Howdy folks. So My Inspiron 700m recently stopped delivering sound from the speakers when the laptop is open wider than about 30 degrees. The headphone jack delivers sound regardless, bt I'm wondering if anyone can sggest a quick fix o the speaker problem (which appears to be a wiring issue).

ALSO, I've noticed since the first problem developed, that my larger battery will die suddenly with no warning, leaving the computer at a complete flatline (previously I would receive the "low battery" warning and the computer would subsequently go into hibernation). The battery power lasts only about an hour now, as opposed to it's normal 4+ hour life.

Could these two issues be connected? Do I just need some pliers for the first problem and a new battery for the second? Please advise.

Thank you so much.

Since your speakers are housed in the screen fascia your diagnosis is probably spot-on.

Here is the specs page for what you'll have to do to get at the dodgy wires:

All Lithium Ion batteries contain their own charger and charge diagnostics. If and when the battery tends to flatline without warning it is a definite indicator that one or more of the cells within the battery have gone south.

New battery is called for.

i have seen a similar problem with inspiron 1520, the extended battery seems to be the problem causing unreasoned power offs,for an example when i lift the laptop up off of a table it can just shut down, and the battery has never felt securely attached to the laptop since day one, and i will also randomly get the sound just stop working, but it will work through headphones, would love some help also

You are immediately placing 'pitch and yaw' forces on the hard drive which is spinning at anything between 4,200 & 10,000 rpm, depending on the age and model of your laptop.

That's not wise and certainly not clever.

If your laptop internal sound shuts off without warning, but headphones are alright, I suggest your speaker cabling is questionable. Depending on your make/model of laptop a quick internal examination of the cabling from mobo to speakers may be easy or rather more complicated.

I just experienced the identical problem. My son reseached and found your query. I believe the flatline problem stems from a problem with my charger. I was able to wiggle my charger wire (after flatline) to get lights, but not a complete reboot. I switched to a new charger (from my month old Dell Inspiron) and got an immediate reboot, with no problems since.

I have the same speaker problems. I will attempt the suggested repairs from other replies.
