I think the filler is useful to give the laptop increased mechanical stiffness and better balance. And the primary hazard is with charged cells. However uncharged batteries still might have some charge in sections (and hold it for a year or so), and in any case there is a lot of lithium...

Upon battery insertion the battery manager board, if working, momentarily test charges the cells and looks for approximately 3V= If this is not met charging is disallowed and the battery would not be recognized nor connected to the laptop for discharge. Of course if the battery manager itself...

Now I can't save as QT movie and then try to open it like you did because the QT plugin under all three browsers asks me to pay for QT Pro upgrade, but I did try all three browsers with the link extracted from your movie screen...

I'm thinking the problem is Quicktime plugin being stupid under Safari... My Pismo 10.3.9 400 MHz PowerPC G3 256 MB SDRAM Trying to play your movie on your problem, by viewing your post from the following browsers and clicking on your link: Safari 1.3.2 plays sound only Firefox 2.0.0.16...

http://www.vintagemacworld.com/drives.html That drive looks like one in an old 1993 Apple Catalog intended for connection to an Apple IIe Card for Macintosh used with the LC,LC II, LC III, or Color Classic that would run Apple II programs.

You can look in your user library folder for the Quicktime preferences file(s). Perhaps there is an out of date duplicate or corrupt copy, and purging them forcing Quicktime to create a new file might help. Failing this, a disk diagnostic followed by a reinstall of Quicktime might be a...

Something similar happened to me once. I had connected the switch cable upside down so the common wired side of my switch connector acted as all jumpers connected so long as the switch was set to any number asserting at least one connection.

Yet another area to check...The video from the logic board passes thru a single 74LS38 buffer, U1, on the analog board (and pullup R1 and series terminator R30) before being passed on to the CRT mounted video board. U1 also buffers the vertical and horizontal drive into the analog board. R28...

[8)] ]'> I just noticed that the low level signals to and from the heads are carried by flex PC conductors terminating in tin plated connections (at least on my current SE/30 reference unit). Over time, this is known to be NOT GOOD, leading to intermittent and/or poor connections. To test...

My two cents worth: You can test to see that the heads make sufficient mechanical contact for reliable operations (I'm assuming you have already successfully tried a known good floppy drive in each of your machines to eliminate bad floppy controllers, cables, power supplies, and possibly...

You can test the Lombard internal fan by itself. Disconnect it and make a drawing of the three wire colors and where they go into the plug housing. Then if necessary remove the connector pins temporarily from the plastic block with a jeweler's screwdriver and power up the red and black to...

So now you can go inside for a look! First push up the docking door and look to see that there is no metal debris shorting out the docking contacts. Verify the battery contacts are clean on both ends of the battery bay. Then remove the four self tapping screws, pull the stylus part way out of...

Verify that there is a good solid ground path from the crt safety band mount to the analog board ground, close to zero ohms. Viewed from the rear, the ONLY path is from the upper left band mounting screw thru the terminal lugged black/white wire to the B/W pad on the upper left corner of the...

PM sent. Let it charge at least 4 hours. It still could have a capacity and internal drop problem, but a full charge will give it the best chance of running the machine. My understanding is that the gas gauge inside the battery is not to be trusted even a little until it has cycled thru a...

The batteries age by increasing their internal impedance (voltage drop under load) as well as by capacity (amp-hours) loss. They can show a fairly full gas gauge (reasonable no load voltage) but get drawn down under load quickly-this could explain your machine running only briefly. So after...

Try the battery in the right hand expansion bay with the machine first running on AC also, and again ignore the status icon and just pull AC power to see if the Lombard switches over to battery power. It is probably best to have charged up the PRAM battery for 48 hours before the switchover...

Well, should you want to try the shorting trick be sure to check for very low energy on those terminals first, we do not know that all packs will be in a safe cooperative state! Maybe a pulldown resistor might be better than a wire to start. Although I am pleased to have rescued one battery...

Recently I re-celled a pack for my Pismo, and noticed initially that the machine would not startup at all, not even momentarily, from the fully charged pack. I had previously tried some firmware resets to the pack prior to re-celling as discussed in http://www.maclife.com/forums/topic/51129/1...

Could be, but give it a chance to heal (recharge). I was sure the PRAM battery was hosed on the PBG3 Firewire I just bought, but then I pulled the dead main battery to do some surgical inspection inside it. With the main battery out and the 0% charge symbol replaced by the little AC plug...
