Lenovo W520 Owner's Thread

[chenxiaolong]

I'm trying to modify a original Intel 6300AGN to work with the W520. Can someone please post the vendor/product and subsystem ID's of their Intel Ultimate N 6300 wireless card? It can be found in the Device Manager on Windows or by running sudo lspci -vnnn | grep -A13 Network.

Thanks in advance.

EDIT: Nevermind. I found it in the Windows driver INF file:

Lenovo:

; Lenovo_6300_AGN_3x3_HMC
%NIC_MPCIEX_6300AGN_3x3_HMC% = Install_MPCIEX_Lenovo_6300_AGN_3x3_HMC_WIN7_64_MOW    ,   PCI\VEN_8086&DEV_4238&SUBSYS_11118086 ; MOW

Generic:

; GEN_6300_AGN_3x3_HMC
%NIC_MPCIEX_6300AGN_3x3_HMC% = Install_MPCIEX_GEN_6300_AGN_3x3_HMC_WIN7_64_MOW    ,   PCI\VEN_8086&DEV_422B&SUBSYS_11018086 ; MOW

So, for anyone who needs it:

Intel Ultimate-N 6300 AGN
 ID        | Generic  | Lenovo
-----------|----------|----------
 Vendor    | 8086     | 8086
 Product   | 422B     | 4238
 Subsystem | 11018086 | 11118086

EDIT 2: DARN IT! The Intel 6300 has a pin on it that disables writing to the EEPROM. My soldering skill are terrible too .

I just posted a message on the Lenovo Forum describing issues with SpeedStep, Turbo and being stuck at a particular frequency, as of the (latest) 1.27 BIOS, which is the version now shipping. I would repeat the message here, but it's very detailed and constantly being updated with additional information as I discover workarounds. So, your best bet is to just read the latest version at the bottom of this link to page 3 of the thread:

W520: Speedstep not working properly (on battery)!... - Page 3 - Lenovo Community

I'm currently using BIOS 1.26, Power Manager 3.59, and have all my power settings to Max Performance. My i7-2720QM is still capped at 800MHz on AC and battery regardless of what I do, according to CPU-Z. However, running HWinfo64 and Resource Monitor shows me that the processor is running around 3GHz, even when idle. What gives?



All I want my laptop to do is run at 2.2GHZ on idle and full 3.3GHz while under load, on AC. Battery can stay at 800MHz for all I care.

Your CPUs have to be at 100% utilization for the frequency to jump up! Try running Prime95 and watch the frequency in CPU-Z.

It will sometimes jump up when I ran PCMark7, and often went to 2.9 to 3.2GHz when I enabled Lenovo Power Boost+ in Power Manager. I'm just concerned why it idles at 800MHz and doesn't jump unless I'm benchmarking. So what you're saying is that I shouldn't be worried at being stuck at 800Mhz (for the majority of the time) on AC power?

Well, there's no point in running full throttle when there's no need for it. I.e. revving your car engine at a red light.

Also TI-89 Titaniums are awesome. Doom89 FTW. XD

No, you shouldn't, unless you have latency sensitive apps where the transition from 800MHz to the P0 state (the highest multiplier) will impact them.

Hi everyone

I posted on lenovo forums but got no response so I'm coming over here to check with you guys.

Does anyone know if my W520/all W520s are compatible with the FHD screen for W520 being sold on eBay, specifically the AUO B156HW01 V4.

My model/machine code is 4284-A99, currently running the most basic HD screen, 1366x768.

If compatible, are there any issues, eg. Having to replace the cables / different mount or frame holding the LCD in the bezel?

I did do a search but haven't found anything conclusive, nor my specific machine code in the FHD LCD screen FRU replacement from the manual.

Also, does anyone have a link to a tested 3rd party ultrabay for 2nd HDD? The original lenovo ultrabay offered locally is kind of pricey at $100+, but I'll get that if there are no other alternatives.

Thanks!

Anyone has any idea?

The original SATA Ultrabay Adapter III is not $100+ vector1, and it can be found here for $60.

Hi Aesdecryption

I'm referring to my local price, quoted by the service centre. I would prefer locally if I'm getting a original ultrabay.

I'm actually more curious whether it's possible to swap my LCD screen out.

If no one knows, how should check? I could open up my screen to check the connectors, but how do I know they are compatible without buying the new FHD screen?

Thanks!
