Einleitung

If your Asus Eee PC 900 LCD display screen is damaged, experiencing pixel issues, or is dim in a bright background, use this guide to replace your display screen.

Prior to making this repair, it is important to confirm that the replacement itself is necessary. Check to make sure that no other solutions are viable. For problems such as pixel issues, inverter issues, or not being able to see color, a full replacement may be necessary.

This guide requires you to remove the battery, keyboard, top cover, and LCD display screen from your Asus Eee PC 900. Some steps require the use of a spudger.

Before beginning, make sure to completely power down the device and disconnect from any external power source.

Werkzeuge

Schritt 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.

Schritt 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?

Schritt 3

Caution Follow this step to detach the upper portion of the keyboard, but do not remove it from the laptop. Damage to the keyboard's ribbon cable may result if improperly executed.
Identify the three metal tabs holding down the laptop's keyboard.
Using a spudger, depress each metal tab to remove the keyboard.
The upper part of the keyboard should "pop up" from its holder.

Schritt 4

Clips hold the bottom portion of the keyboard to the laptop. Gently lift the upper portion of the keyboard and then move the entire keyboard towards the computer's screen until the ribbon cable is visible.

Schritt 5

Using a spudger, gently push the two black pins holding the ribbon cable towards the computer's screen.
Slide the keyboard's ribbon cable from the connector.

Schritt 6

Remove the keyboard by lifting upwards.

Schritt 7

Remove the nine 4.76mm Phillips #0 screws on the top cover of the laptop.

Schritt 8

Remove the six 4.76 mm Phillips #0 screws on the back of the laptop.

Schritt 9

Flip the laptop back over and identify the touchpad ribbon.
Unlock the tan locking pin from the black connector by pushing the pin to the right with a spudger.

Schritt 10

Slide out the touchpad's ribbon connector by pulling the blue tab to the right.

Schritt 11

Use a plastic opening tool to gently detach the top cover from the laptop's base. See the next step for removing the cover.

Schritt 12

Caution: To clear the audio and microphone, lift the right half and move the cover to the left (as shown in the second picture) to prevent cover damage.
Remove the laptop cover.

Schritt 13

Remove the large black wire using a plastic opening tool.

Schritt 14

Gently pry off the six rubber covers around the outside of the screen using a two mm flat head screwdriver.
A flat head screwdriver is preferable over a spudger as the spudger's head is not thin enough to to slip under the rubber covers.
Remove the six 4.76 mm Phillips #0 screws underneath each cover.
