Who did the work? Mechanic or shop? Then you should call them and ask to check, what code (error code) does system have. Or go to "auto parts store" and ask them to check (some stores like AutoZone or PepBoys can do it for free). And then Google the error code to understand, what it means, and what could it cost you to fix it. Mike | Headset Adapter Co.
First thing - check, what applications are running, and try to close all of them. I found that some applications kill my iPhone 5 in about an hour (even though application is not actively running, screen is off, etc.). Second thing - check if you have "Find my iPhone" enabled. That's what was draining my battery. With this service running, my phone does not survive through the day, while if I disable it, I have more than 50% at the end of the day. Good luck, Mike | Headset Adapter Co.
You may need to cross-check your exact model with an actual hardware you have. Accordint to everymac.com, these models were coming with TWO dual core Xeon CPUs (5150). So, officially you may upgrade your CPUs to dual Xeon 5300 series (they are directly compatible with 5100 series). I think doubling your cores number will be more beneficial. And price-wise, you may find then on eBay for about $50-60. Another "booster upgrade" could be adding more memory (maximum possible) and replacing your HDD to either straight SSD to "hybrid SSD". However you should consider the fact, that this version supports only SATA2 (3.0 Gbps). So, you may need to research, if there are PCIe SATA controllers available to increase your HDD performance.

First of all - the computer is over 25 years old. So, don't expect much from it. :-) From another hand, as a "fun project", to learn new things - it's perfect. At that time technologies were not that advanced, so, a lot of things were "repairable". 1. Don't replace components just because someone else replaced them - evaluate them first. First sign that electrolytic capacitor is (may be) having a problem - the top is not flat. If it shows sign of "burst" with leak, or even little bulging - it's a candidate for replacement. 2. Look for "discoloration" of any components (resistors, transistors, etc). Again, it could be as bad as a "burn mark" on the motherboard, or as little as "little bit brownish spot" on the component. Use a magnifying glass and good light source to examine the board. 3. Not sure, if you can find electric schematics for that old computer (especially with the fact that Apple do not publish their proprietary stuff), but that could be next step up, if visual inspection does not help. ... 99....
You may need to play with a "pressure" on the back cover while you trying to slide it. Usually you put both hands on the back cover, put your thumbs on the front of the laptop (little bit below the edge of the back cover), and try to push it with your thumbs. And here is Lenovo manual, check page 34 and down: https://download.lenovo.com/consumer/mob... Good luck, Mike | Headset Adapter Co. Headset Adapters for Office Phones
I have UX31A. It has soldered memory, so, we stuck with 4Gb RAM. Some other models (UX31xxx with different letters) may have some memory soldered, but some memory available to replace). Good luck, Mike | Headset Adapter Co.
I'm debating myself, which way to take. From one hand, I can find 256G SSDs with original 18-pins for about $100-120 (shipped from China). On another hand, I found an adapter (small one, without long PCB) for $10. But then I have to hunt and bid for M.2 SSDs to get it cheaper than $60-80. Plus, it should be "older" SSD that supports SATA, not just M.2...
