I wonder, would 16:10 (1280x800) screen from 2530p work in 2570p (after cutting the bezel and with 40pin to 30pin adaptor)?

This is how the AC adapter looks like when finished. 180 grams versus 290 and about 3 times more convenient. 40W - runs flawlessly 2530p and non-turbo 2560p/2570p. I've also replaced stock cable with Van Damme Unbalanced Pro Patch with silver plated OFC copper core - much lighter and more flexible. Tested the OL protection, kicks in at about 2.35A and shuts down the DC part for 3 seconds. No explosions for this one Marked as Efficiency level V - based on my testing dissipates less than 1W in 5W load, 0W under no-load condition. Played CS:Source on 2530p while charging 9-cell. Adaptor passed with flying colours, temps were below 45°C. I'll write a short DYI, that is if anyone is interested...

Short answer: NO. Going through regulator path reduces conversion efficiency, by as much as 50% <- that is to be avoided in this case. Rather than that, this solution uses 3.3V straight from the system board and thus bypasses any conversion process.

Thought of that before as well. Problem is the casing, once opened it's quite difficult to put it together once you replace the cells (you have to crack open the glued case). The internal circuit can "get used to" the higher capacity, but you must be VERY careful not to cut out the power, otherwise it's bricked. For 2560p/2570p not worth the extra hassle. 100Wh battery has 3100mAh Panasonic cells, which makes 113Whr one only marginally "better". Better solution is to build external battery pack and connect it through DC line. For lesser HP models with 2200mAh cells, or older IBM/Lenovo laptops with 2700mAh that might show noticeable difference. Fitting mSATA SSD into 2560p/2570p After a bit of brainstorming what to do when 2560p does not support mSATA in its WWAN slot, I've come to at least satisfactory solution - use mSATA to SATA adaptor in primary HDD bay. This might appear easy and not worth even mentioning it, however after measuring the SATA port, looking for 3.3V rail which is required I didn't find any. Primary SATA port offers exclusively 5V, which need to be stepped down by non-efficient module to bring us our required 3.3V, and since we're running laptop here, any difference in power consumption make its price. One of the possibilities here is to power the mSATA through WWAN slot, which however assumes that yours is empty. Difficulty: Low/Medium Price: about $10 incl. shipping Time required: 5-15 minutes Skills required: basics with soldering iron Tools required: soldering iron preferably Cardas Silver Solder, with Pb and 4% silver compound (170°C melting point) 15cm thin silicone-insulated wire the following from ebay: New Mini PCI E PCI Express to SATA SSD HDD USB Adapter DIY | eBay Mini PCIe PCI E mSATA 3 x 5cm SSD to 1 8" Micro SATA Adapter Converter Card PCBA | eBay Micro SATA 1 8" to SATA 2 5" Hard Drive SSD SATA Converter Adapter FRU 42W7888 | eBay Once your microSATA to SATA adaptor arrives, undo two screws on the top and take away the board. The reason why I picked this one is that there's no step-down, it's hardwired exactly according to specification. Now you need to solder the wire between 3.3V on the mPCIe card and first two contacts on the microSATA to SATA board. Screw your mSATA drive to microSATA to mSATA adaptor, and put it all together into your Elitebook. Congrats! Now you're running mSATA drive! PS: The laptop should lose some weight as well. PPS: It's possible to run mSATA drive even with WWAN attached, if you solder the wire on first pin with 3.3V rail. However, it's advisable to watch WWAN power requirements, as there's limit 10W on single slot. While Crucial m4 or Samsung PM841/851 will breeze through, Crucial M500 requires at least 5W (I wouldn't recommend that drive, should you consider purchase). And about consumption? Crucial m4 in it's mSATA version requires only about 100mW in idle - compared that to 840 EVO, which needs 300mW, m4 in regular size 500mW. Mechanical HDD 1200mW and Crucial m500 1500mW. So apart from weight loss, you will definitely notice 0.2-1.4W drop when idle.

It's a warranty issue. HDD in enclosure has only 1-year warranty, while 'naked' 2.5" SATA gets 2-year. Personally, I grabbed 'naked' M9T as it's cheaper here than boxed one. Got it new for $109

Today quite odd thing happened. I was able to achieve x28 at even lower Watt figure than x27. I've temporarily "improved" the cooling with vacuum cleaner and pulled out the hot air more rapidly with 1.2kW engine Managed to get temps below 70°C at turbo and with that x28 appeared and got engaged. Strangely at 35.1W instead of 36.5W with x27. Looks like the CPU has lower efficiency when running hot. Anyway the cooling has to be improved. I'm getting 65°C at x14@13W freshly repasted and with service door opened. Will try that copper shim + 0.18mm copper foil between CPU and heatsink.

Yes, the procedure was the same for i5-2520M, once is iGPU fully engaged, it locks out EIST below x24 apparently. I can increase it all the way to x36,but not decrease it.

Perhaps it wasn't entirely clear. This is definitely not TDP issue. If it was, it'd let me run x8 instead of x24 but no. The problem is I cannot run lower multiplier than x24 with Max Performance. This happened on i7-2640M as well, which is AFAIK 35W. I guess it can be fixed through MSR, alternatively it's just bad driver version. Sure, but who has the extra juice in their batteries to power hungry eGPU Also most laptops don't output 12V Weight - about 1.25kg, but provide more than enough runtime even for older, less efficient laptops, such as R60.

Finally yesterday the i7-2860QM arrived so I naturally played with it for a while. Here are my findings: Highest turbo due to TDP throttling was x27, single threaded the CPU does 3.6GHz turbo. Compared to i7-4770K the efficiency is still OK and even surpassed the newer Haswell on lower multipliers Performace measured in Performancetest 8.0 on Win7 x64. Score measured for every multiplier, then divided by stable Watt figure in Throttlestop. However Passmarks are not reliable indicator of performance across platforms as it penalizes the use of 32bit OS and generally include CPU features, rather than focusing on raw power. Real world difference is between 4-6% on same multiplier. 3dMark06 score went from 4750 to 5053 most likely due to extra 5M of L3 cache. Idle package consumption went up by 0.2W (2.9W to 3.1W) However I've encountered several issues - when GPU runs on Max Performance, it forces x24 multiplier on CPU. This didn't happen with i5-2520m. Can this be possibly rectified? x220 with i7-2640M does the same thing. Still few more mods to go...

My mistake, I meant 7.4x5.0mm (it's fixed now) $12 for replacement adaptor, yes, however replacements are not always suitable because: 1) higher RF emissions - equipment noise and possible health hazard 2) no safety mark, no overvoltage protection - DC and AC part is often not reliably separated - dangerous to use in high-moisture areas 3) low efficiency - anywhere between 50-65%, genuine HP and Acer have verified over 85%, Lenovo 78% 4) no overload protection - brick can explode (happened to me). I was suggesting modding genuine 40W Acer, with OL protection, which in this case is necessary should Turbo accidentally kicks in and consumption goes over 45W (5W should be safe margin). In that case, the adaptor shuts itself down for couple of seconds instead of, you know, exploding For those interested in Efficiency ratings (I, II, III, IV, V) see here: http://www.qianqin.de/2010/04/15/notebook-and-other-small-devices-power-supply-efficiency/ http://www.energystar.gov/ia/partners/prod_development/revisions/downloads/International_Efficiency_Marking_Protocol.pdf Surprisingly Lenovo adapter is marked as "V" yet performs as "III" or "IV" - 1W load rendered about 50% efficiency

Acer one would obviously need resoldering with 7.4x5.0mm plug (see 2nd link) and adding appropriate resistor between pin3 and pin2. Still lighter/cheaper solution than $58 45W HP travel adapter: Original 45W Slim AC Adapter for HP Split 13 M210DX X2 Touchscreen Laptop PC | eBay

Are you sure? i5-2520M definitely runs at x8 and vnwhite's i7-2820QM as well: *HP EliteBook 2560p Owners Lounge* - Page 15 I can confirm i7-2640M and i7-2620M running on x8 as well (lenovo x220)

I see you meant SB CPU for 2560p . Yes, I haven't listed everything, only what matters to me the most. USB 3.0 likely adds 0.3W-0.7W to idle consumption and it's little problematic with legacy USB 1.1 devices. My 2560p is still in warranty until Aug-2015, so I'll go with that. Yes I am aware of that little brick, though it still cannot overcome the convenience/weight/price of 40W Acer adaptor which doesn't need additional cord (can be plugged in directly). With power resistor mod, there's still 34W usable for the laptop itself, might be possible to run quad-cores at stock multiplier without Turbo. http://www.ebay.com/itm/Genuine-Original-AC-Adapter-Charger-for-Acer-Aspire-One-19V-2-15A-ADP-40TH-40W-/261577351006?pt=Laptop_Adapters_Chargers&var=&hash=item3ce7399f5e http://www.ebay.com/itm/DC-tip-7-4X5-0mm-power-plug-with-cable-for-HP-or-dell-laptop-adapter-cord-28cm-/141137879913?pt=US_Surveillance_Cables_Adapters_Connectors&hash=item20dc792369

Thank you very much for your answer! Now as I see it, I'll let 2570p go, it's just not worth the extra investment, and so little gain. The thing is, I found one for $800, but brand new with 3 year warranty, if my calculations are correct, then this 'upgrade' to IVY+HD4000+RAID-0 would cost me $300 + $180 new CPU. I'd invest that for new machine, should there were mSata+ASPM fixes+weight difference. Though seeing how things were not much improved, it's really not worth so much money in my case. But thanks again for letting me know! BTW, do you think 2560p / 2570p could be modded to be fanless (passive cooled)? I've checked some of the thermal improvements in this thread (heatsink copper shim) , and the maintenance lid + aluminium screen casing have great heatsoak and dissipating properties. Should the heat be transferred to the screen casing (dunno how yet), even 15W could be theoretically cooled down passively. So far I've been able to dissipate 6W (lowest multiplier on i7-2520M) with no mods at 65°C, no fan, with maintenance lid closed, laptop sitting on wooden desk. With 10W at x12 (quad) performance is slightly above Core2Quad Extreme - would be pretty awesome to achieve that using passive cooling on a 12.5" laptop! @Everyone - stay tuned for Retrofitting IBM-style domed Trackpoint with 2560p/2570p Ultra-light 40W travel-adapter, $25 shipped on eBay (Acer mod) Power resistor mod for slow 10+ hrs charging - significant improvement of battery shelf life (tested 40 full cycles over 2 years = 2% capacity loss!)

Hi there, I discovered 2570p for quite reasonable price, but before I went on purchasing it, I'd like to ask on few things first: 1. Early BIOS for 2570p had disabled ASPM for all PCI-E devices, has this been fixed in newer versions? 2. Can anyone 100% confirm 2570p supports mSATA, if so at which speed 3gbps/6gbps ? - taught myself to read previous posts 3. Weight - I found specs which stated 1.96kg but QuickSpecs from HP listed 1.67kg. The point here is, how lighter it is compared to 2560p equipped with the same accessories? 4. SD card slot - does SD card protrude when inserted? 5. Does USB 3.0 work under WinXP? I didn't find any drivers for it, so it probably will. 6. Turbo Boost - is it possible to disable it in BIOS? Thanks

Today, the 2560p arrived. It has some minor dents and scratches, but otherwise like new. Battery is also in great condition. Will write short review once the CPU arrives. But I absolutely LOVE the sound card. It even surpassed 2530p! Noise levels are below -90dB and the DAC is excellent (supports full 24bit / 192kHz), the sound is even better than on some external cards. Pretty amazing! I was able to visually separate instruments even in some of my very dull and poorly mastered tracks. Output power is also above average. I'm glad IDT didn't remove Stereo Mix, I can talk all day how that functionality makes broadcasting and podcasting 6 times easier. I don't mind the extra weight, since I'm putting there SSD which is lighter than the currently installed dual-platter Toshiba, overall I'm really happy with my purchase. Let's see what the extra 5MB in L3 cache on i7-2860QM do with HD3000 performance, right now I'm getting 4750 score in 3DMark06 with i5-2520M (1366x768). It should arrive within two weeks together with 100Wh battery.

Those are neat features indeed, though I wouldn't call USB 3.0 an advantage. In fact I'm glad 2560p doesn't have one. It presents numerous compatibility problems with audio intefaces and USB sound cards, especially when using WinXP (yet it happens even with Win7) Performance is not the most important factor in a 12" laptop for me. That's why I chose 2530p over Thinkpad x220 and didn't have any regrets. While 2530p is a bit older, it outperformed x220 in almost every field apart from performance. Better soundcard (true 24bit), better screen (PWM regulation which hurts eyes like hell, Lenovo still hasn't fixed that), 16:10 ratio, better keyboard, equippable with 2 HDDs, lower power consumption, standard 12-hour charge for 9-cell (x220 had 4 hours), better touchpad and trackpoint. So it's not just about performance But now, I'd never grab any laptop with LED LG or Samsung screen, no matter it's price or performance. Both panels are very cool, has unnatural green tint to them and are very fatiguing to look at, IPS or not. AUO is by far the best. Warm colours, about 5200K, slightly red, but I'm OK with that. Excellent contrast, no PWM flicker (VERY important), and acceptable viewing angles.

Yes, Ivy might be more efficient, but that would mean spending an additional $229 for 2570p board and about $279 for quad CPU which is totally not worth it considering only 15% gain in speed and 25% gain in efficiency, nor does it matter for my usage. I got 2860QM for just $170 so it's all the way good investment, and it's still fast enough to "compete" with my i7-4770K Haswell equipped desktop. Average Passmark score for 2860QM is 7200, my desktop has 8500, so still great result. I'm expecting to hit native x25 multiplier with 25-28W consumption, Turbo off all the time. 2570p is nowhere to be found here in Europe, and if so far from regular $400. I found a seller with numerous 2560p who let me choose the best one in excellent condition with AU Optronics screen and battery in good condition (50Wh out of 55) for total price $410. So with 16GB RAM, i7-2860QM and additional genuine 100Wh battery, for less than $700, not bad price. I realize that sometimes our ego needs to have the best out of the best, but here the money involved killed the case. However in the future when the prices drop, then I won't have to buy 2570p, just switch MB and that's it.

Hi there, does 2560p support mSATA drive in its WWAN slot (or any other mPCIe slot on the board)? Thanks! BTW Nando4, I'll be getting i7-2860QM for my recently purchased 2560p, if you're still on lookout for potential testers of this particular CPU (according to the 3-year old thread on NBR) I can get into it

You need to shrink BIG_DATA for them to fit there. Then maybe using software such as HD Clone will solve your issue.

Hi, I'm not Andrew and I joined primarily for receiving updates on topics that were closed or outdated on NBR forum. Hopefully in the next 14-days, my dream desktop-replacement will be built, by me of course :-) Cheers!

Hi there, I'm about to purchase 2560p and would like to fit 2570p motherboard. Found some old threads on NBR that it should be possible, but nobody verified it. So is it possible? Thanks!
