Earlier today I checked back to see for replies but having seen none, I decided to bite the bullet. I took my motherboard to an electronics repair shop and asked them to solder the jumper for me. I brought thin cables that I took from a spare USB charger cable, and wires from cat5 ethernet cable. The technician used the the thin cables from the USB cord. I bought this wifi-bt combo card from AliExpress and 802.11ac 867Mbps Wireless-AC For AzureWave Broadcom BCM94352HMB WLAN+Bluetooth BT 4.0 Half Mini PCI-E WIFI CARD AW-CE123H Wi-Fi works natively on Windows 10. Bluetooth needed some searching for driver so I let Windows find it for me, and afterwards, BT worked. Checking back here again to report my progress and am happy that @viasat took the time to give his insight. Thank you nonetheless. I appreciate it. Last upgrade would be to replace the mechanical hdd with SSD, but that's until Black Friday / Cyber Monday arrives. Cheers!

@invait53 @anyone I've disassembled my notebook to get the motherboard and now it is lying in wait until I get a response from you. I bought an atheros half-mini wlan AC bluetooth combo card. I want to enable bluetooth. Q: What type of wire should I use to connect the wlan pins to dock? Are the wires from cat5 ethernet cable too thick for the purpose? Should I use a different wire? Will the wires inside a mouse cable sufficient? What type of wire is the best to use? I'm not an electrician nor an electronics engineer. Sorry if this question seems dumb.

Thanks for the quick reply friend. Yes, you are correct. Dirt could also play a factor. In my case, it's just loose connection. It's my conscious choice to stay on BIOS 41 as much as I can. I looked at the BIOS revisions too, but iterations above BIOS 41 does not address issues with RAM not being recognized, so updating it was really last on my list. I'm glad I didn't update. I'm afraid it would mess my Hackintosh dual boot setup on this little workhorse. (I'm currently on dual-boot setup, windows 10 and Mac OS Sierra 10.12.6) I almost believed I made a bad purchase today in buying Samsung RAM. I really suspected it was because my new Samsung RAM had 12800s when on the reference sheet, HP only mentioned 12800 type of RAMs. That, and it having an extra 's' at the end, plus it not being on the reference sheet. But, prior to today, I'm using non-HP RAMs: my dual channel setup uses 4gb Elpida RAM plus 4gb Buffalo RAM and they worked nicely on dual-channel despite not being on the list. So branding was less of an issue for me -- based on my experience with building my own rig PCs. But earlier, it cast doubts on what I think I know about PCs. I was really stumped. So I'm ultra happy these rams work. Got it for just 57 usd used, but in very great condition, and I believe its a steal so I'm super happy at the moment.

@invait53 Thank you for your feedback. I'll try to do the mod once I got the time. Hope you'll have fun once you visit my country. I have another issue I'm facing with today. I bought a pair of used Samsung ddr3 sodimm ram. The sticker on BOTH RAM stick it reads: 8GB 2Rx8 PC3L-12800S-11-13-F3 M471B1G73DB0-YK0 Meaning it has the same part number, perfect for dual-channel. However, if used together, my elitebook would refuse to boot. Using both RAM on both ram slots. Upon power on, the fan would really blow air like the laptop wants to fly. I've never seen my laptop fan go crazy like that. The screen wont power on, and the lights on the home button and caps lock would blink simultaneously. It stays like that until I do a hard reset/power off. If I just use one RAM and put it on the upper ram slot, the laptop would boot successfully, fan is ok. Same case with the other RAM stick. So both rams work independently. If I put one one RAM on the lower slot and no ram at the upper slot, device won't boot. Both RAM slots work as I was using two 4gb of ram on it for a total of 8gb dual-channel. I'm really stumped. HP 2750p supports two 8gb ddr3 pc3L 12800 ram sticks for a 16gb dual channel max. Yet my device refuses to boot. I'm on bios 41. I'm thinking of upgrading to the latest BIOS but that is the last thing I'd do. I would just want to ask here first if you guys have tried installing the same RAM and succeeded. Never mind. I tried reseating the RAM at the lower slot and applied a little bit more force. It finally boots the computer with just one slot. Then I added the 2nd ram on the upper slot. It boots. It appears the 2nd RAM was not getting enough surface contact with the pins of the second slot, that's why it won't boot. Both rams now detected in dual-channel mode. Problem solved.

Hi invait53. I'm looking to buy the wifi card you mentioned. But before I do, I would like to ask for a confirmation: 1) Were you able to connect to an AC speed network using that wifi card? 2) Did bluetooth 4.0 work? Looking forward to your response.

I would just want to report that i replaced the stock i5 3320 procie with a secondhand one, an i7 3612QM that i found for cheap (PhP 1500, or equivalent to $3 dollars) and i couldn't be any happier. Well, except of course for its weight. Its pretty heavy. But I love the built. Very solid. And heavy too. Oh! One more thing, it's a little weighty. But I'm loving it. Added an extra 4gb ram for a dual channel 8gb ram. Pretty satisfied. I hate the charger tho. It's so bulky. Can you guys recommend a slim/lightweight probably 2017 model charger that's easier to carry than the stock charger that works for our 2570p?

Here she is! Unfortunately I spoke too soon about the wifi card's hackintosh compatibility. The card it came was not supported. I still need to find a compatible wi-fi broadcom card. Btw, does the Elitebook 2570p came with Bluetooth module? I can't open my Elitebook yet because of the warranty. https://imgur.com/a/LQyNM

Thanks again @batyanko Today, I can confirm that the 2570p's that I saw were all socketed. I used HP PartSurfer to view all the components of a specific 2570p device. Using the serial number of the laptop and the country it originally came with, I was provided with a tabular list of all the laptop's components along with their part numbers. These part numbers can be googled and can be used as a reference when ordering part replacement from HP. Anyway, using the HP PartSurfer, I confirm that the laptop has a socketed CPU (system board part number 685404-001) and it also list that the board is fitted with an i5 3320M cpu which also answers my question of wether the 3320m was soldered or not. The 3320M (681952-001 part number) can be ordered and therefore, can be removed and be replaced by a new one so it is not soldered. Another thing, it also has Broadcom Model: BCM943228HM4L which is compatible with El Capitan if ever I decide to make a hackintosh out of it. Neat! I'll purchase an Elitebook tomorrow.

Thanks for replying @batyanko. If I can't find a socketed 2570p here in the Philippines, I think I'd consider the recommendation of choosing to go Dell e6430. Not for anything, but ordering outside the country would inevitably raise the product cost, and I'm cash-strapped at the moment. On your answer to number 2. I swear my eyes were not deceiving me when I ran i-Nex (a Linux counterpart of CPU-Z) on all three 2570ps i was testing. All three laptops had 3320M installed. All of the three showed the cpu socket type as BGA1023. It's important to note that on Intel's product specifications page, the 3320M was listed to support two sockets -- FCBGA1023 and FCPGA988. i5 3320M Specs. I'm starting to think that the laptops are custom-made as the stickers left on the body of the laptops suggested it was intended for office use. Could it be that the company ordered a bga1023 configuration? To those of you here who have a socketed motherboard, does your CPU-Z reflect you have a PGA988 socket procie? Thanks!

Hi guys. I want to ask for your help. I want to buy a second-hand 2570p, but all I see in the surplus shops are those equipped with 3320m processors. Unfortunately, these shops won't allow for me to open the case to see it the cpu inside is removable or not. I booted Manjaro off a USB (as the laptops doesn't have an OS installed) and installed an application i-Nex (similar to CPU-Z). The app i-Nex reported the cpu inside to be of socket BGA1023. 1) From what I learned so far, BGA processors are soldered on the motherboard. Does that mean the 2570ps I saw contained a soldered 3320m processors, making my plans to upgrade to 3612qm impossible? 2) Plus, do HP 2570ps with soldered cpus exist? Those I saw were 2nd-hand 2570ps from Japan. 3) How would I chose a 2570p that has a no soldered CPU if: a) I'm not allowed to open the case (seller has those warranty stickers that will get broken if the case is opened), and No OS installed on the laptop, so no CPU-z? c) Store personnel are totally dumb about laptop internals. Please advise me guys. I need to purchase one and upgrade the dual core to a quadcore.
