Acer Aspire One charge light does not light up and battery does not charge

My Linpus Acer Aspire One was laying idle for a few months, then I pulled it out to use it, and was dismayed when it would not charge. The orange battery charging light would flash for a second, then turn off.

Problem 1: The Acer would not power up with the AC adapter.

After scanning the web for a while, it appeared there were several possible reasons for this:

  • Bad battery
  • Bad AC adapter
  • BIOS update needed
  • Loose jack on the motherboard, necessitating service.

The easiest possibility to deal with was to assume that the AC adapter cable had gone bad so I ordered a new one. Fortunately they are inexpensive. I found one through Buy.com for a total of $19.84 including the shipping and handling.

Infinite JW FLV players on a page, with error catching for Red5 bug

NOTE: this has been revised to make it more flexible, and allow multiple streamers and multiple video types, using the same code.

This is a script that allows you to add as many JW FLV players to a page as you want, using a single block of code. The players all have separate event listeners to keep them from interfering with each other. Events or actions executed in one player do not affect others.

This particular demo also corrects for a problem we have noticed recently with Red5, where RTMP streams will hang with a “BUFFER.EMPTY” status code. I’ve set up meta-monitoring so that it catches “BUFFER.EMPTY” codes and starts the player up again a little bit previous to the break. It creates player names and function names dynamically, based on how many players you request. If this function seems to be giving you problems, if your videos start jumping back and restarting a lot, search for the following line and comment it out by adding “//” in front of it:

window["player_"+obj.id].sendEvent('SEEK', parseInt(window["positionarray_"+obj.id][3])+100);

We’ve also had problems with some videos that simply refuse to stream, although they will play using progressive download. You can use a mixture of streaming and non-streaming by altering the playlist for each video.

JW FLV Player and Red5 apparent buffering bug

Update 12-18-09: Longtailvideo has apparently resolved this bug with its player v.4.7beta. At this time v. 5 does NOT have the fix in it. The code changes that fixed the bug can be seen here: [Changes to RTMPModel.as]

A few months ago, we installed Red5 0.7.0 on a Windows server to stream Flash video inside the firewall. This server is used mainly to stream short clips that are embedded in learning modules.

The JW FLV player v. 4.6 is included in the learning module template and enables us to display the videos with a high degree of flexibility.

The player generates a navigation listing on the right from the XML playlist.
