I have an old T-42 I am rebuilding for the last time. The two magnesium frame parts are severely oxidized and the back frame (which is cut out for the battery has a cracked element). I understand magnesium parts can be cleaned with a 10% chromic acid solution which might then make this amenable to a...

ThinkPad T-420, T-520, and W-520 Nvidia Driver Installation When loading Windows 10 (most recently 20H2), many of the needed drivers (but not all) are auto-installed. Many can be improved upon by sourcing drivers directly from Lenovo, other from manufactures themselves. The most "problematic" can be...

Thanks to the both of you for your thoughts. I summarized what I have learned under the topic "ThinkPad T-420, T-520, and W-520 Nvidia Driver Installation"

I've replaced the motherboard in my T420. The board that was supplied is a 63Y1705 as a substitute for a 04W2049. When installing Windows 10 20H2, an error appeared for an Nvidia GeForce GT-520m GPU. This surprised me as the usual Nvidia GPU is the NVS-4200m. I am unable to find a driver for this. F...

After more "Googling", I found an answer on Reddit at https://www.reddit.com/r/thinkpad/comments/bcbmhw/help_unable_to_recover_thinkpad_bios_splash_screen/ What is pertinent is... UPDATE: was not the UEFI settings (there was a previous post that this was UEFI realated); Managed to restore the boot l...

I have a T-420, two T-520s, and W-520 with modified BIOSs (versions 1.52, 1.49, and 1.46 respectively - Oleh's) Originally these had stock BIOSs, and have been reverted to the previous stock BIOS for reflashes (versions 1.51, 1.48, and 1.45 respectively). In each of these (the T-420, one T-520, W-52...

To answer my own question. No need to fool with this hack. I eventually found a repackaged AX-200 module that was mounted on a half-height mini-PCIe card from China on aliexpress.com. it was about $25. Just know that aliexpress "standard shipping" can take "forever" (1 month) - most of those delays ...

The Touchpad for the W-500-520 is fixed in place with melted plastic studs holding the "U" shaped metal strips down.

Is replacing the Touchpad simply a matter of grinding down the studs, and then gluing the touchpad and strips back into place?

Thanks in advance.

Problem solved (this is very embarrassing, but a lesson learned...) The reason this was happening was from a ruined palm-rest into which something had been spilled, and caused some kind of short circuit. Even though I have removed every other part (including the keyboard), this was the one remaining...

@ atagunov - Believe it or not, they both have the same problem (this reboot problem is what got me to get a "new" motherboard in the first place). Hence my being fastidious in trying to narrow this down to being a software problem (corrupt Windows 10, SSD, etc., or motherboard itself. The replaceme...

@ atagunov - I did the Ubuntu 20.04 install as you suggested (it looks a whole lot better than it did years ago!) after a Secure Erase of my Samsung SSD. As suggested, I used ' hdparm -I /dev/sda ' and hparm -N /dev/sda ' to look for the HDA area that might be there - nothing present. It was also he...

This concerns my T-420 with the 04W2049 motherboard (Nvidia NVS-4200-M Intel HD-3000 Optimus GPU). I am using a modded BIOS 1.52 (83uj33us) (Oleh), but the same things happen with both stock 1.51 (83uj32us) and 1.52 (3uj33us) BIOS (with Intel AC-7260 WiFi card removed). A number of months ago the sy...

Denouement - I put in the i7 2960-XM with the stock heatsink-fan with Arctic Silver 5, and 32 GB (x4 modules) of G. Skill F3-1866-C11D-16GRSL RAM / DDR3-1866 CL11-11-11-32 1.35v / PC3L-14900 8GB-2. CPU-Z shows the RAM as DRAM Freq 797 MHz, FSB:DRAM 1:6, CL 10-10-10-28, 1.35v. HW-Monitor under minima...

As a last addition to my W-520, I'd like to add the last version of Sierra Wireless's 4G LTE mini-PCIe card, the MC-7455 (subsequent cards are M.2 format). I am using an un-whitelisted BIOS 1.46 (8buj25us)(Oleh) which works well for an Intel AC-7260 WiFi card (which otherwise gets an 1802-type error...

@ theterminator93 & atagunov - I also have two T-601F's that I've used for more "vertical" text editing where wide-screen is really a pain. Lying in wait are two Hydis HV-150-UX-2-100 UXGA/LED screens, but I lack the conversion modules. Last I knew, whoever it was, they were behind in production so ...

Most likely not - BIOSs are quite specific for their own component configuration - the T-420, T-520 and W-520 are quite similar in that they all use Sandy Bridge, but the individual inventory of GPUs are somewhat different. Each BIOS has different stepping numbers that don't keep up with each other.

@ atagunov -

I have no experience with T/W-530 swaps into T/W-520's. Perhaps others can help you. Same goes for T/W-530 modded BIOS.

Others maybe able to point you in the right direction.

Thanks so much!!! I was also a "loaded" T-61 user for years and had a similar experience (although not nearly as detailed as your with stress-tests) using Arctic Silver 5 and fastidious preparation with the Arctic Silver cleaning solutions, prepping the surfaces as suggested with a smidgen of AC-5 w...

If I recall correctly, the i7-2960-XM was the fastest CPU made for the T/W-520 (beyond the i7-2860-QM, correc?t). I remember there were a number of issues regarding the heat generated by the XM version - 55 vs 45 Watts, and that this might be an issue with the T-520 heatsink-fan. Having just replace...

I've been working with my overhauled T-520 which is now a W-520 after a motherboard upgrade after the T-520 one died. I'm currently using as a screen an AUO B-156-HW-01 v.7 (glossy) (device code AUO17ED) which I actually love (better than the matte, at least for me). My spouse recently got an X-1 Ca...

I'm now on a clean install of 2004 after 3 years of periodic overwritten updates on my W-520 (which was a T-520 install and then a motherboard replacement to the W-520 board). One thing I noticed is that you are now almost forced to use GPT partitioning if you partition your drive (I assume you are ...

I looked back through my old correspondence (3 years ago), and found an e-mail address for Oleh who did my previous BIOS as I never heard anything from Serg08. He's still in business, and the BIOS works greats with the Advanced menu unlocked. I'm going to give this a try with 32 GB (4 x 8 SODIMMs) o...

Does anyone have experience in try to put an Intel AX-200 WiFi card into one of these? I've tried doing this in a T-420 and mechanically, with an adapter an M.2 to mini PCIe adapter, the only place it fits is the WWAN slot that is full-height mini PCIe. (Not enough space in the half-height mini-PCIe...

i'm a previous user of modded BIOS for T-420 (1.51 (83UJ32US)) and T-520 (1.48 (8AUJ29US)) which had the white list removed and displayed the Advanced BIOS settings. These have worked wonderfully well. (Full 16 GB RAM, Optimus NVS 4200, glossy AUO screens which are crystal clear) updated WiFi with l...

I'm looking for 2 x FRU 42W2510 PCMCIA/Express Card Bezels for T-61 14.1" Widescreens.

Any available or thoughts where?

Thanks!

I'm at the end of a rebuild cycle for two T-520's with Optimus 04W3254 planars. (This follows rebuilding of some T-61's with new stock 44C3933 planars, where I had to solve this Bluetooth problem first which was successful.) The build is with a clean install of Windows 10 x64 ver. 1809, followed by ...

That was an almost "perfect" for T-61, even when the USB-HMD is first in the Boot order. Randomly (apparently) I can still get the <Esc> key message, but it seems much less persnickety about the timing of the Escapes. It is still not clear to me when it wants them - during the BIOS screen or when th...
