First, I would like to greet everyone.
Second, let's get into the problem
HP PRobook 450 G1 laptop, was manufactured in 2014, Windows 8.1 64-bit, Kingston SSD in the HDD bay and the HDD that came in the DVDRW bay, this laptop may be old but does not have many hours of work, maybe 2000
After the operating system starts, randomly and not always, the left click acts as if it were stuck, it is selected as if ctrl had been pressed, and as I said it is random, not at every start of the operating system. This problem disappears if I press Left Ctrl, sometimes, Right Ctrl, sometimes again, or Mouth Ctrl, again sometimes, it is random, mainly Left Ctrl works.
the other problem is always present and not as annoying as the first, but I think it is connected to the first
when left shift is maintained + g = tg
when the left shift is maintained + h = yh
when the right shift is maintained + g = rg
when the right shift is maintained + h = uh
If you press Right Ctrl with the letters h and g, it works as expected, double letters are not written
The only letters that manifest this problem are G and H
and now the troubleshooting I did to solve this problem
I connected my desktop keyboard to the laptop and it works as planned while I type on the keyboard with it connected and typing on the laptop keyboard, the problem is still there (it makes you think it's a hardware problem)
I reinstalled Windows, the same problem,
I installed ubuntu, same problem
I installed a virtual machine and used the desktop keyboard, the same problem,
I fiddled with Windows settings and regional settings, the same problem
I took out the keyboard and put it on again, the same, I will soon try another compatible laptop,
any ideas ? Thanks in advance!
