As per Intel, the 2820 and the 2720 CPUs have the same wattage. The 2920 CPU uses 10 W more and (in the W520) comes with a larger (and noisier) fan.
I have the 2820qm + 2000M and it is very quiet.
(I tried the 2920 + 2000M, but it was too loud for me).

thank you
also can anyone say if I will choose RAID option, will I available to use sata ports in NON-Raid mode too? so in JBOD mode? or RAID only? -
-
I mean if there are some worse / better performance in raid version controller? or it's the same controller, just with some different bios revision? -
-
I'am for sure going to buy 1000M - but not decided about CPU yet, 2820qm or 2720qm - first one have more cache - i'am going to use many vmwares on the notebook (want to use it as desktop replacement), so thought that more L3 cache can help, but in the same case I want silent solution - so here the main question, how more silent 2720qm is compared to 2820qm
-
also as I got there is no way to use in one time msata SSD + wwan? is it right?
-
That is correct. The mSata card is installed in the same position as the WWAN card. You can always obtain an external USB unit from your carrier which to me has always been preferable than the internal card anyway.
-
but what are advantages of the external USB unit?

Do any W520 owners with the FHD display wish they'd gone with the HD+? I don't like the idea of downgrading from the 1680x1050 on my current laptop, but I have serious misgivings about buying a laptop with a wide gamut display when I don't need it for photo editing. I know Firefox has colour management, but most Windows software doens't. It seems like I'd be limited to Media Player Classic or WMP with a CPU-intensive colour overlay if I wanted colour managed video playback. No colour management in VLC.
I've been told elsewhere that the oversaturated colours in non-managed apps aren't as bad with a 95% display as they are with 110-120% desktop monitors, but I have a hard time believing it wouldn't bother me. There's also the issue of out of gamut blues going purple with a calibrated display, of course. -

Oops, wrong topic. Where's the delete button?

The FHD screen is indeed amazing. It's incredibly crisp and bright, but I had to increase to 125% or else I couldn't read anything.

Guys
Anybody using a bluetooth mouse reliablty with the lenovo 520? I'm looking for one and failed all my attempts to get apple's magic mouse to work
Thanks -
Twas the deciding factor for me. Initially i wanted something smaller, and lighter... but show me a 14" with a decent screen... -
-
I don't know exactly why, but I find myself using the touchpad more often when before I was exclusively TrackPoint except for extended scrolling.
I've gotten the [Lenovo] UltraNav and TwoFingerScroll settings nearly perfectly set, and the textured surface obliterated the initial starting friction found with smooth touchpad. -
What is the B+N discount that everyone talks about?

Hi,
Is anyone running Sandforce SF-2281-based SSDs in their W520? I'm trying to set up my W520 with a Corsair Force GT. I first tried to clone the original Windows-installation over to the SSD. It booted up once, very slowly, and then errormessages after a reboot (missing files or something). Tried to do a clean Windows 7-install, but dosn't help - get a errormessage e.g. with the kernel-file missing.
In addition to the 120 GB Force GT, I have a 240 GB Force 3 in a another computer. Plan now is to try that instead, but just want to check out if there maybe is a more general problem with using SF-2281-based SSDs in this computer. -
-
Will, alignment can give less performance, but the situation now is that the thing will not boot. I just get a 0x00000ec9-error at the reboot during the Windows installation now.
The SSD was cleaned before I tried to use it in the W520. -
However on every Mobo site or OC site, it is strongly recommended you only install matched sets that have been tested together and sold as a set.
I presume the difference is a low clock speed on a laptop chip (mine is an I7 quad core) or on the I7-2600K overclocked to 5.0 Ghz. I presume the extra speed makes the RAM timing and compatibility that much more important. -
anyone tried to replace stock cpu/gpu compound to some Artic Silver to get lower temperatures?
I read that HP owners with 8560 notebook, got good results after doing it - 5-6 degrees lower.
how good this idea is for Lenovo W520? -
Just stop by to report my success in replacing the i7-2820QM CPU in my W520 with a 3.7 GHz i7-2960XM CPU. I have posted a lot of pictures here Intel Sandy Bridge Core i7-2960XM. The captions are in Thai but a picture is worth thousands of words. Please enjoy.

what about warranty in this case? i can forget about it?
-
-
I did this (changed a CPU) before with my T500 and W510. I talked to the local service center in Bangkok, located at the IBM headquarter in downtown. They confirmed that if there is no evidence of accident or that an unqualified personnel has tampered with the machine, then all parts in the "original" configuration of the machine are under warranty. If you change the CPU (by an qualified personnel who knows what he is doing), then only that changed CPU will not be under warranty (which makes sense). -

I'm thinking about buying the below 520. Its a bit pricier than I wanted but has some things I want like the great display and lots of options.
The big thing I added was the FHD and the SSD because for me it was ~$215 option which is reasonable considering what it would cost me to purchase and install. I'm planning on upgrading the RAM not long after I get it to something like 8 GB.
This laptop will be used for classes, video, and maybe some gaming (not Crysis though)
Any other suggestions?

don't want to be negative about w520, as it's still my #1 product I'am going to buy, but seems it's very big lottery today - to get this machine without any issues. and you'll be happy customer, if you will not have:
1. stucked cpu at 800 or 1200mhz (nothing actually can help, if you are super lucky then bios update + some hacky program from 3d party person may help u)
2. custom shutdowns while idle without bsod (mb replacement may help), you can get it serveral times per day or per week. very nice when u have lot of programs opened and it just getting turn off. at least 10% of machines has this issue.
3. thermal shutdowns (mb replacement may help, but again only if u are lucky)
4. optimus bsods (nvidia driver may help or mb replacement, or you have to disable optimus)
and I'am talking not about once time issues, but about very long threads with no s0lutions till now on lenovo.com forums, and lenovo staff doesn't reply there for months, peoples still buying new machines produced in august and september and they have the same issues, and it's 6 months later since production started. is it really normal situation for Lenovo biz range?
the only competitor - I'am interested too, it's hp 8560w - yes it's bulky, less battery, more weight, same or better build quality - but I don't see any so issues with this machine - seems it's just works. or maybe I'am looking into wrong forums? anyway, just read that HP will discontinue PC production, not really happy to buy product what will has no support/future or it's under big question.
right now I'am trying to get the deal with local shop for test drive of their w520 they have in stock for the few weeks, I just don't want to wait for weeks and months while lenovo change there something, if anything will go wrong. I see peoples who sending their w520 3-4 times to lenovo, without any success. what a time/money waste. -
