I own a g50-70 for about 2.5 years. It's my first Lenovo product, a replacement for what has been a very reliable Acer laptop. Since I don't own a PC, I use my laptop intensively.
Since a few months the cable has become increasingly loose in its socket, and as a result the power connection increasingly poorer. This seems like the result of on one hand my own intensive handling, and poor design, since my previous laptop only had this problem due to wear after about 6 years, a significant difference. No, I have not grown into an uncultered savage since then (any worse).
Today I decided to take a closer look which lead to several interesting observations. The power cable has what looks like a copper needle in the plug, and the socket has 6 equally feeble looking copper parts, supposedly the receiving connectors.
I also like to look under the hood of most my electronics, and the first thing I noticed were the missing screws, also a problem I don't expect from a qualitative product, certainly not what I've experienced with previous machines. I removed the casing and to my surprise discovered an empty card slot.
If someone can inform me a little bit about these cards, that would be greatly appreciated.
I'm not into tweaking and upgrading at all, I'm a very docile end-user in that respect, so I wasn't sure what I was looking at. However, the laptop (or notebook if that's the common term) wasn't advertised for upgrade availability at all. The empty slot is an extra one, I don't know if having several card slots is a common standard today in modern products. Certainly an improvement as opposed to the feeble cable socket.
The good thing is that its a powerful machine already. The card is potent enough to run most modern software, programs, apps and games. I would still research the possibilities for hardware improvements, when it comes to cards. It has now become an option. First it's necessary to find a way to fix the socket.
Previously I tried applying pressure with a glue clip, which worked for a while. Now I know it was probably loose because the screws had fallen out at some point. Also inside the machine I found a screw that had completely come loose. Sadly at this moment I can't get it to charge anymore. I think the copper pins and strips in the socket have scrambled from their position to a point where they don't connect to the plug anymore properly. I also don't want to touch them, afraid of bending them further and possibly breaking them. It's also a tiny workspace in there, and I dont have the tools or knowledge to cause anything other than further damage.
It's become unsafe to use now, the plug sometimes heats up to very dangerous temperatures.
I might take the machine to a repairguy since simply replacing the cable won't suffice, which is also necessary since it's inexplicably battered. I also consider possibly finding an alternative device to recharge the battery. I need to acces the machine at least once more to save my files. I was just getting used to it.
Come to think of it, I might buy another one, and put my old hard drive in the new machine. Buys me another 2.5 years. And a spare card.
Thank you reading, leave a reaction if you want, either way have a nice day!

Hi GenericAccount ,
Welcome to the Community Forums.
As laptops are getting compacted to a few space , you would need to have precision tools and skills to work on . Since this would relate on power issue , best to have it checked with your local service centers like best buy as they would have lenovo trained tech to isolate parts needed and check on the integrity of the motherboard.
On similar cases with the systemboard still ok , dc in port / power cables and board may only be the parts needed . Here with is the hardware manual for reference / service video . On near-end part of the manual would be the FRU list to order parts as compared to parts lookup page using your serial number.
Hope this help answer your other query or at least gave you idea how to proceed next.

I'm going to order the replacement DC in cable. The plug was broken.
Another question: is there a way to determine which ddr is compatible with the i3 core? I'm thinking about purchasing a pair of 4GB Corsair ram chips (

Hi GenericAccount ,
Based on the product specification for your model :
RAM : 16GB max / PC3-12800 1600MHz DDR3L, non-parity,dual-channel capable, two 204-pin SO-DIMM sockets
Checking from the FRU list of tested RAM on hardware manual ( item 12 page 80). Directions on how to RAM upgrade on page 41.
As other resellers like crucial would offer possibe upgrade as other options.
Similar discussions here for fellow members on their upgrades on the same model.
Try getting a low voltage DDR3L as this Corsair have 1.5V and may not work .
