Introduction

RAM acts as temporary storage on your device that will occasionally fault or run out of memory. If you need to replace or install new RAM on your Asus Eee PC 900, follow the directions below. Before beginning, make sure the device is powered off and is not connected to any power source.

Step 1

Slide the battery's locking tabs from the locked position to unlocked positions.
The right tab is unlocked when a red dot is showing.
The left tab will have to be held in the unlocked position in order to release the battery.

Step 2

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?

Step 3

Remove the sticker from the RAM compartment using a pair of tweezers.

Step 4

Remove the two 4.8 mm screws using a Phillips #0 screwdriver.

Step 5

Open up the cover from the bottom by carefully prying it open with a plastic opening tool.
Be gentle when prying open the cover in order to not damage it.

Step 6

Remove the back cover by pulling up on the side that had the screws.

Step 7

Use a spudger to push the top of the pin on the right towards the right (so it isn't holding the RAM chip).
Do the same for the left pin. Push the top of the pin towards the left.
The RAM should pop up.

Step 8

Remove the RAM chip by grabbing the top of the chip and pulling it upwards.
Be gentle when removing the RAM because it is a very delicate part and you do not want to break any of the pins in the computer.

Conclusion

To reassemble your device, follow these instructions in reverse order.
