M4800 Owner's Thread

WX 4150 works well on M4800 without any issue.
and WX 4150 is on par with old K5100M card.

I received my eDP board today (C3V2K/LA-9772P) and installed it. It booted up fine and the new Samsung LTN156HL01-104 works beautifully. My conclusion is that the LVDS LA-9771P motherboards do not output eDP no matter what cable is used and I would advise against buying them.

Incidentally, the -104 variant of the above monitor is glossy, or is certainly not a matte in the sense that I'm familiar with. panelook.com doesn't have data on this criterion.
Edit: I was wrong; it is matte. The haze effect is much less pronounced than I am used to!

 

I've owned my M4800 for at least 5 years at this point, maybe close to 6 now. It has served me very well but it's really starting to seemingly struggle. Even just doing some web browsing causes it to heat up my lap to an uncomfortable level, something I don't remember it doing years ago (i don't use it as often as I used to so maybe I'm just mis-remembering).

I've already taken it apart and re-applied thermal paste to both the CPU and GPU which at a minimum helped reduce throttling problems I was noticing (and reduced fan noise). Are there any other options to keep it a bit cooler?

 

If you use hwinfo or throttlestop, can you see what core temps you're getting? What power plan are you using?

 

I don't recommend anyone to use too old laptops. I think laptop's good lifespan is about 4 years.
I was lucky enough to buy a new old stock M4800 that was never used until I purchased it three months ago. Buying a new old stock item will be better maybe... I paid only $250 (incl. shipping) for my M4800.

When I use battery-powered electronics from 2014, I don't feel secure... because they're all out of warranty. In case they cause problems, nothing can be done to compensate you. Eventually, I sold all of my old mobile devices for cheap price.

I had a seven year old M4600 and It was riddled with all kinds of problems. I smashed the laptop and thrown it into a trashcan. Never felt safe when using it. I paid $70 for its M5100 graphic card but now the card worth only $25 on ebay.. it's not even worth reselling because you'll be charged ebay fee and paypal fee.

 

No battery will last that long under regular use. But a well cared for laptop with a new battery is definitely usable. My M4800 is still great, on it's third battery now (I've also replaced a couple dead fans). The screen hinges are showing their age, but the machine itself is solid.

KallDrexx, what CPU is in your machine, and what temps are you seeing? Are both fans definitely still working?

 

I had replaced my battery about a year ago and that did wonders for battery life.

My 4800 has a i7-4800MQ. I believe both fans are working (at least air is blowing out of both exhaust areas) but I'll get temps later tonight. I only just learned about throttlestop so maybe I'll play with that (though I saw some saying m4800 can't be undervolted).

 

Same CPU as mine - I mainly was curious if you had the MX extreme CPU, as that one is known to be a bit of a furnace.

I believe undervolting should be possible, but I'm primarily curious what sort of temps you're seeing - if it's maxing out and thermal throttling, I'd suggest considering re-doing the paste job.

 

Well apparently you can just ignore me. I guess I'm just not used to using a laptop in a while.

Temperatures are fine on battery, maxing out at 64C (not even hot enough to spin up the fans to audible levels, though there is some air coming out). It just feels warm right when resting on my leg but when I feel the underside with my hand it's perfectly fine.

 

Glad to hear it! Maybe there were some Windows Updates or Maintenance tasks running in the background that are completed now?
