Question about Dell Inspiron E1705 Notebook
You have a ground fault issue in the DC JACK.
There are escentially 4 circuits in the jack and one is not making contact.
1: Negative Charge circuit (outter ring)
2: Negative Run circuit (outter ring)
3 Positive (Inner Ring)
4: Signal (center pin)
I believe the negative charge circuit (outter ring) is not making contact internally. Typically what happens on that model DC Jack is the tension contact metal becomes fatigued, and does not touch the outter ring.
This could come from Heat causing early fatigue of the metal.
Or normal wear, the metal has simply worn out from regular insert/removal.

SOURCE: not charging
Dell PA-10 & PA-12 have internal serial ROM chips that communicate with the PC via the tiny center pin in the powerr plug.
If that pin gets bent or is not making proper contact, the laptop USUALLY complains and runs from AC adapter but refuses to recharge the battery ..

SOURCE: laptop won't turn on
The blinking orange battery light generally indicates that the battery isn't working properly, usually going out and not charging properly. In this case, since the adapter will not power the machine without the battery, and it should, I'm going to say that the adapter is going out and not getting the proper amount of power to the system. Try replacing the adapter. Be sure to replace it with a Dell replacement, the Targus brand universal adapters do not work well with Dell machines, and in most cases won't work at all.

SOURCE: battery not charging!
If the battery is 2 years old, then buy a replacement battery, see if it charges. Portable batteries are good for roughly 300 to 500 recharge/discharge cycles before they begin to fail roughly 18 months. Dell warrants the Battery for 1 year, so there is no warranty on the battery. If a replacement battery doesn't charge, then the motherboard will need to be replaced. If under warranty, Dell will fix it, if not, motherboards are $100-150 on Ebay.

Does the laptop power up just no charge the battery? If the laptop does not power on then you may have a bad power supply in the unit. If it does power up than you most likely have a bad battery connector of blown fuse on the motherboard. The flashing of the BIOS is done with a bootable cd or floppy but this will not keep the new battery from charging. The reason Dell states that you need at least 10% battery to flash a BIOS is because if your AC power goes out while you are doing a BIOS upgrade and you don't have battery power the BIOS will be incomplete and your laptop will not boot again without replacing the motherboard.
