How to fix Pavilion DV8t wireless button and volume slider issues

As an owner of a HP Pavilion DV8 laptop, I have generally been very pleased with the product.  After a few months, however, I began experiencing a strange issue:  the capacitive buttons for the wireless internet and the bass/treble slider would occasionally actuate themselves, cutting off internet access and sending the volume into a hissy-fit.  This seemed to happen most frequently when moving the laptop, leading me to believe it was a hardware issue.

After extensive troubleshooting, google searching, and HP support chats, there didn't seem to be any improvement, and the issue still seemed to be hardware based.  Just before resigning myself to sending the machine to HP for repair, I found a suggestion buried in a large thread on a message board, which I decided to try out.  After a couple of days, I'm happy to report that it's working beautifully!

As it turns out, theres a wire under the keyboard that needs to be in contact with the ground plate, and by default is not actually fastened to it in any way, but depends on pressure from the components above.  If the laptop is shifted in such a way that the wire loses contact with that plate for a moment, the problem triggers.  Poor design?  Yes.  The good news is that it's easily fixed!  Here's how:

Firstly, follow the instructions in this document to remove the keyboard.  At that point you should be looking at something like this:


The red box indicates the wire mentioned above.  A better view is here:


All that is needed is to secure the foil above to the plate just below it.  I used masking tape, and everything seems to be working perfectly.

A word of warning though: when removing the speaker plate, do not try to pry the silver side plates of the machine away to facilitate the process, as the clasps that hold it in place are very delicate.  I have a  broken piece of plastic bouncing off of my cooling fan now and then, and its a bit disconcerting.  Worth it though, for a working touch panel.

Good luck on your efforts, and comment below if you find this helpful :-)

The altered passage of time... explained?

According to Einstein, an object moving at phenomenal speed would experience a slowing in the passage of time.  For example, a person aboard a spaceship moving at very high speeds would return home to find that much more time would have passed on the ground than he had experienced aboard the ship.

I propose the compliment is also true:  objects moving exceptionally slowly will experience MORE time than those moving at a normal pace.  This would, for example, explain why a human mind BORED TO A STATE OF NEAR TOTAL ENTROPY would experience far more time than normal, to the point that 2:16 on a tuesday afternoon feels like it should be 5:00 ON FRIDAY!!!

Equally awesome but more readable watch

This watch is great as well.  I'm not sure how I feel about the overall form factor, but the dial itself is fantastic.  The idea is that the hands are joined into a single line, with the thick end marking hours and the thin end minutes. Simple, and perfect.  More pics at the source, click the pic.

Awesome unreadable watch

I love this watch.  You can be certain that when you can use it to tell time at a glance and no one else can see diddly, all bystanders will be suitably impressed.  Click the pic below for more details.

All that idle time to say this:

The left earlobes of mankind will be removed to sate the hunger of the giant space weasel.  That is all.
