The GT610 is more powerful than the GT210 and still very cheap. It works out of the box on 10.8.3 or later including Mavericks. On the passive (fanless) cards such as the MSI 2GB one, I had to dremmel the heatsink slightly for it to fit in the 755 because of those 2 capacitors mentioned earlier...

I have tried 2 different versions of the Belkin F5D7001. Only one of them worked. The version 1101UK does not work while the 1323UK is detected as an Airport card. On Belkins website, they list 3 windows drivers: 1xxx, 13xx adn 2xxx version. I assume that is because the F5D7001 comes with 3...

I had no problems going from an dual E4300 C2D 1.8GHz to an quad E5450 XEON 3GHz on an Asus P5KPL-AM. Have you tried running windows or linux on it? This might be unrelated but: I did get a problem when going from an NVIDIA GT610 to an NVIDIA GT640 on the same system. Both of those cards...

Well I don't want to exacerbate your exasperation, but a complete fresh install on the SSD might be the quickest resolution. You will have to solve all the hardware issues yourself, but it will be a known quantity and starting point. It might be a useful exercise because when software update...

If you have a 1600x900 screen then you can fit a 1920x1080 panel without replacing the cable.

They both have exactly the same motherboard, so I would choose purely on your preference for 15" or 17". All 4530s's come with 1366x768. Some, if not all 4730s's come with 1600x900. Both laptops can be upgraded to 1920x1080 LCD's.

Try going into network preferences and deleting the physical connections on the left by clicking the '-' icon. Then add the ethernet followed by wifi. If that does not work, delete /Library/Preferences/SystemConfiguration/NetworkInterfaces.plist and reboot.

4540S LCD Screen Does this apply to all their laptops? I bought a dual link screen cable 2-3 weeks ago.

No, only Sandy Bridge in the 4530s. The 4530s has an Intel HM65 chipset which supports gen 2 Sandy Bridge processors. The 4540s has an Intel HM76 chipset and this supports both gen 2 and gen 3 (Sandy and Ivy Bridge) CPU's.

Make sure you have a small TORX screwdriver to hand before sitting down to disassemble. The 4530s comes apart very nicely for a laptop. If you haven't taken the keyboard off before, be gentle because it is stuck down with double sided sticky pads and it flexes and bends easily while trying to...

I believe all Sandybridge core i3/i5/i7 CPU's work fine in the 4530s. Just make sure you stay away from ES (Engineering Sample) and QS (Quality Sample) chips. They may be non standard or have instructions missing. Also, if you put a chip in that is not included in the Probook Installer, you will...

Reading from the chip was reliable but writing was inconsistent. I test wrote 1 byte to a large area of 0xFF's around 0x150000 (way before the 68SRR.BIN start). I only managed to write once to that area and I was not able to work out why I couldn't repeat it. When I wrote to the 3 address ranges...

I searched through the entire BIOS file and found a few areas of text such as "HP Bios User 00 BIOS Administrator" in what appeared to be a table. Between these references are strings of data which always end with "AA 55 7F". I made an educated guess that the strings of data contained the...

First of all, THANK YOU big donkey for the information you put in this thread. You have provided me with some of the puzzle pieces to overcome a recent laptop problem. I just want to add some information that might help other hackintoshers. I recently bought a used Probook 4330s with most...

I agree. a few possibilities exist: 1) I have a motherboard problem that only exhibits itself under ML when 2 sticks of ram are installed. 2) There is something specifically incompatible between this Samsung ram when in any combination of 2 sticks under ML. 3) ML just doesnt work on this...

Look closely at the photo in post #1 and you will see that the top stick is upside down to show the sticker underneath. This is to show what both faces of the stick look like for the benefit of the community. This is obviously a rare problem but at least one other person has experienced it. I am...

That picture shows a matched pair actually ........... :)

The original 2x4Gb are an exact matched pair. It is these that have caused the problem all along. The memory has been fully tested and it is not ay fault. There is just the incompatibility with OSX that is the problem. I only have 1 other stick of ram that fits this laptop. Any combination of 2...

I have always had 8Gb (2x4Gb) installed until tonight. My custom DSDT was patched with the 2x4Gb ram cards in place. The ML install is only smooth and consistent with 1x4Gb installed, irrelevant of what DSDT is present. Focusing on DSDT in this case is a dead end. I would add this to the FAQ...
