Laptop charging problem, what is likely tonne the issue?

I have a Lenovo G50 laptop. The hinge is slightly loose which has made the charging port slightly loose but it works fine.

For the past day, I have been having a problem. My laptop charges perfectly fine when off but does not charge when it is on.

It appears to change for a few seconds but then says "plugged in, not charging".

What can I do to resolve this issue?

Is it likely to be the port or the battery.

The battery was working well a few days ago but suddenly started working faulty.

Poor download speed with my laptop?

I have a new laptop, bought mid last year (Lenovo Ideapad with i3 processor) with the bare minimum installed. My router is providing 40mbps download speed on my PS4 and mobile phone but laptop is getting under 1mbps which is so annoying when streaming. I've tried updating all the drivers with no positive result, please help!

What do you think about banking consumer credit for buying a new computer?

I'm from Poland i'm disabled, have Asperger and work in KFC restaurant, my iq is high but have problems with social interaction.

I would like to take a loan to buy a new computer, because in my old almost 10-year-old computer, the procoser slowly crashes, it's the Intel Core 2 Quad Q84000 clocked at 2.66 Ghz, so it's not so bad, my computer also has 6 GB Ram, and graphics card NVIDIA GTX 750 which I bought it two years ago.

I would like to take a loan for a new computer to play, my brother makes fun of me that he acts like a teenager:-)

That I also have a laptop, because I have bought it once for a scholarship fund, it is the B50-70 lenovo but its can be used for at most watching movies.

My brother is afraid that if I took a loan, I could fall into debt loops, but such a loan can be spread even for 72 installments / months, it can also be repaid earlier,

What do you think about it?

PC shuts down, cuts power off?

Recently encountered a problem with my laptop. Everytime i try to launch a game, my pc shuts down. For example: i load Skyrim, game loads up, i try to do something and pc cuts power off. Another example: I load up GTA online and on that moment when game should be fully loaded (when you can start controlling you character) pc shuts down. Happened also while i was watch movies or just browsing internet (even when i was working with MS Word. ). Can someone help me with this?
