New CPU problems?

[Sam_Goody]

Well, I bought myself a new cpu for my laptop, and... It Works!

Unfortunately, the power on it seems to be a little flaky. When I try to turn the laptop on, it immediately powers off. The second time I press the power button, it powers on, and works well. In fact, I am writing from this computer now. It works pretty well until I decide to try and play games, whereby I've noticed that it can play some games without turning off better than others. Strangely, It seems that it has nothing to do with the specs of the game.

Now I thought at first it might be a power distribution problem, but it seems too perfect how it always won't turn on once, but then does the second time. I also cannot enter BIOS because it suddenly cuts off whenever I try to shut it down as well...

Also my manufacturer does not allow any tweaking  otherwise i'd see if I can modify the power settings a bit so that I can feed the new cpu a bit more power. Now i'm not quite sure what to do.

Does anyone have any suggestion? Please?

Laptop: Toshiba satellite c855-s5350
Old cpu: Pentium B980
New cpu: Core i5-3340m

Did you replace the thermal compound?

What was your old CPU?

1. Have you updated the BIOS to see if it supports the new processor?

2. Is the thermal paste reused or fresh? If its the latter, is it applied properly?

Wow laptop cpu ? ! Pentium to i5 ? !

I have checked to BIOS updates, and mine is second to the most up to date. The new update notes don't seem to mention anything dramatically different, plus this new cpu was already released at the time of that update.

The termal paste is fresh, arctic silver 5. I already reapplied it once after discovering these problems.

Yes. Mainly because the i5 has intel hd 4000 graphics hehehe.

Before the switch to Haswell, you could upgrade some laptops' cpus as they were on sockets. Nowadays, every single modern laptop cpu is soldered. I believe even the modern APUs are soldered

Well OEMs are quite sneaky about that. You should update ASAP.

Paste is fresh, and lappy is NOT constantly overheating. It sometimes gets very hot, but no hotter than the old Pentium inside it before that.

I'm a little scared about these BIOS updates. What if the lappy crashes when I install them... in fact, i'm not even sure if it will be able to install them as it shuts down a little shakily.... Do you recommend I use the old processor for these updates?

I'd do it as quickly as possible just in case. Just don't touch anything while its updating and keeping the laptop on a flat, stable surface.

Well, operation successful. It still does that stupid thing where I have to turn it on twice. I have no reason to believe that it will do any better playing games.

Well, I don't believe it, but it seems to be a bit more stable now. Might only be a coincidence, however.

Nevermind, it cut off just after I finished typing that.
