general ideas:

-negative aspects:

* need for specific type of glue from "Therm‑a-Rest repair kit"

* Application of glue from the OUTSIDE

proposals:

* use of ANY type of glue for polyurethane -just at hand-

* application from the INSIDE: use a (BIG) needle and syringe: poke a hole near where the bubbles showed and bring in glue THERE...

>>…or need a bridge at the connector to see realbatterypackvoltage there… check it out

the connector has generally spoken: plus, minus, switch, thermal-control… some: ie2, too…

did that for a eeeepc900, external charge just at the connector, worked fine, now got eeepc900a, is different: one pin less, have to find out myself first… today did no more find any schematics in the web yet -any suggestions folks?

addendum:

if too old, too long lying at voltages under 3v… well possible that the liions wont keep the voltage, then at least one of two packs: (each two parallel 18650 liions) are gone -in that case you could try to dissassemble casing and replace a /or both pack/s, but is rather difficult: housing is a: well glued, try to open with sharpe knive but take extreme care not to destroy or short sircuit internals!!!!!! and b: is brittle and not much space for adding solder etc… -alltogether a thorny way…

you could just add external batteries at these poles, too… -if the originalones have just a high impedence/resistance, but do NOT leak (low impedence/resistance), otherwise constant energy-loss + heating… : problem: eeepc checks voltage-drift and regulates power-up/booster… if you added to much more voltage , as a flyby addendum: it rekocknizeses overload and shuts down imediately: so try to add batteries with similar voltage, possibly via a smal resisor first that buffers drain… give feedback to me please!

a (minor good, as liion batteries tend to degrade, esp in alltimeuse in bay: warm, max voltage=minimumlifespan) solution is:

try to revive the no more recognized one! first!!

either at the poles: need three connections: two at the ends, one in the middle like 1(+ -)-2-(+-)3

(need a hole through the casing/housing… (each of the two packs must be over 3.0volts: you can easily put a good charged liion from outside for a few moments to get a bit charge in to rise each pack over the 3.0 threshold that prevents pack of being recocknized as ok…)

good luck, thomas@biopilze.de

correction: white electrical-pvc-tape around -very firmly-..

> ...only the ...wire.... around the core was worn out...

so i soldered it together and wacked a slither of copper across the 'break" and put electric-pvc-tape around..

got no ibook, is for a friend:

could someone with a working one check the voltages at the contacts: i only read around 3 volts..! is it defect??

-well the magnetic-part can have an electronic to check whether the adapter really is attached to the device and only then give 20v power-

for the record

am waiting for further feedback...

to get to the right position it needs complete disassembly...

-dislike to procede opening the ebook to avoid unneccessary damage to the joints etc

especially theses delicate foil-connectors only have a limited number of in/out-cycles...

are others out there less hesitating? -yet am quite convinced its the way to go!

...that the line coming from the controller-chip is in the depth only...

-then we could still try to desolder just the right cs / ce - pin on each memory-chip!
