I have a laptop computer which have behaved in a rather peculiar way recently.
Description of error:
At times (not all the time, but returning in seemingly random patterns) I get a short string og characters when pressing some of the keys on the keyboard. The string is the character I expected, plus some semi-random special characters (semi-random means it is not always the same short string for the same key, each key has a few strings).
All the "normal" keys (letters and numbers) have this behavior when the error is present, but not every time a key is pressed (about one out of three times). Keys such as *,.^ are not affected.
I have not seen it reappear without first being connected to the internet, which makes me suspect a virus of sorts.
The error has appeared in both Windows XP and Windows Vista, I haven't yet tried Linux (due to the error disabling my ability to use a command lne environment I decided against trying to find the reason in such an environment).
Is it Hardware?
I cannot rule out that the error is caused by a hardware-fault. I tried to test an external keyboard, but as the error keeps disappearing/reappearing and I have no USB-keyboard at home I haven't been able to test it (as there were no error with the usual keyboard when I tested with USB-keyboard).
History:
1) Error first appears: My sister (her computer) experiences the error, it is pretty consistent.
2) I search for virus etc. Find nothing, install diferent OS, reinstall OS. Error seems to be gone, but after a while it reappears.
3) I suspect a hardware fault and deliver the computer for service. They update the BIOS and cannot find the error (remember it dissapears and reappears) (how hard they looked I don't know). They return it.
4) I check that it works, am happy, returns the computer. As we (my sister, and I) boot it up to get on the internet and update the thing the error reappears.
5) I perform the 15 steps on from this board. The error is one for a long while, but around step 15 it reappears.
6) I post here....
The 15 Steps:
During the 15 steps I found nothing... nothing at all (not counting cookies).
The 3 logs are attached.
My gratitude for the time you spend, Uffe
