When Ally starts chanting "I need my pack", it can become your worst nightmare. I can't find "the pack" but I'm guessing it's the keypad that you plug into her wrist. My bet is the pin/plug connectors in these dolls were not super awesome quality wise and sometimes didn't register they were connected (the program cards were a bit glitchy as well). Once the batteries need replacing, the doll needs to be reprogrammed hence the keypad connection request. Just a guess...

'Pro 2'. What is that .........

Good day Sheila.
"D:" is often the optical drive (CD or DVD reader / writer).
If so there may be a disk in the drive which is continuously being re-read, especially if the disk has corrupt data.
Eject your CD / DVD and reboot the computer.

Hi Orin.
Topsonic DVD player not seen here (RSA) but have owned several different makes of DVD in the past, so here is my personal method....
Film, download or save a fairly short movie of about 2 min.
Download a free edition of a media-format converter.
MediaCoder and File Converter are both quite good.
Another I used (also good) was (Ulead?) file converter.
Create a folder & sub-folder such as Formats\Video.
Copy the original to Formats\Video.
Use MediaCoder or FC to load, then use save AS or export to export to another video format.
Try various formats and see which plays, (video with sound) note these down, then use Video Inspector to give you a full report of that file.

Sounds like you encrypted the drive. Under Computer, right click the drive and format it. You will lose all your data and there is no way around this. Write your password down somewhere if you can't remember it.

You're running more than the specified power. The refrigerator is an inductive load, which means the power factor Pf will be less than one. Consequently, the power draw from the inverter is Volts x Amps / Pf. Also, if the inverter voltage is less tan 120V, the refrigerator's compressor and fan motors will draw more current than the nominal rating. How much more depends on the motor design. The harmonics from the inverter (it has anon-sinusoidal input) may increase energy loss in the motors, especially if there is a fan with a shaded pole motor (common in refrigerators). The bottom line is that you are probably drawing at least 420 Watts from an inverter rated for 410 Watts. It's very close to shutting down on you, and may cause premature failure in the refrigerator.
I recommend getting an inverter with at least 450 Watt capacity, preferably with a true sinusoidal output, or harmonic content less than 5% under full load..

Hi Jeremyb01,

Our online store operates with separate pricing and promotions than the Best Buy™ stores. A sale price online does not necessarily mean the item is on sale at the store. However, if you choose store pickup rather than delivery, you will pay the lesser of the two prices when you pick up the item and complete your order if the prices differ. Also, Best Buy™ stores will match a price shown for our own online store if the item is available currently for a lesser price.

Thank you,
Jason,
Go Ahead. Use Us.

The reasons for the generator dose not generate electricity are as follows:
1, the magnetic pole of the generator loses magnetism;
2, the excitation circuit component is damaged or the circuit is broken, short circuit or grounding phenomenon;
3, the exciter brush has bad contact with commutator or the brush frame pressure is insufficient;
4, wrong connection of excitation winding, opposite polarity;
5, poor contact between generator brush and sliding ring, or insufficient brush pressure;
6, broken circuit of generator stator winding or rotor winding;
7, loosening of generator lead wire or poor contact between switch and wire; Fuses, etc.
