Slide the battery's locking tabs from the locked position to unlocked positions.

Slide the battery out while holding the left locking tab in the unlocked position.
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…)
or need a bridge at the connector to see realbatterypackvoltage there… check it out
good luck, thomas@biopilze.de
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!
>>…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?

Where is STEP 2 1/2? my keyboard dosnt just fall out nice, how do you remove the keyboard?
Yeah I don't know how to remove keyboard. Also once I get to step 14.. What do I do? You tell me how to identify the broken piece but is it replaceable or fixable?
