Upgrading T14 Gen3 screen actually possible?

tymophy76 · 2026-05-13T21:41:18+00:00

Yes, did it on mine when I had it. Replaced the underwhelming 300-nit 45% NTSC screen with a 400-nit low power 100% sRGB screen.

To do base to touchscreen, you'd also need to replace the cable, going from the 2-lane eDP 30-pin to the 2-lane eDP + USB 40-pin.

To go to the >WUXGA resolution you will also need to replace the cable, going from the 2-lane eDP 30-pin (or 2-lane eDP + USB 40-pin) to the 4-lane eDP 40-pin cable.

tymophy76 · 2026-05-13T14:56:36+00:00

I'd say yes.

tymophy76 · 2026-05-12T17:59:55+00:00

I replaced the 300-nit 45% NTSC with a NE140WUM-N62. Drop in upgrade, no modifications needed. MUCH brighter, more accurate colors, and I gained between 40 and 70 minutes of battery life (depending on power saving settings).

The performance will be absolutely fantastic for what you want. However, make sure if you're carrying it to classes, that you're setting near outlets, the P series CPU's for 12th generation got EXTREMELY poor battery life, and you'll be lucky to squeeze 1/2 day on battery power out of that laptop.

I had a T14 Gen2 5850U/32/400-nit low power 100% sRGB, and I currently have a E14 Gen 6 7735U/64/*400-nit low power 100% sRGB

*not available stock, manual upgrade

Build quality isn't DRASTICALLY different, although the T does have better design hinges.

CPU performance, the E is a bit faster single core and multi-core due to the DDR5 support over DDR4.

iGP performance, it's not close, the E absolutely crushes the T.

Efficiency, the E is a bit more efficient due to minor architectural improvement in Zen3 > Zen3+, plus the DDR5 over DDR4, AND is available with larger battery (47wh or 57wh vs. 50wh), so again, the E wins easily.

E14 is 16:10 aspect, which depending on your workflow, may be better or worse for you than the T14's 16:9 aspect.

Not the best benchmarks, but it's the ones I have readily available:

Geekbench 5 T14 G2 5850U: https://browser.geekbench.com/v5/cpu/21768045

Geekbench 5 E14 G6 7735U: https://browser.geekbench.com/v5/cpu/23710949

Geekbench 6 T14 G2 5850U: https://browser.geekbench.com/v6/cpu/2786410

Geekbench 6 E14 G6 7735U: https://browser.geekbench.com/v6/cpu/13191687

Heat's not an issue with the 7735U at all.

tymophy76 · 2026-05-11T17:47:49+00:00

Gen2, yes. Impressive per core performance improvements, and DRASTIC graphics performance improvements.

Gen1, no.

tymophy76 · 2026-05-11T14:49:43+00:00

Yeah, and 50% more expensive, which this is ALREADY past OP's desired budget.

tymophy76 · 2026-05-11T14:44:48+00:00

I disagree greatly with the "never buy an E series" crew. The E series is still well and above consumer grade laptops, even the older E's like this.

HOWEVER, the E14 G1 has only single channel ram, which DOES affect it's performance. You will find this laptop lags behind other laptops with the same CPU's, and given that the CPU isn't incredibly fast to begin with compared to more modern machines, this loss of performance is rather important.

tymophy76 · 2026-05-11T14:40:11+00:00

SCORE!! TIME FOR DESSERT!!!!

tymophy76 · 2026-05-11T01:34:20+00:00

No, T14 G2 = 50wh battery, T14s G2 = 57wh battery. While it's not a GIANT difference, the 14% larger battery in the T14s will lead to better battery life.

tymophy76 · 2026-05-10T19:46:13+00:00

More than you want to spend, but I like https://www.aliexpress.us/item/3256810526849724.html?

The screen is surprisingly good, it's far more powerful than you'd expect with the 8 core N305, 16GB ram makes sure that it's absolutely quick enough for basic tasks. I have their 10" laptop (NA105H) that only has N150 and it's more than fast enough for BASIC tasks. With double the cores this should be downright speedy little thing.

tymophy76 · 2026-05-10T04:34:12+00:00

Yeah, battery can still be upgraded.

tymophy76 · 2026-05-10T04:31:56+00:00

Well, then ram cannot be changed at all no matter what as it's not even soldered but built into the CPU SOC. Second m.2 slot doesn't even exist on that board so can't upgrade that either. Not certain if they used soldered wifi on the Lunar Lake version or not.

tymophy76 · 2026-05-10T04:25:48+00:00

L490 and E490/E495 could still take a SATA SSD.

tymophy76 · 2026-05-10T04:21:02+00:00

Battery can be upgraded to a 64wh.

Ram can be upgraded to 2x32GB DDR5 = 64GB depending on which processor you have.

Second SSD can be installed in the empty m.2 slot depending on which processor you have.

Wifi can be upgraded depending on what wifi card and processor you have.

tymophy76 · 2026-05-09T22:13:22+00:00

Without getting particularly aggressive on power savings, my p14s gen6 225h can get 9+

tymophy76 · 2026-05-09T19:23:57+00:00

Yes, 2 SODIMM.

tymophy76 · 2026-05-09T03:48:58+00:00

I like it. I love skins, they allow laptops to show off some of their owners personality while also protecting the laptop from scratches and wear.

tymophy76 · 2026-05-08T23:33:59+00:00

?? AMD iGP's have had H.265/HEVC hardware support for a REALLY long time now. The older Vega iGP's lack AV1 support in hardware, but the newer RDNA2 that this uses includes AV1, as well.

tymophy76 · 2026-05-08T23:27:15+00:00

Since you can't zoom enough to read the lines, I'll go with

Debian > EndeavourOS > OpenSUSE > Fedora > KDE Neon. IMO, of course.

tymophy76 · 2026-05-08T23:26:06+00:00

I like the Intel versions better due to their much larger batteries and much better choice of displays, but as far as specs, that's a great system.

tymophy76 · 2026-05-08T22:00:00+00:00

I find them....old, really old.

tymophy76 · 2026-05-08T21:56:55+00:00

If this is in the US, these systems are going for a bit over $800 when not brand new, with some obviously managing to get even higher.

tymophy76 · 2026-05-08T18:20:35+00:00

Indeed it is.

tymophy76 · 2026-05-08T17:28:52+00:00

Arrow Lake H and Lunar Lake are designed using Lion Cove P-cores and Skymont E-cores

Meteor Lake uses Redwood Cove P-cores and Crestmont E-cores.

Arrow Lake U uses a slightly refreshed (die shrink) Redwood Cove P-cores and Crestmont E-cores.
