Power Issues with your laptop

This guide is intended to troubleshoot and resolve booting issues with your laptop. At the end of this troubleshooting guide you should know why your laptop will not longer turn on.

■ Start with a Hard Reboot
Remove the battery and unplug it’s AC adapter then press and hold the power button for 20 seconds then try booting it.

■ Change your Power Source
Try to boot your laptop without its battery and just use its AC adapter as a power source.

■ Re-seat the RAM
If the above did not resolve your issue, please re-seat the RAM. Remove the RAM sticks for a couple of seconds then re-insert them, making sure everything is seated properly.

■ Connect to an External Display
If you can hear the laptop is on, but there is no graphics on the display, please connect your laptop to an external monitor and see if it will display anything. If the external monitor displays your laptop’s graphics your laptop screen may be faulty.

■ Test another AC Adapter
See if your AC adapter is working properly. You can test this by trying another AC adapter that has the same voltage.

■ Service and Repair
If none of the above works it could be a motherboard problem. At this point I would recommend to bring your laptop in for service and repair.

Best Graphics Cards for Gaming in 2024

The best graphics cards are the beating heart of any gaming PC, and everything else comes second. Without a powerful GPU pushing pixels, even the fastest of the best CPUs for gaming won’t manage much. No one graphics card will be right for everyone, so we’ve provided options for every budget and mindset below. Whether you’re after the fastest graphics card, the best value, or the best card at a given price, we’ve got you covered.

Where our GPU benchmarks hierarchy ranks all of the cards based purely on performance, our list of the best graphics cards looks at the whole package. Current GPU pricing, performance, features, efficiency, and availability are all important, though the weighting becomes more subjective. Factoring in all of those aspects, these are the best graphics cards that are currently available.

We haven’t had a ‘new’ GPU launch since February’s RX 7900 GRE, joining the four GPUs that came out in January: RTX 4080 Super, RTX 4070 Ti Super, RTX 4070 Super, and RX 7600 XT. All of these are in our performance charts, and some make our overall picks, replacing former entries that are now discontinued.

Barring a surprise announcement in the coming months, this should be the end of new models until the future Nvidia Blackwell and RTX 50-series, AMD RDNA 4, and Intel Battlemage GPUs arrive — most likely in the fall of 2024, though that remains to be seen. The closest thing to new GPUs is Nvidia’s SFF-ready GPU specifications, but those likely sacrifice some performance to fit into a smaller volume.

Prices are mostly sitting at MSRP and below for the least expensive offering on each GPU. That includes the RTX 4080 Super at $976, though the cheapest RTX 4090 costs $1,730 right now — may as well wait for the RTX 5090 at this point. That advice applies to most of the high-end cards: If you haven’t already upgraded, waiting until October/November to see what becomes available makes a lot of sense.

Optimizare ZFS pentru RAID în Linux

În lumea administrării sistemelor de operare, ZFS (Zettabyte File System) a devenit cunoscut pentru robustetea și flexibilitatea sa. Acesta combină funcționalitățile unui sistem de fișiere și ale unui manager de volume într-un singur pachet, fiind ideal pentru soluțiile de stocare RAID (Redundant Array of Independent Disks).

Ce este ZFS și RAID?

ZFS este un sistem de fișiere de mare capacitate, creat inițial de Sun Microsystems pentru Solaris și disponibil acum și pe Linux. Este cunoscut pentru verificarea integrității datelor, suportul pentru snapshot-uri, compresia transparentă și alte funcții avansate.

RAID este o metodă de a combina mai multe discuri într-un singur sistem de stocare pentru a oferi redundanță și/sau performanță. RAID poate fi implementat în mai multe moduri, cum ar fi RAID 0, RAID 1, RAID 5, RAID 6 și RAID-Z (o implementare specifică ZFS).
