In my book, if the AC indicator doesn't light up when the charger is plugged in, it's either a faulty LCD cable (which in the T60 also carries signals the indicators), or the board itself is toast.

Looks more like a system board issue. Regarding the CMOs battery: the battery is used not only to keep the date and time, but also to store settings on the CMOS RAM. If the battery voltage sags (drops temporarily but not yeat dead/flat), it can cause the CMOS RAM data to get corrupted without the sy...

From what I've read, the Intel HD 4000 graphics in Ivy Bridge processors (like the ones in the X230, T430, T530 and W530) is roughly equivalent to the Radeon HD 3650. I don't have benchmarks to back it up though.

Something like this? https://www.amazon.com/Transcend-PCMCIA ... B0009M069Y

Well they're basically identical machines(and use the same FRU Mobo...so it being electrically compatible really isn't a surprise. Never had access to ancient Thinkpad models save for the 760XD so this is new to me. Reminds me of the interchangeable parts of the T4x and R5x series, especially the s...

Nice! You're lucky that the two are physically and electrically compatible.

In this case, yes. Technically, I believe that it is possible for a Bluetooth adapter to be integrated into a MiniPCI card (those wireless+modem combos?), although nobody has done that yet. It's possible on mini-PCIe and M.2 because they have USB signals on the connector (the BT part is almost alwa...

My concern is that I don't know if the X220T's HDD bay can be safely used for hot-swapping.

Just get a VESA compatible MiniITX case and be done with this. There is no point in modding an M72 when a much easier solution exists. Another issue is the video input of the screen. Even if it's eDP (Embedded Displayport) I've yet to encounter a motherboard with Displayport output; it's usually ju...

My X220 is sporting a 60GB Kingston mS200 mSATA SSD, which I bought over 3 years ago. These days mSATA is not a cost-effective option for SSDs, so I'm weighing my replacement/upgrade options.

You can set in via Windows:



Alternatively, you can use RMClock or Throttlestop for greater control.

X61 runs fine overclocked. X61s successfully overclocks but crashes often. I'm using the same RAM chips in both machines. 1. You can try increasing the voltage on the X61s. 2. Limit the clock speed (by setting a lower multiplier) to just slightly above the original speed. You'll still get a perform...

Running CPUID on the X230, it says ram slot 1 is running at 1.5volts, slot 2 is running at 1.35 volts. On the X220, both slots are at 1.5 volts. It all seems a bit weird and confusing. The memory controller inside the Sandy Bridge CPUs doesn't have proper support for DDR3L, so it runs at 1.5v. The ...

You mean you had to flash a BIOS update to fix it?

As far as I can see under magnification there is no identification whatsoever on the CPU.

That's strange. I was expecting something like this: http://mixeurpc.free.fr/SITE_x86-guide/ ... 3%2003.jpg

Remove the heatsink, take a picture of the processor, run the part numbers on Google.

Take note that the Radeon X1400 only supports OpenGL 2.0. You'd probably need a more recent card if you want to play newer games.

but can X300 mobo be replaced with something newer?

You can't even put an X301 board in there without modifying the chassis, as the X301 has a DP port where the X300's rear USB 2.0 is located, and that USB port got relocated next to the LAN port.

Maybe the dock's DVI port has a problem.

Or the DVI cable itself is bad.

I've seen pictures of the X330p showing additional holes at the bottom of the chassis, directly under the fan.

This implies that the stock cooling system is inadequate in dealing with the quad-core's heat.

One way to check is to use the W500 normally while keeping Task Manager open and keeping a close watch on the RAM usage. If you consistently exceed 80% RAM usage, then adding more RAM might be a good idea. On the other hand, since you already have an SSD, the slowdown caused by using the page file/s...

To get an Ivy Bridge CPU into an X220 requires a number of things:

* Replacing the stock BIOS with Coreboot/Libreboot

* Access to a BGA rework station, because the CPU in the X220 is soldered to the system board

* an Ivy Bridge CPU in BGA1023 socket/form factor.

I guess the number of people who:

* have an X61T with bubbles
* have access to a vacuum chamber, and
* are members of this forum

is very small (if not zero).

Just going to say this but .... ReactOS? I haven't tried it yet but you might want to take a look there. ReactOS is nowhere near stable enough, and many drivers don't work. Here's a blog post by someone who tried in on a T430: https://panoramacircle.com/2018/11/28/reactos-running-on-real-hardware-t...

It's not the GPU. The Intel HD 3000 graphics in the X220 is part of the processor itself. What you're looking at is the Platform Controller Hub (PCH) which is the equivalent of the southbridge chip. It handles the USB and SATA ports, as well as the PCIe x1 links for the WiFi card and the Expresscard...

These aren't the issue. Its entirely software related. I have 3 T420's and two have this issue AFAIK. One of them is practically NOS and never touched. I run 7 as a result. @lawgilbert - why do you need W10..like specifically what won't run/required W10? If that's the case, then he should try a Lin...

I'm seeing some possible causes at the moment: 1. LCD cable issue (specifically wires that carry the EDID data signals). It's possible that without the EDID data, the display controller defaults to 1024x768. 2. LCD panel issue (EDID data is not sent to the system board) 3. Bad RAM-- not very likely,...

Crafting a custom board for a Raspberry Pi could work, since there's the RPi 3 Compute Module, which is around the size of a SODIMM. However, the RPi has lots of limitations which make in unsuitable for general computing tasks.

Based on the X1 Carbon Gen 2 FRU listing https://support.lenovo.com/ph/en/parts/pd030262, it's NGFF/M.2.

The big question is whether the PCIe signals are wired to the WWAN slot or not. I do not know the answer to that one.

Uhh, start hunting ebay for W701ds system boards? Or one with a broken screen?
