I need information on how to go about replacing the mother board on an HP ze1115. My repairman told me it needed a new mother board but I could buy another for less than what he was going to charge. If you could list the steps and vendors where I can buy parts, it would be appreciated. Thanks.

Quick practical plan (short version): don’t order a replacement motherboard first. Start by isolating the power problem—verify the AC adapter voltage with a multimeter, test with a known-good adapter, and try powering the laptop with the battery removed. If the machine dies or behaves only when the plug is moved, the DC jack or its solder joints are the likeliest faults and are much cheaper to repair than a whole logic board. For safe meter technique and basic DC checks see Fluke’s multimeter guide: How to measure DC voltage with a digital multimeter. (fluke.com)

Step-by-step diagnostics (do these before buying parts): 1) confirm adapter output at the barrel plug; 2) try a different compatible charger; 3) remove the battery and power from AC only; 4) look for heat, burn marks, or wobble in the jack; 5) if you can open the case, inspect the jack’s PCB/daughterboard and solder pads for cracks. iFixit’s DC-jack guides show how common designs expose the jack on a small board or solder it to the motherboard—use those model-specific teardowns to decide repair vs. full-board swap. (ifixit.com)

Repair options and cautions: a replaceable jack or daughterboard is usually inexpensive but may require careful disassembly and (for soldered jacks) fine soldering skills. Use an anti-static wrist strap, organized screw-tracking, and the right bits and spudgers; iFixit documents safe tool use and teardown best practices. If you’re not comfortable with soldering or the screen/battery removal steps, a local repair shop or technician is the safer route. (ifixit.com)

If the motherboard really is dead: identify the exact product and board part number (use HP’s PartSurfer or HP Parts Store to check OEM availability), then compare OEM vs. tested used boards on marketplaces like eBay. HP does not always sell every board new and OEM Windows activation/compatibility can be an issue, so factor that into the cost decision—sometimes a donor laptop or a new replacement is the better buy. Before buying a board, read a full motherboard replacement disassembly guide so you know the full task and parts to transfer (heatsink, thermal paste, etc.). ()

Notes tied to this thread: ’s report of a warm/loose jack strongly favors the targeted-jack diagnosis; ’s warning about full-board swaps is correct—logic-board replacements are time-consuming and often more expensive than alternatives.

:cheesy: HaHaHa your better off buying a new laptop. For starters if you 've never done it before your going to break it. It is not easy to get out you will have to totaally strip down the laptop. Secondly if you manage to find someone who sells your specific board it will probably cost you around £500.
Your best hope is to find a second hand one with a damaged screen or somthing and and use it for spares. Try ebay.
Also what is wrong with the laptop. Please explain. The repair man could be wrong. I am an computer engineer and most repair men are wrong.:cheesy:

After some minipulation, I did get the laptop to boot and windows started. When I touched the jack it was very warm and the laptop went black. The jack seems to be loose. Can the jack be replaced?

I 've just replaced one on a samsung V20 bit hard to get hold of though. I found the one i needed on ebay. Tricky to replace though. You will have to take the laptop to pieces and remove the motherboard. Unsolder the power jack which is the trickiest part. Then solder the new jack to the motherboard. You will need a steady hand and be very careful if you decide to do this yourself. Do not over solder it when putting the jack back on or you could cause the motherboard to short. I would recommend using antistatic mat and wrist strap and make sure you keep all the screws safe . Also remeber where they go you don't want to put it all back together and find you have 3 screws left over.:sad: Be very careful with all the internal cables too.
The jack itself i paid about £8.00 for so thats good. If you live in the UK i could do it for you for a charge let me know and i'll give you my details and how much i would charge.;) Hope this helps.
