HP All in one 21-2024 processor upgrade

[lplenny]

I am a total novice to computer DIY, but I love this computer in every way except it's insanely low processing speed. I regard it as insult by HP to me as a consumer for HP to have even equipped this computer with an almost useless and work-paralyzing CPU. Injury was added to insult by HP engineering it so that an upgrade just of the CPU is impossible. However, because I will literally have to discard the computer if I can't upgrade it, I am willing to invest a reasonable of money of money and effort to save an otherwise great piece of equipment (small footprint, size and quality of monitor, incredible audio for the price, etc) even at the risk of destroying it because of my lack of experience and training. Please tell me if there is a motherboard available that will allow or include an upgraded CPU and that I might have a chance of being able to successfully install.

The installed processor is not upgradeable.

See the following specifications sheet and click on processor upgrade information.

Your statement "Please tell me if there is a motherboard available that will allow or include an upgraded CPU and that I might have a chance of being able to successfully install."

Unfortunately the answer is no, there is not one available for your AIO PC.

  I couldn't agree more with your assessment of the situation and had I not stumbled into the two I have I might even have an attitude about it especially at retail prices. I have a pavilion 20 AIO  model b013W like new that I literally have nothing invested in but the time to clear the o.s. and install windows 10 home edition in and add another 4gigs of ram from an hp 21 2024 AIO with smart touch that I bought off of Craigslist for $25. After what I diagnosed as a dead or frozen motherboard and seeing that a replacement board was going for anywhere from $50 to $250 of which the most I would consider paying  is less than the lesser. And only because it would be simpler but It would probably wind up in a closet or attic. Now in honesty I have prejudged this model because as I said I got it for $25 not working and without the power supply. But seeing how slow the 20 was I don't think I would ever be content with the touch screen without a serious upgrade because I will test it's abilities doing custom graphics for auto paint design, and there is nothing more frustrating than waiting on a system to catch up or lose what you were working on for lack of ability. After assessing the situation and stumbling across several sites, Intel being one of them that give information on how to adapt different hardware ie: grafting in just about any motherboard and processor you want. And seeing all of the kick ass boards that are available for way cheap. I asked a few more questions than most would ever consider asking and have decided to upgrade the hell out of mine. I have ten year old Pentiums collecting dust that with a few late nights of studying a bit and a bit of soldering, have come to the conclusion this is no different than putting an engine out of a corvette into a miata! People do these kind of things daily. Aside from a few of the exterior connections having to be altered I am sure a great deal of laptop and notebook motherboards would work with  little help. I may have to do the equivalent  of putting a hood scoop on the back to allow for the supercharged blower on the ecu to clear as well as the power supply, unless I extend the harness and make the equivalent of the original AIO which isn't all in one when it's power supply is in the floor with no cooling fan. I haven't got it all figured out quite yet as I am sure this thing is probably going to need wheelie bars, a roll cage, and an onboard fire extinguisher! Hmm wonder where I should put the nitrous bottle! But all kidding aside the answer is not NO the answer is there are options beyond our desire of involvement or the amount you wish to spend but with a little bit of ingenuity these are quite up-gradable you just need a bit of imagination and a Tim Taylor attitude. Can you imagine the look on the faces of the other office workers that have the same AIO when you start that puppy up and the light's in the office dim for a second and the whole system seems to be buzzing an octave higher than the all the others.

 I have been researching the situation and I have what looks to be a better than imagined solution! The mother board used in the hp envy all in ones 23-27 inch  smart touch models is almost an exact fit for the 21 2024.  It appears the biggest difference is two of the four usb slots in the back of the board are off set  and will need holes cut for access and maybe some other minor issues.You will need the NVIDIA Ge Force GTX 1050 (4 GB GDDR5 dedicated)  you will also need an Intel Core  processor,  the envy uses the Intel® Core™ i7+ 8700T (2.4 GHz base frequency, up to 4.6 GHz with Intel® Turbo Boost Technology, 12 MB cache, 6 cores) but an i5 would work beautifully and unless you do a bit of shopping the i7's are over $300 alone, this is entire build isn't going to cost that much!  And 16 GB DDR4-2400 SDRAM (2 x 8 GB).

All right now for the down and dirty! The mother boards : HP Envy TS 23SE-D AIO Intel Motherboard s115X 732169-501are available for $15 + $15 shipping and have a 60 day return for exchange, found on ebay last check there were  a dozen or so at the present. The NVIDIA I found for $42 by googling and doing some searching. Their is also the onboard vga if you dont find or want the NVIDIA at the present it can be added anytime. The processor isn't paramount in the final results because they are going to be so spectacular who going to notice 3 or 4 more sky rockets  going off when you just increased the 5 to 25 if you catch my drift. Just saw a 3.7 gh  i5 core processor on ebay for $35 and  ram at best but for $42 and best get a 250 watt power supply on the list I sure wouldn't want any problems from lack of fuel. Figure another $25 . If you can locate the Items I just did in just about 4 hours of actual time to write this research it and find the pieces you should be able to make a serious upgrade for way under $200. Good luck I think I am off to order a board!

One thing I didn't mention is that when installing a larger ecu especially when installing a different board is that in the event it doesn't clear in any particular place you know have a problem . The ecu will also need to be supported. A flat piece of aluminum cut to the dimensions of the motherboard and then marked and drilled with a 1/8'' inch drill bit to match the mounting points of the board is necessary. I believe Intel offers mounting boards. You will have to space the board about 1/2 from the plate to allow for clearance. There should be source for threaded spacers to acquire them or you can cut copper tubing  in equal lengths and with a little crimping and a course thread screws you can accomplish the same effect.
