Sony's 2001 VAIO PCG-SRX: a 1.26kg B5 notebook with a Pentium III-M inside

A first-person retrospective on Shaoshupai revisits Sony's late-2001 VAIO PCG-SRX, a B5-size notebook weighing about 1.26kg, and documents what it takes to revive one decades later.

The article describes the SRX as a full generational replacement for Sony's earlier SR series rather than a naming refresh. Citing Sony product pages, it says the first SRX machines went on sale in Japan in November 2001 in three configurations. The entry PCG-SRX3 used a 650MHz Intel Celeron with 128MB of memory and a 20GB hard drive; the SRX3/BD carried identical hardware but shipped with an external CD-RW/DVD-ROM drive; and the top PCG-SRX7 stepped up to an 800MHz Pentium III-M, 128MB of memory and a 30GB drive. All three supported 2.4GHz Wi-Fi and ran Windows XP Home Edition, but only the SRX7 included built-in Bluetooth.

For comparison, the piece notes that IBM's 2001 ThinkPad X22, a 12.1-inch TFT machine at 1024x768 with a Pentium III-M running at 733MHz or 800MHz, weighed between 1.6kg and 1.7kg.

The unit examined in the article is a PCG-SRX7 that arrived in unusually clean condition, with no obvious scratches on the shell and little visible wear on the keyboard. The lid carries a bright silver coating, while the B and C surfaces use the blue-purple that marked Sony's VAIO line at the time. The palm rest is made of semi-transparent polycarbonate, so the power and hard-drive indicator lights shine through as a faint blue-purple glow in low light, a detail the author says was widely discussed by users at the time. Instead of a pointing stick, the SRX used a circular SmartPad touchpad, with Sony's Jog Dial rotary control sitting below it; through Sony's drivers the dial scrolls pages and integrates into the operating system, and it can also adjust volume and brightness together with the Fn key.

Sony fitted the notebook with a "cascade cooling unit" built around very thin heat pipes and a rearranged internal layout, which the article credits as one reason a relatively strong processor of the period could be packed into a 10.4-inch chassis at 1.26kg. A removable battery, a fan exhaust and a quick-access hard-drive bay sit on the underside.

As received, the machine had 256MB of memory and Windows XP Professional in Simplified Chinese, with almost no third-party software installed. The author found the keyboard shortcuts and the Jog Dial unusable because Sony's own driver layer was missing. Restoring full function required installing more than ten drivers in a fixed order, obtained from the archive site VAIOLibrary; installing them out of sequence leaves some functions inactive.

Installing an operating system on the machine is difficult for a structural reason described in the piece: the SRX has no built-in optical drive, and although it has one USB port, its BIOS cannot boot from USB, ruling out external USB optical drives and flash drives. Sony's official external drive connected over i.LINK (IEEE 1394) rather than USB, and the company sold a small stand that let the drive sit upright.

Networking is limited by the era. The built-in wireless adapter supports only 802.11b and WEP encryption, while modern routers default to WPA2 or WPA3 and have dropped backward compatibility, so the card cannot join current networks. The author adds that system time and root certificates must also be corrected before a browser can load modern pages, and that the practical route online is the machine's own RJ45 port.

The article notes that the SRX sold in Japan with 2.4GHz Wi-Fi and Bluetooth, while the version offered in mainland China omitted both. It also records that the notebook appeared in the 2003 film Johnny English, where it was used on screen to assemble a suspect's image and to plot against the villain rather than as a passing prop.

In everyday use, the author reports that the speakers remain loud with a hint of stereo separation, and that running Office 2003 alongside Windows Media Player did not exhaust the 256MB of memory or repeatedly push the system into virtual memory.
