I recently inherited a very old Sony Vaio VGN-NR38M laptop; my wife is doing an online Masters degree, and wanted a laptop to do her coursework on. Unfortunately this thing is OLD. It was still running Windows Vista! And the battery was totally dead, so it only worked plugged into the mains, and if it got unplugged, instantly died. So, not much use then! Rather than write it off, however, I decided to see if it could be upgraded for a modest sum to make it usable.
The first step was to put a modern, secure OS on there – no way was I going to expose Vista to the internet! I decided to try Windows 10 32-bit; I had read that 64-bit drivers might not be available for some of the laptop’s ancient Sony hardware, and that 64-bit might be too taxing for it anyway. So, I downloaded a Windows ISO and made a bootable DVD using another PC. Unfortunately, although the Vaio would boot from the DVD, the Windows installation failed – it got stuck at a point looking for drivers. So, I borrowed an 8GB USB stick, and made a proper bootable USB installation using the Windows Media Creation Tool on yet another PC. This time, the installation worked! However, the laptop was unbearably sluggish, and would not make for a good user experience.
Next, I looked at RAM. The VGN-NR38M came with 2GB of RAM; I figured that if I could double that to 4GB, that should improve matters. So, I set to finding compatible RAM. Curiously though, the memory configurator websites all seemed to be of the opinion that the maximum installable RAM was… 2GB! The manual told you how to replace the RAM, but didn’t say anything about how much it would support. A bit more searching found some evidence that the maximum RAM might be 4GB, but that most people were unable to get more than 3GB working; a 1GB module in Slot 1 and a 2GB module in Slot 2. Since the RAM was very cheaply available, I purchased two 2GB sticks. When they arrived, I found that indeed, it seems Slot 1 can’t take more than 1GB RAM, annoyingly. So I now have a spare 2GB of RAM. With 3GB of RAM, there was little to no noticeable improvement, so I looked to the next possible upgrade.
The Vaio was fitted with a 250GB hard drive. Boot times were atrociously long. I decided to fit an SSD; this would speed up boot times, and app loading times, hopefully making the laptop bearable to use. So, I found a cheap 128GB SSD (the downgrade in capacity didn’t bother me as the laptop was only intended for my wife’s coursework, so no requirement for vast data storage). When this arrived, I used an Xbox 360 transfer cable that I had lying around to connect it to the laptop. It didn’t show up as a drive until I used Disk Management to format it. I used a cloning program to clone the HDD to the SSD. Then, I used this guide and a service manual I had found online to disassemble the Vaio and fit the SSD (the service manual is not for this exact model, and there are rather a few differences, but it’s similar enough). Note that it is NOT NECESSARY to remove the keyboard! Fitting the SSD was quite easy, and booting up with it installed showed a noticeable improvement! It wasn’t exactly fast, but it was an order of magnitude better than it had been, and on the verge of being decent. With that in mind, I decided it was worth spending a bit more on the next viable upgrade.
The NR-38M has a Socket P processor, which means you can remove and upgrade the CPU. It came with a T2390 Core 2 Duo running at 1.86GHz. That processor is a 65nm Merom CPU. The Vaio is limited by its FSB speed of 800MHz, so it won’t take any Socket P processors with a higher FSB. That means the very fastest processor you could fit is the T9500, which runs at 2.6GHz; however, T9500’s are very scarce, and quite expensive compared to the more common T9300, which runs at 2.5GHz. Since I didn’t want to spend too much on this project, I decided that the 0.1GHz difference wasn’t worth spending twice as much on a CPU that I’d likely have to order from China or the US. The T9300 is also a 45nm Penryn processor, which means it runs more efficiently and cooler! So that’s a plus. When I received the T9300, fitting it wasn’t too much trouble. The heatsinks for the CPU and the GPU are attached together with a heat pipe, so you have to remove both to get at the processor socket. I cleaned the old thermal paste off and applied Arctic Silver to the new CPU in place. (The GPU has a thermal pad applied; I considered removing this and replacing with Arctic Silver too, but due to the pad’s thickess, I decided against it. I didn’t want to be left with a GPU that wasn’t making proper contact with the heatsink!) On booting the laptop up, the difference was immediately obvious. It now booted in a snap, applications loaded almost immediately, and it felt pleasant in use! Hard to believe it was the same machine!
That just left the issue of the battery. The battery that came with it was a VGP-BPS9/B. There are plenty of third-party batteries to replace this available, but I’ve always been a bit wary of those; there’s even an official warning on the Sony website about not using non-official batteries, as they may post a safety hazard. I know most manufacturers would take the same tack, but even so, I still didn’t feel good about not using a genuine battery. Fortunately, there was one genuine – albeit used – Sony battery on eBay. This was a VGP-BPS10. The description advised that it was suitable for the VGN-NR series, and indeed it looked identical to the battery from my Vaio; the chief difference was that the VGP-BPS9/B was rated at 11.1V and 4800mAh, whilst the VGP-BPS10 is rated 10.8V and 5800mAh. I didn’t think the difference in voltage would be an issue, as my Vaio was now using an SSD instead of a mechanical HDD, and was running a 45nm CPU instead of 65nm, at lower voltage and cooling requirements. Also the larger capacity ought to offset the fact that the battery wasn’t new so might not hold a charge for as long as a new one would. So, I plumped for it. When it arrived, however, I found that it wouldn’t fit in the battery bay! Turns out that the VGP-BPS10 has a larger flange on it that the VGP-BPS9/B, presumably to prevent it being inserted into laptops it’s not designed for. Close examination of the two batteries convinced me that this flange was the only physical difference; the connectors were identical. So, I decided to whip the bottom shell off the laptop to see if the new battery would fit without the shell on. Once I got it off, the battery slipped right into place! With the shell loosely attached at the front, I powered the laptop on, and was pleased to see that the battery was recognised and started charging! So, I decided it was worth modifying the battery slot so that the BPS10 would fit. Looking closely at the bottom shell, it became apparent that I would only have to remove a bit of plastic in order for the battery to fit; it looks as though the mould was designed to be easily modified for future models to accept different batteries. A few cuts with a sharp knife and a bit of wiggling to snap the excess plastic off, and the battery bay now comfortably accommodates the new battery!
