Dell Inspiron 3567

Replace the DC jack and if the system is running a spinning hard drive, dispatch that in favor of a SATA SSD and it'll run much more acceptably.

@xboyad This laptop was sold during a time when mechanical hard drives were still common in new systems. Assuming that your laptop was shipped with an OEM Toshiba hard drive, they are not exactly the fastest things out there, even when they were new. My Inspiron 3583 came with a Toshiba 1 TB hard drive, and it took 2 minutes for a fairly clean install of Windows 10 to boot to the desktop, where older systems that I had took just under 1 minute and 30 seconds. After I switched out the hard drive with a solid state drive (SSD), boot times drastically decreased to around 17 seconds. Modern versions of Windows are going to be slow with hard drives, as more services and background apps are required to load and run in the background.

That said, I would recommend replacing your hard drive with a SSD, but that's something that should have been done a long time ago. With the recent increase in chip prices, and the fact that Windows 10 has reached the end of support and the 3567 doesn't officially support Windows 11, you would be better off buying a new system rather than upgrading an aging system.

As for the charging port, that could be a bad or incompatible power adapter, or possible damage to the port itself.

@Kflash08​ Alright so, I forgot to state this, But I have upgraded a lot laptops since then, But I still have that one lying around, I just remembered what that laptop had me go through, Since I thought only my Unit was faulty, I took it to a lot of repair shops, But yes, I had this idea of replacing the HDD with a SSD, But maybe soon, Since that laptop is old now, But the thing is, That laptop even when it was new, Was VERY slow, Dell should have atleast tried to do something about it, I know how laptops with an HDD are, They are slow yes, But this laptop couldn't even run Word or Excel when it was brand NEW.

@xboyad​ My neighbor has the same model and has been using it since she bought it new. Out of the box, it worked fine with the stock hard drive. I know, because I helped set it up for her. I later offered to upgrade her to a SSD about four years later, which did make it much snappier.

Can you list how much RAM is installed, and what processor your computer has? If you're still on the original HDD, a SSD will make a big difference. Again, the OEM Toshiba drives that came pre-installed with these systems were not designed for performance. Open Task Manager and monitor activity under performance. If the CPU is barely doing anything but the HDD is constantly close to or at full load when idle, that's usually an indication that something is up with the drive.

You may also want to check your power settings with the My Dell app, and make sure that under power > settings > thermal that optimized is selected, as cool or quiet can have a negative impact on performance, and make sure that the balanced power plan is selected and active in Windows as well. Also, make sure that TurboBoost is enabled in the BIOS. 

Also note that if your power adapter or charging port isn't working correctly, the computer my not be able to properly detect the correct wattage. If it can't be detected or you're using the wrong power adapter, the computer will operate at reduced performance, and will not recharge the battery.

@Kflash08​ Out of the box it had 4GB ram, I remember at that time I downloaded some software on it with the help of my 2012 dell Inspiron, And even that laptop works faster then this one, It also has 8GB ram and a HDD, The thing is that when you buy a laptop, You don't expect to spend money on it right away after buying it, But my Unit was like very slow it crashes on Word and Excel, And about the charging port, Yes thats an Issue, But I'm not getting it repaired just yet, Since I want to see, If this laptop with some upgrades will work today? I was thinking of getting an SSD installed and upgrading it to 12 GB ram, It still has an i3 7th gen so I'll see what I can do, Do give me feedback about this one.

@xboyad 4 GB of RAM is too low nowadays, but should be enough after a clean install of Windows and before installing your programs. My neighbor also has a i3 7th generation processor in her 3567, though with 8 GB of RAM, and it seems to run fine.

As stated before, you'd be better off buying a new laptop rather than spending money on upgrading an old system, especially with the recent increase in RAM & SSD prices. If you decide to go this route, make sure that the parts can all be returned within in a timely manner if none of them improves system performance.
