ASUS UL80Vt and G51J: Going for the Gold

ASUS UL80Vt Battery Life
The coup de grace for the UL80Vt is the battery life. Look at those charts and try to find anything else for $800 that can match the ASUS UL80Vt. (Note: the ASUS UL30Vt doesn't count, since it's pretty much the same laptop in a slightly smaller package.) Netbooks are able to offer competitive battery life, sure, but they're less than half as fast. The best-case Idle battery life tops out at just over 14 hours, but even a more demanding test where we load four web pages every 60 seconds - including one page with three Flash ads - still ends up at nearly 10 hours using the IGP and stock CPU speed. What's more, you can run with Turbo33 and the G210M and still get over 6.5 hours of web surfing.
We've dropped the other video playback tests, mostly because they're all very similar to the x264 results. HD DivX will last about 10-15% longer, and lower resolution videos would also improve on the results, but in general you can expect 5 to 6 hours of video playback with the UL80Vt.
The relative battery life is the final element, putting things into perspective. The UL80Vt has a higher capacity battery, so getting more mobility is somewhat expected. In the lowest power mode (IGP + stock CPU) the UL80Vt can provide nearly seven minutes per Wh, which is just slightly less than the ASUS 1005HA netbook. Turn on Turbo33 and battery life drops by about 10%. Running stock with the G210M enabled on the other hand results in a drop of 46%. Internet surfing with Turbo33 + G210M doesn't really change compared to stock with G210M, with only a 1% drop. The results here are in a test that happens to be more demanding than our MacBook testing, so the stellar battery life is even more impressive. Is it any wonder we're impressed with the ASUS UL80Vt? You get awesome battery life with reasonable gaming and application performance, all for just $800.

you say you adjust the critical battery percentage to 1%. while on a battery test thats perfectly ok, i heard (tomshardware) and painfully experienced that discharging a battery to zero is very bad for the cells.one time vista didnt shut down in time and the battery lost about 20% of its capacity.
however, it would be great, if you guys made a battery guide/test and scientifically research the dos and donts of batteries. these little chemical friends are the cornerstone of our digital and mobile lifestyle, it scares me, how little proven knowledge exists on this topic.

This is AT. The first thing you should do is a clean install since your readers aren't going to keep all the OEM crapware on the machine.I'd also say to make sure you're using the Advanced settings in both Vista and WIndows 7, and with Windows 7 you need to disable any sleep/wake timers.

All the OEM software (other than useful utilities) gets removed/disabled, but doing a clean install every time has its own set of pitfalls. I try to review laptops as the users will get them, and a clean install every time is a bit much. Regardless, this has happened on clean builds as well, so the bloatware you refer to may aggravate the situation somewhat but it's not the root cause.As for the Advanced settings, obviously I've gone in there when I discuss things such as prompt for password being reset (to "Yes"). The odd thing is that it's only a subset of settings that get reset. The min/max CPU percentages stick, WiFi power settings stick, and so do most of the settings in the "middle" of the advanced power options. It's the first few settings and the last couple that seem to revert on a regular basis. The UL80Vt for example reverts once or twice a day -- one of the worst offenders in my experience.

I've had it happen fairly often on both Vista and 7, after perfectly clean installs, with no third-party power software. Do not require password on wake creeps back up every so often, as does do not enter sleep mode on lid close if on AC power, even though I've repeatedly disabled them both.danwat1234 - Thursday, August 14, 2014 - link
The Asus G50VT-X6, the predecessor to the G51J is very sexy. Very speedy with a cheap X9100 CPU you can buy on Ebay. Put in an SSD, buy a few extra genuine 9 cell batteries on Ebay and stick them in the fridge so you'll have a good batteries for the next 7+ years and your good.It does run hot but that's ok. It is a part of it's personality. I am waiting until Per core x86 performance of the latest mobile chips are over twice the speed (work done) of my existing laptop. I think I'll wait until 11nm skymont.
In regards to longevity, I've been crunching on the 9800gs video card and the CPU for years and years with Seti@Home nearly 24/7 with no failures. This thing is reliable. I have burnt out quite a few AC adapters though. DC jack is solid. Running at 85-90C on the GPU most of the time and it really doesn't care.

I really liked this part of the article, you need more publicize this so many people who know about it are rare for people to know this, Success for you. You May Like to check <a href="https://www.epsondownload.net/epson-xp-310/"&... xp-310 software</a>
