How to repair ubuntu after deliberate motherboard short circuit

Asked by shaf quadri on 2011-06-11

I would like to know what is the best course of action to take. I short circuited my mother board to bypass a bios password (a bug with Toshiba Satellite laptops easily fixed with new bios installation) Since the short or bios upgrade, Ubuntu has been acting weird. It takes a very long time to establish wireless connection my router and then promptly disconnects within a few seconds, I can't control audio volume from the control wheel on the laptop, power state (charging or battery level) no longer shows, and computer doesn't hibernate on closing the laptop lid nor does it completely power down on shutdown command. It freezes at the Ubuntu screen at 3/5 dots but doesn't completely power down without manually depressing the power button. Thus, I was wondering if I should reinstall Ubuntu or repair it. I run a dual boot system and Windows is unaffected, i.e., working normally.

Help much appreciated.

I suggest you test your RAM in the first instance

RAM is fully functional.

What version of Ubuntu are you running? Do the problems occur when you run Ubuntu from a live CD/DVD/USB (instead of running the system that is installed on the hard drive)?

I'm running Ubuntu 10.04 fully updated from my hardrive after partitioning. It was my OS of choice for it's reliability and speed. Also loads up slower than Windows Vista too now. I'm not at all using the ancillary drives, ie, CD, DVD, USB.

Thanks all.

You should test the RAM using memtest in Grub. The short may have damaged the RAM. It will also help isolate a thing as being OK and not causing the issue.

I had taken "RAM is fully functional" to mean that you had tested your RAM as actionparsnip had instructed, but if not, then indeed you should definitely do that now.

If the RAM test out fine, then please answer my question about whether or not the problem happens when running from a live CD/DVD/USB. You will have to actually **try that out** in order to answer that question.

Can you help with this problem?
