This guide aims to provide some assistance <strong>and</strong> tips for a DIY replacement of the back up battery for the<br />

hx2000 series <strong>iPAQ</strong> (hx2110 / hx2115 / hx2410 / hx2415 / hx2750 / hx2755 / hx2790 / hx2795).<br />

A faulty back up battery is often to blame for a wide range of <strong>iPAQ</strong> memory issues such as the loss of all<br />

data <strong>and</strong> custom settings when the unit’s power runs down, a replacement back up battery will cure your<br />

unit of its temporary amnesia.<br />

Required Tools<br />

• A Torx size 6 (T6) Screwdriver (available here in the tools section of the website, suitable for all<br />

models).<br />

• A new back up battery for the hx2000 (available here).<br />

• A small crosshead screwdriver.<br />

Stage One – removing the battery<br />

It is advisable to back up any important data currently held on your <strong>iPAQ</strong> unit, once you are ready to begin<br />

prepare a clean <strong>and</strong> safe work surface in order to protect your hx2000 screen when the <strong>iPAQ</strong> unit is face<br />

down. The first step is to remove your stylus, compact flash card, screen cover <strong>and</strong> battery. To remove the<br />

battery cover <strong>and</strong> battery from the unit press in the release button on the battery cover <strong>and</strong> then using the<br />

top left corner of the battery unit release it from the battery position.<br />

Stage Two – removing the case<br />

The next step is to remove the back case, begin by unscrewing the four screws on the lower back panel<br />

using the Torx screwdriver.

---

Once you have removed these screws you can now take off the rubber grips on the side of the <strong>iPAQ</strong> –<br />

simply push the grips away from the unit <strong>and</strong> these should come away easily.<br />

With the rubber grips removed you can now unscrew the last two screws, located on both sides of the top<br />

case. Please be aware that opening your <strong>iPAQ</strong> unit will void your official <strong>HP</strong> warranty.

---

The case is now ready to come off, simply pull the front case away from the back case from the bottom of<br />

the unit.<br />

Step Three – disconnecting the mainboard<br />

To access the <strong>iPAQ</strong> back up battery you will need to remove the mainboard, this involves disconnecting a<br />

number of components (see picture)

---

The first step is to disconnect the cable connectors on the right h<strong>and</strong> side of the unit, these cables simply<br />

pull away from the socket.<br />

Disconnect the cable connectors on the left h<strong>and</strong> side of the unit also.

---

Disconnect the Screen cable by simply pulling the connector away from the socket.<br />

With these components disconnected you only need to unscrew the top two screws, after this the<br />

mainboard is ready to take away from the unit.

---

As the headphone socket (in the top left of the unit) also holds the unit into the case you will need to pull the<br />

mainboard downwards <strong>and</strong> away to release it from the front case. When removing the mainboard be aware<br />

that if your unit features the white WiFi cable you do not need to remove this in order to access the battery –<br />

it is long enough to allow you to replace the battery without disconnecting it.<br />

Step Four – replacing the backup battery<br />

You are now ready to replace the hx2000 backup battery; this is simply held in place by an adhesive glue<br />

spot. Remove the old battery, <strong>and</strong> fit the replacement in the same position using the adhesive spot.

---

Stage Five – unit reassembly<br />

With your new battery fitted you can now begin to reassemble your unit! Reposition the mainboard firstly by<br />

levering the headphone unit into the headphone socket <strong>and</strong> then laying it into position. Using Stage Three<br />

as a reference reconnect the three push connectors, screen cable <strong>and</strong> refit the two screws. Before you put<br />

the back case on be sure that there are no cables that may get snagged between the case assembly. Once<br />

you are sure that all components <strong>and</strong> cables are safely connected, affix the back case.<br />

You can now put the rubber side grips on the unit – be aware that the rubber grip with the Record Button is<br />

the left grip (as the screen faces you). With the battery <strong>and</strong> battery cover back on you have successfully<br />

completed this simple replacement! Now be sure to charge your unit fully (until the orange charge light is<br />

constant) <strong>and</strong> your hx2000 <strong>iPAQ</strong> is ready to use!<br />
