Frequently Asked Questions

My laptop has liquid damage. Is it worth fixing?

In most cases, yes. Replacing a high-end MacBook or Gaming Rig in LA is expensive. Our component-level repair (microsoldering) is typically 30-50% cheaper than buying a new device. Plus, we aim to save your data, which a new laptop can’t give you back.

We serve clients, studios, and businesses across Los Angeles under strict data privacy protocols. Personal files are accessed only if necessary, and NDAs are available on request.

Standard diagnostics take 24-48 hours after we receive the device. Intermittent issues (like random crashing) may take longer to reproduce and verify.

Our diagnostic process includes a comprehensive assessment of your device to identify hardware or software issues. Our technicians will provide a detailed report and recommendations for repairs.

If you choose not to proceed with the repair, you can pick up your device with no additional obligations. The diagnostic fee remains applicable unless waived as part of a repair approval.
