OS Installation & Battery Service FAQs
Will my personal files on D: or E: drives be deleted during Windows 10/11 installation?
No. We strictly format only the system partition (C: drive) and also back up your Desktop, Documents, and Downloads folders before reinstalling Windows or Linux.
How long does an OS installation or battery service take?
Standard Windows 10/11 Pro installation with full drivers and Office software takes 45 to 60 minutes. Laptop and UPS battery replacement takes 30 minutes, while custom lithium pack cell-balancing takes 1–3 hours.
Do you provide warranty on laptop and UPS batteries?
Yes! Our replacement laptop batteries and 12V UPS batteries come with up to 6 months official replacement warranty along with free charging voltage diagnostics.
Can you install Linux or dual-boot Windows + Ubuntu on my laptop?
Absolutely. We configure UEFI dual-boot systems (Windows 11 + Ubuntu / Linux Mint) as well as headless Armbian Linux servers on TV boxes.
