I just got a refurbished laptop that i ordered on Ebay a couple of weeks ago. it’s a Lenovo X230 with an i7-3520m, with a 256gb ssd and 8gb of ram which i bumped already to 16gb. I decided to go for this laptop as i was pretty affordable and it was in a pretty good condition and didn’t need to do a whole lot of upgrades, besides the RAM and the screen which is a TN one. Also i was looking for a lightweight option to carry to the university or anywhere easily.
When it arrived it was a bit dusty and came with a Windows 10 installed… After a cleanup of both the OS and front and back lid (still with a scratch at the front..), i went for installing a debian buster. After 10mins i got my linux up and running.
Did some tests to check the thermals and apparently i got about 49C on idle and 85C on full load, so i’ll leave the repasting for next month.
i was a bit concerned about the battery, which could be a lottery ticket when buying a second hand laptop, the one it came with is a 6-cell battery 44+ lenovo one, and after running this command to check the battery status:
upower -i /org/freedesktop/UPower/devices/battery_BAT0
and got the following output
native-path: BAT0 vendor: LGC model: 45N1025 serial: 74 power supply: yes updated: Mon 09 Dec 2019 11:24:33 PM -03 (41 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging warning-level: none energy: 45.65 Wh energy-empty: 0 Wh energy-full: 45.65 Wh energy-full-design: 57.72 Wh energy-rate: 2.437 W voltage: 12.567 V percentage: 100% capacity: 78.7422% technology: lithium-ion icon-name: 'battery-full-charging-symbolic' History (rate): 1576203873 2.437 charging
where apparently the capacity left on the battery is a bit les than 78.75%, which is pretty good so far. I’ve got about 4-5hr mark with a light use (visualstudio code + browser), so i’ll probably start looking for a new 6 or 9-cell battery later on next year, for now i think i’m pretty fine with this one.
So far i’m pleased with my laptop and hope to upgrade soon, probably next month the display to an IPS one.

Last week i wanted to update some ruby projects that i have packed in gems and wanted to update their dependencies (just to have the project updated). My objective was to be able to update all my gems in a single bash line, luckily i managed to do this by issuing the following line:
