Tried pushing the reset button on the back?
Anything is possible, of course, with dying components et al., but the Wallstreet in my long experience of it (I used one as my main laptop for several years) was a model somewhat afflicted by GLOD. So yes, the backup battery (it’s not a pram battery, as its functions are greater) can cause anomalies if it has been sitting awhile without power. Once going, however, it should be fine — assuming you have a main battery installed or keep it plugged in. If all power is removed, you can get problems with these machines.
For anyone not in the know, GLOD = “green light of death”.
