Hi, I own a Lenovo G450 with the following specs:
Intel Pentium Dual Core T4300 2.1GHz
2 GB RAM
nVidia GeForce G105M with 512 MB Dedicated Video Memory
I'm having heat issues that lead to automatic shutdowns and I've taken rather drastic measures to try and fix it. Here's a timeline of sorts:
1. Place laptop on table, use cooling pad. No luck, GPU temperature rises to 110-120 deg Celsius within five minutes and shuts system down.
2. Use compressed air can to clean out fan. No luck. Same 'record time'.
3. Point a stand air conditioner at exhaust. Works, but since I'm staying at a foreign student's dormitory now, that isn't possible anymore, since we're not allowed to keep them; also, power consumption and bills go up, so no go.
Idle temperatures are around 60 deg C for the GPU, 58 tops for the CPU. Under load (before crash), 120 C for the GPU, 87 C for the CPU.
Said load involves ANY kind of game that makes use of the GPU - Bejeweled Blitz (with 3d acceleration off), Call of Duty 4, Team Fortress 2 and more recently, DJ MAX Trilogy, even at lowest resolution and graphics settings! Also tested with Adobe Photoshop CS3 - max load temps are 87C when working with filters in A4 300 dpi, with CS4, 120 (crash temp), with CS5, 120 (crash temp as well)
If anyone knows a solution to this, it would be greatly appreciated. I'm frustrated with the fact that I can't even play the games I buy-hell, even do work I was supposed to do-without this laptop overheating.
