Usually, I'd agree with you. In this case the laptop is a bit of a Frankenstein model. The CPU is an engineering sample of an AMD A-10, and the BIOS is missing details of serial numbers, etc. Makes for an odd boot, but it was cheap and does what I want. I've also replaced the stock RAM, drive, wireless, BlueTooth and everything else that could be replaced.
The reboot thing is new and I suspect it has something to do with the boot loader. I expect to be able to fix it.
The Wifi I'll have to investigate. I have some leads, but should be able to fix it.
If it were an off-the-shelf model I'd agree with you, but because of what I've done to it I am a bit more tolerant.
