I own gx740 with i5-430m, 4GB RAM, and I planned to do some upgrades.
Currently I did:
- upgrade SSD, move HDD to dvd drive space
- have some unlocked bios (but didn't found usage for it currently)
- have modified vbios but not sure if the values I've used are good
I was thinking about:
- upgrading CPU to i7-640M
- upgrading RAM (not sure which will fit)
I would like to also:
- fix broken/cracked frame around screen, but it wont be easy and cheap I guess?
- replace screen to something brighter (?) but this will probably not be worth the cost
1) What do you guys think about it? Is it even worth?
2) I've also see something like 'grain effect' moving grey stripes on same page elements (long time I remember it could be related to faulty bios/vbios)?
I picked up a Dell 680m - vBIOS 80.04.5B.00.02 - I think it is a 2GB version after doing some photo comparisons online.
After doing some research I fitted it into my Clevo P150HM hoping it would work, but and I get no POST, the LCD screen is blank, the HDD light does show activity but after ~ 15 seconds or so, 3 blinking lights appear on the left (power light, caps and insert buttons?) and the computer beeps about 4 times before it completely powers off.
I'm guessing that I'm going to need to flash it to a clevo bios since the clevo bios doesn't recognise the dell vBIOS?
I am running the latest 1.01.14 bios and 1.00.13 EC firmware for my P150hm.
Does anyone have any ideas on what I can do? I thought i would at least get a POST but then struggle with the driver installation but i cant even get it to POST...
Hi everyone, I have an unusual request. I have an i7-3940xm in my M17xr4 and it's difficult to keep cool. I have already done the m14x fan mod and I'm using Thermal Grizzly Kryonaut thermal compound... it's just not enough. The CPU is constantly being throttled (my bios settings in a11 unlocked are set to throttle it 85 C) when under load, and it will sometimes see temperatures in the mid to high 90s. The maximum operating temperature is rated at 105C, and I have a thermal shutdown set in bios for 100C, which it hasn't yet reached (but it gets scary close). Even when throttled, it's still an upgrade and runs better then the stock 3630qm, but I don't wan't it to throttle all of the time. I know I could underclock it, but what's the point of having an upgraded CPU if you're just going to downclock it to similar specs as the original (baring cache, of course). At idle, by the way, it jumps around mid 50s to high 60s.
Anyway, to keep it cool, I want to try using a peltier cooler. They're thermoelectric ceramic devices of which one side gets hot and the other gets cold when an electric current goes through them, for those who didn't already know. I figure I can sandwich it between my cpu and the heatsink and try to help keep the cpu's temps a little more reasonable. I have one of a workable size which can withstand temps of up to 135C, and I've done the math with it's specs so that it hopefully knocks 25ish degrees off while at full load and not overheat the peltier doing so. This leads me to my question/request; I need to know if anyone would know a place on the motherboard which supplies voltage when the laptop is running, but not when it's off, whether or not the charger/battery is connected? I have found a few good sources on the MB which can withstand the drain, but they're always hot, even when the laptop is off. I have a multimeter and have been probing, but I don't want to disassemble half the laptop and attempt running it in pieces to verify a good source. If no one knows off hand or has any idea, does anyone know of any schematics or files which exist which contain voltage information of various contacts on the m17x r4 motherboard?
I know this is a strange request and most will not be able to assist, but before taking it all the way apart to probe around I thought I would at least ask. I'll make a write-up on how it's done and how well it works if it's successful, as well as a controller circuit if necessary using a teensy 2.0 or something.
I recently bought the new Toshiba RC100 m.2 2242 NVMe SSD for my Lenovo Y510p which has an m.2 port in it.
After installation the SSD wasn't showing up in my BIOS and also not on my OS Win 10 disk management. So I did a bit of research and installed mod BIOS for my Y510p by following the steps in the link: ( https://www.techinferno.com/index.php?/forums/topic/3546-lenovo-y410p-y510p-unlocked-bios-wlan-whitelist-mod-vbios-mod/ )
There are a lot more options in the BIOS menu now.
Even after doing the mod it's not showing up. The SSD works on my friend's "new 2017 dell gaming laptop" which has m.2 ssd support in it. I don't know what exactly to configure my BIOS to make it work. I've just done some hit-and-trial configs which have eventually failed.
If someone can help solve it Pleasee!!
P.S. : I can share all the available options available in the BIOS if required.
