Lenovo Slim 7 Aura Edition

✅ Method 1 — Flip it over (works even if it won't turn on)

• Power off, close the lid, and turn the laptop upside down on a towel or soft surface.
• Find the printed label near the regulatory markings. Look for the line marked Model or Type.
• You want the code ending in 15ILL9, 14ILL10, or 14IPH11.
• You'll also see a Machine Type Model (MTM) number — a four-character code such as 83HM, 83JX, or 83NM, followed by more characters. Send us the whole thing if you can.
• If the print is too small, photograph it with your phone and zoom in.

✅ Method 2 — Check it in Windows

• Press Windows key + R, type msinfo32, and press Enter.
• System Model shows your full code. System SKU often shows the MTM.
• The same window lists Processor and Installed Physical Memory — write both down.
• For storage, open File Explorer, right-click the C: drive, and choose Properties.
• You can also check Settings → System → About, or restart and press F1 to read the Machine Type Model in the BIOS.

✅ Decoding the machine type

• 15ILL9 — 15.3-inch, Gen 9, Intel Lunar Lake (Core Ultra 7 256V or 258V), 2024
• 14ILL10 — 14-inch, Gen 10, Intel Lunar Lake (Core Ultra 5 or 7), 2025
• 14IPH11 — 14-inch, Gen 11, Intel Panther Lake (Core Ultra 5 322/325 or Ultra 7 355), 2026
• Reading the letters: the number is the screen size, I means Intel, and the final digit is the generation.
• Marketing names Lenovo Slim 7i Aura Edition and Yoga Slim 7i Aura Edition both map to these codes.

❌ This is not a Slim 7 Aura Edition if you see any of these

• Core Ultra 7 155H or any "H" processor → Yoga Slim 7 14IMH9 or similar. Aura Edition began with Lunar Lake, so an H-series chip rules it out.
• An AMD Ryzen processor → Yoga Slim 7a. Every Aura Edition here is Intel.
• A Snapdragon processor → Yoga Slim 7x, an Arm-based machine.
• Weight under 1 kg (2.2 lb) with a 75Wh battery → Yoga Slim 7i Ultra Aura Edition, a separate premium line.
• A screen that folds back 360 degrees into tablet mode → Yoga 7i or Yoga 9i, not a Slim.

Gen 9 — 15ILL9 (15.3", 2024)

• Intel Core Ultra 7 256V or 258V (Series 2, "Lunar Lake") — 8 cores (4 performance + 4 low-power efficient), 8 threads, 2.2 GHz base, up to 4.8 GHz, 12MB cache
• Intel Arc Graphics 140V, up to 64 TOPS · Intel AI Boost NPU up to 47 TOPS · up to 115 TOPS overall
• The two chips are functionally identical — Lenovo paired the 256V with 16GB of memory and the 258V with 32GB, so the processor name effectively tells you the RAM
• Memory: 16GB or 32GB LPDDR5X-8533 · Storage: 512GB or 1TB (1TB maximum)
• Camera: FHD 1080p + IR with a time-of-flight sensor

Gen 10 — 14ILL10 (14", 2025)

• Intel Core Ultra 5 226V / 228V or Core Ultra 7 256V / 258V (Series 2, "Lunar Lake") — 8 cores, 8 threads
• Ultra 5: Arc Graphics 130V up to 53 TOPS, NPU up to 40 TOPS, 8MB cache, up to 97 TOPS overall
• Ultra 7: Arc Graphics 140V up to 64 TOPS, NPU up to 47 TOPS, 12MB cache, up to 115 TOPS overall
• Memory: 16GB or 32GB LPDDR5X-8533 · Storage: 512GB or 1TB
• Camera upgraded to 5.0MP + IR · adds a microSD card reader and Ultrasonic Human Presence Detection

Gen 11 — 14IPH11 (14", 2026)

• Intel Core Ultra 5 322, Core Ultra 5 325, or Core Ultra 7 355 (Series 3, "Panther Lake")
• Ultra 5 322: 6 cores (2 performance + 4 low-power efficient), up to 46 TOPS overall
• Ultra 5 325: 8 cores, up to 47 TOPS · Ultra 7 355: 8 cores, 2.3 GHz base, up to 4.7 GHz, up to 49 TOPS
• Memory: 16GB or 32GB LPDDR5X-7467 — note this runs slower than the 8533 memory in Gen 9 and Gen 10
• Storage: 512GB, 1TB, or 2TB — the first Slim 7 Aura Edition to offer 2TB
• Supports up to four independent displays; drops USB-A and HDMI (see the ports section)

Memory — soldered on every generation

• 16GB or 32GB, soldered to the systemboard with no slots. On the Lunar Lake generations the memory sits on the processor package itself, so it physically cannot be changed.
• There is no upgrade path, no aftermarket option, and no service-center fix. Whatever your laptop shipped with is what it has today.
• That makes memory capacity one of the two strongest drivers of your offer. A 32GB unit is worth meaningfully more than an otherwise identical 16GB one.
• Confirm yours in msinfo32 under Installed Physical Memory before quoting.

Storage — one short M.2 2242 slot

• Every generation uses one M.2 2242 PCIe 4.0 x4 slot, and it ships occupied.
• 2242 is the short form factor, not the common 2280 length. If you ever tried to upgrade with a standard desktop-length drive, it wouldn't have fit — this catches people out.
• Maximum supported capacity: 1TB on Gen 9 and Gen 10, 2TB on Gen 11.
• If you swapped the drive yourself, quote the capacity installed now.

Shared across all generations

• Copilot+ PC certification with a dedicated Copilot key on the keyboard
• Four stereo speakers (two 2W woofers, two 2W tweeters) tuned with Dolby Atmos and a smart amplifier
• Quad-microphone array · aluminium top and bottom covers, anodized and sandblasted
• Firmware TPM 2.0, camera e-shutter switch, IR camera for Windows Hello face sign-in
• No fingerprint reader on any configuration — face recognition is the only biometric option
• MIL-STD-810H tested (21 test items) · Intel Evo platform · Eyesafe Certified 2.0

Gen 9 (15ILL9) — 15.3-inch

15.3-inch 2.8K WQXGA+ (2880 × 1800) at 500 nits, 120Hz, 16:10, 100% DCI-P3, glossy with anti-fingerprint coating. Two panel types were offered: an IPS version with in-cell touch (1,500:1 contrast, DisplayHDR 400, TCON color calibration) and an OLED version without touch (100,000:1 contrast, DisplayHDR True Black 600, X-Rite factory calibration). Screen-to-body ratio is 91.5%.

Gen 10 & Gen 11 — 14-inch, all OLED

Both 14-inch generations are OLED on every configuration, in four variants: 14" WUXGA (1920 × 1200) at 60Hz with 600 nits HDR peak and DisplayHDR True Black 500, or 14" 2.8K WQXGA+ (2880 × 1800) at 120Hz with 1,100 nits HDR peak, PureSight Pro branding, and DisplayHDR True Black 1000. Each comes in touch and non-touch. Gen 11 adds 99% Adobe RGB coverage to the 2.8K panels. All are X-Rite factory calibrated with ∆E under 1.

OLED burn-in — please check this

Because the 14-inch generations are OLED across the board (and the 15-inch had an OLED option), burn-in is a real consideration. Static elements like the Windows taskbar, a browser tab bar, or a Teams sidebar can leave permanent faint ghosting after heavy use. Display a solid white or light gray image full-screen at high brightness and look for retained outlines. Burn-in reduces the offer but does not disqualify the machine — reporting it up front means the quoted number is what you get paid.

Which panel do I have?

Open Settings → System → Display → Advanced display. A reading of 2880 × 1800 at 120Hz means you have the higher-tier panel, which is worth more. 1920 × 1200 at 60Hz is the base panel. To check for touch, just tap the screen — or look under Device Manager for a "HID-compliant touch screen" entry.

Battery & charging

70Wh on all three generations, with Rapid Charge Express — about three hours of runtime from a 15-minute charge, though only from a fully shut-down or hibernating state. Lenovo's rated figures: Gen 9 reaches 13.5 hours of web browsing and 22 hours of video; Gen 10 reaches 17.5 hours on MobileMark 30; and Gen 11 pushes to 21.4 hours on the WUXGA panel. Ships with a 65W USB-C adapter — a 3-pin brick on Gen 9, a slimmer 2-pin wall-mount design on Gen 10 and Gen 11.

Size & weight

Gen 9: 343.8 × 235.4 × 13.9 mm, from 1.53 kg (3.37 lb).
Gen 10: 312 × 219.3 × 13.9 mm, from 1.19 kg (2.62 lb) non-touch or 1.28 kg (2.82 lb) touch.
Gen 11: 312 × 221 × 13.9 mm, from 1.14 kg (2.51 lb) non-touch or 1.22 kg (2.69 lb) touch.
All three are 13.9 mm thick.

Colors

Gen 9 shipped in Luna grey only. Gen 10 and Gen 11 added Seashell as a second option. Color doesn't usually change the offer, but the lighter Seashell finish tends to show grime along the palm rest more visibly, so clean it before photographing your condition.

Keyboard & touchpad

Six-row backlit keyboard with 1.5mm key travel, multimedia function keys, and a dedicated Copilot key. Large buttonless glass Precision touchpad measuring 80 × 135 mm (3.15" × 5.31") on all three generations. No numeric keypad, even on the 15.3-inch model.

Privacy & presence features

All generations include a physical camera e-shutter switch and an IR camera for Windows Hello. Gen 10 and Gen 11 add Ultrasonic Human Presence Detection, which locks the machine when you step away, plus a self-healing BIOS. Worth testing that the e-shutter slides freely before you grade the condition — it's a small mechanical part that can stick.

Sustainability

Plastic-free packaging with 100% FSC-certified paper, 50% recycled aluminum in the bottom cover, 90% post-consumer recycled plastic in the 65W adapter case, and 30% in the battery pack. Gen 9 and Gen 11 are EPEAT Gold registered; all three carry ENERGY STAR 9.0.
