HP530 Disassembly and Cleanup

HP530 Notebook PC.

This HP 530 notebook is a nice computer. After almost 4 years of use it was running its Ubuntu Karmic very hot and the fan was somewhat noisy. I also remember to have read somewhere that it should be cleaned at least once a year, so I decided to take it apart. I didn't initially plan to create an article or post any information, so the photos were taken after it was fully dismantled and when reassembling it.

This is a quick disassembly and cleanup guide.

WARNING: This guide assumes that you are an experienced technician! A mistake could possibly render this computer useless.

Besides cleaning it, I also wanted to know if it was possible to add the Bluetooth module shown in the photo below, it is from a USB dongle, but despite the ICH7 being capable of handling 8 USB ports (with only 2 external ports available in this computer) the extra USB port's pins don't seem to be connected to an accessible pad. What a shame.

This article is intended to be a quick full disassembly guide. The service manual can be downloaded directly from HP, from this link but it's a long read compared to this guide. It can be useful if you only plan to remove a single part.

It's important to use a grounded antistatic wrist strap during all the procedure and to put the sensitive parts that you remove (memories, modems, motherboard, etc) in antistatic bags. Only light efforts are required to remove the parts, so if something seems to require considerable force, check everything again to make sure that you didn't forget anything, such as removing a screw. It can also be the case that some sticky stuff has been spilled inside.

(1) Disconnect everything and remove the battery.

(2) As I wanted to completely take apart the bottom of this notebook, I removed every single of the screws in the bottom. Remove the bottom covers, the CD/DVD writer, then the hard disk which can be pulled from a plastic tab to the left as oriented in the picture below. Disconnect the antenna cables.

(3) Remove the top cover. There are some plastic clips and the area marked in the smaller squares must be lifted first.

(4) Remove the keyboard. Lift and slide the keyboard towards the screen. Be careful with the connector ribbon. Very carefully unlock the connector and pull the ribbon.

(5) Disconnect the mouse pad, carefully pull the wireless radio antenna cables and remove it from its guide channel, pull the monitor connector and remove the cable from its guide channel, disconnect the top button PCB. Remove the LCD hinges screws and remove the screen.

(6) Carefully separate the top and bottom, the motherboard is attached to the top cover.

(7) Remove the fan screw, the fan connector and lift the fan. Remove one motherboard screw, the speaker connector, four PCMCIA cage screws.

Now you can lift the motherboard. Note that I could lift the mother board without removing the heat sink. It's better to not remove it as later it would be necessary to make sure that the thermal pads are totally clean or even replace the thermal pads.

Now it's possible to clean all.

Is any of those vias/pads connected to the very desirable extra USB ports' pins? If you know, please tell me.

To reassemble, just follow the previous steps in reverse order.

After reassembly, the computer ran more silently and more importantly, rather very cool at high loads! Before cleaning it, some of the readings where near or slightly above the “crit” values.

Conclusion

This is definitely a very nice notebook, probably it's really necessary to clean it once a year. The worst limitation of this computer is that it only has two USB ports and looks like it isn't possible to access the additional ports that are built into the chipset as I've seen from some ASUS EEE modders' work.

A funny thing that I observed is that the CD/DVD writer has a working busy/access LED, but there is no light pipe to the outer case. I know that that's for economy's sake but this computer could certainly use a few more external indicators.
