lot for any advice. Any help is appreciated

[RealBlackStuff]

Try to rub the RAM gold contacts with an eraser till they shine, then remove any eraser remnants and try again.
Also reseat your CPU once or twice.
When it's all put back (without the palmrest) and still no go, keep pressing on the Southbridge (Intel chip under the wifi-card) and try again.

[RealBlackStuff]

Better late than never...
If anybody wants to still do the SATA-mod on a T43 Intel mobo, here's a picture of where to solder the wires to the (former) SATA-chip: https://i.imgur.com/wmb962H.jpg
AFAIK the HD-LED on Intel mobos was never solved.

[lophiomys]

@RealBlackStuff,

Thank you. I'll keep it in my archive.
One of your SATA-modded T43p's is still in daily use on the other side of the big pond.

Greetings,
Lo PHi

Hi all

I am facing two problems with my T43p (TYPE: 2668-G2J) and T41 (TYPE: 2373-7FA) which, I am hoping that someone here can help. Both laptop's problems are similar.

(1) Due to the rarity of new IDE HDD, I have resorted to using mSATA + an adapter, which I have been successful in DELL and ACER IDE-based laptops. The mSATA that I used is from a Chinese manufacturer, Kingspec (https://kingspec.aliexpress.com/store/5 ... 21450mgMJI) while the adapter is from this supplier: https://www.aliexpress.com/item/3305544 ... 4c4dzcHfvo

Unfortunately, both laptops cannot detect the SSD. What can I do about this? The SSD has been tested on other laptops and is fine. The issue is not with the SSD

(2) I tried to install Windows 10, but it stopped half-way with an error message: "IRQL NOT LESS THAN OR EQUAL TO". What can I do to get around this as I cannot even enter into Memory Diagnostics?

i took both laptops to a repair shop. Regarding Problem (1), , the laptop technician said that both units are too old, and the issue lies with the BIOS being unable to detect newer SSDs. He said there is no way around it as no newer BIOS are available for download, both sets are no longer supported

Thanks in advance to all for your kind assistance

The problem is likely the adapter itself.

As for the other stuff, find another "technician" because the current one is obviously not too familiar with ThinkPads. Quite a few folks around here have been running various SSDs in their T4x/R5x systems.

BTW, you can't install W10 on a T41 since the CPU doesn't support it. It will work on a T43 though.

Good luck.

[lawgilbert95]

Thanks for your quick reply
The adapter has been tested on other sets (DELL, and ACER), and it works
as for Win 10, I tried to install a 32-bit version in the T43p, and the error message "IRQL NOT LESS OR EQUAL TO" appeared, multiple times

[ajkula66]

Thanks for your quick reply

Well, ThinkPads often have a mind of their own. I used an Addonics adapter in a T42p several years ago with no issues.

as for Win 10, I tried to install a 32-bit version in the T43p, and the error message "IRQL NOT LESS OR EQUAL TO" appeared, multiple times

I don't use W10 so you'll have to wait for someone else to chime in, but other members have installed it on T43/p so it can be done.

[axur-delmeria]

The cause of the issue is how the HDD port is implemented in the T43, T43p, R52, and X41.

The Intel ICH6-M southbridge only has 1 IDE port, and at least 2 SATA ports. IBM chose to route the IDE port to the Ultrabay, and used an IDE/SATA bridge chip for the HDD port.

Now the problem is that the IDE to mSATA adapter also has an IDE/SATA bridge chip, and having two such chips in series causes lots of issues, as you're experiencing now.

[Shredder11]

In my T43p I have a Plextor 128GB-PX-128M6M mSATA SSD drive plugged in via a Lycom ST-173-7 adapter, and this works perfectly but was expensive back in 2015 at £100 total. I also have some Kingspec 128GB SSD mSATA I think that work fine in all my IDE based Thinkpads, although I use a different adapter with those. That was a cheap combination from aliexpress a few months ago, and cost only £20 or something in total and performs very well.
